This page provides instructions on how to enable TLS/SSL authentication and encryption for network communication with and between Flink processes.
When securing network connections between machines processes through authentication and encryption, Apache Flink differentiates between internal and external connectivity. Internal Connectivity refers to all connections made between Flink processes. These connections run Flink custom protocols. Users never connect directly to internal connectivity endpoints. External / REST Connectivity endpoints refers to all connections made from the outside to Flink processes. This includes the web UI and REST commands to start and control running Flink jobs/applications, including the communication of the Flink CLI with the JobManager / Dispatcher.
For more flexibility, security for internal and external connectivity can be enabled and configured separately.
Internal connectivity includes:
All internal connections are SSL authenticated and encrypted. The connections use mutual authentication, meaning both server and client side of each connection need to present the certificate to each other. The certificate acts effectively as a shared secret.
A common setup is to generate a dedicated certificate (may be self-signed) for a Flink deployment. The certificate for internal communication is not needed by any other party to interact with Flink, and can be simply added to the container images, or attached to the YARN deployment.
Note: Because internal connections are mutually authenticated with shared certificates, Flink can skip hostname verification. This makes container-based setups easier.
All external connectivity is exposed via an HTTP/REST endpoint, used for example by the web UI and the CLI:
The REST endpoints can be configured to require SSL connections. The server will, however, accept connections from any client by default, meaning the REST endpoint does not authenticate the client.
Simple mutual authentication may be enabled by configuration if authentication of connections to the REST endpoint is required, but we recommend to deploy a “side car proxy”: Bind the REST endpoint to the loopback interface (or the pod-local interface in Kubernetes) and start a REST proxy that authenticates and forwards the requests to Flink. Examples for proxies that Flink users have deployed are Envoy Proxy or NGINX with MOD_AUTH.
The rationale behind delegating authentication to a proxy is that such proxies offer a wide variety of authentication options and thus better integration into existing infrastructures.
Connections to the queryable state endpoints is currently not authenticated or encrypted.
SSL can be enabled separately for internal and external connectivity:
Note: For backwards compatibility, the security.ssl.enabled option still exists and enables SSL for both internal and REST endpoints.
For internal connectivity, you can optionally disable security for different connection types separately.
When security.ssl.internal.enabled
is set to true
, you can set the following parameters to false
to disable SSL for that particular connection type:
taskmanager.data.ssl.enabled
: Data communication between TaskManagersblob.service.ssl.enabled
: Transport of BLOBs from JobManager to TaskManagerakka.ssl.enabled
: Akka-based RPC connections between JobManager / TaskManager / ResourceManagerThe SSL configuration requires to configure a keystore and a truststore. The keystore contains the public certificate (public key) and the private key, while the truststore contains the trusted certificates or the trusted authorities. Both stores need to be set up such that the truststore trusts the keystore’s certificate.
Because internal communication is mutually authenticated, keystore and truststore typically contain the same dedicated certificate. The certificate can use wild card hostnames or addresses, because the certificate is expected to be a shared secret and host names are not verified. It is even possible to use the same file (the keystore) also as the truststore.
For REST endpoints, by default the keystore is used by the server endpoint, and the truststore is used by the REST clients (including the CLI client) to accept the server’s certificate. In the case where the REST keystore has a self-signed certificate, the truststore must trust that certificate directly. If the REST endpoint uses a certificate that is signed through a proper certification hierarchy, the roots of that hierarchy should be in the trust store.
If mutual authentication is enabled, the keystore and the truststore are used by both, the server endpoint and the REST clients as with internal connectivity.
IMPORTANT The IETF RFC 7525 recommends to use a specific set of cipher suites for strong security. Because these cipher suites were not available on many setups out of the box, Flink’s default value is set to a slightly weaker but more compatible cipher suite. We recommend that SSL setups update to the stronger cipher suites, if possible, by adding the below entry to the Flink configuration:
If these cipher suites are not supported on your setup, you will see that Flink processes will not be able to connect to each other.

Keys, Certificates, and the Keystores and Truststores can be generated using the keytool utility. You need to have an appropriate Java Keystore and Truststore accessible from each node in the Flink cluster.
For the externally facing REST endpoint, the common name or subject alternative names in the certificate should match the node’s hostname and IP address.
Internal Connectivity
Execute the following keytool commands to create a key pair in a keystore:
The single key/certificate in the keystore is used the same way by the server and client endpoints (mutual authentication). The key pair acts as the shared secret for internal security, and we can directly use it as keystore and truststore.
REST Endpoint
The REST endpoint may receive connections from external processes, including tools that are not part of Flink (for example curl request to the REST API). Setting up a proper certificate that is signed though a CA hierarchy may make sense for the REST endpoint.
However, as mentioned above, the REST endpoint does not authenticate clients and thus typically needs to be secured via a proxy anyways.
REST Endpoint (simple self signed certificate)
This example shows how to create a simple keystore / truststore pair. The truststore does not contain the primary key and can be shared with other applications. In this example, myhost.company.org / ip:<IP_ADDRESS> is the node (or service) for the Flink master.
REST Endpoint (with a self signed CA)
Execute the following keytool commands to create a truststore with a self signed CA.
Now create a keystore for the REST endpoint with a certificate signed by the above CA. Let flink.company.org / ip:<IP_ADDRESS> be the hostname of the Flink master (JobManager).
Now add the following configuration to your flink-conf.yaml
:
Tips to query REST Endpoint with curl utility
You can convert the keystore into the PEM
format using openssl
:
Then you can query REST Endpoint with curl
:
If mutual SSL is enabled:
For YARN and Mesos, you can use the tools of Yarn and Mesos to help:
Configuring security for internal communication is exactly the same as in the example above.
To secure the REST endpoint, you need to issue the REST endpoint’s certificate such that it is valid for all hosts that the Flink master may get deployed to. This can be done with a wild card DNS name, or by adding multiple DNS names.
The easiest way to deploy keystores and truststore is by YARN client’s ship files option (-yt
).
Copy the keystore and truststore files into a local directory (say deploy-keys/
) and start the YARN session as
follows: flink run -m yarn-cluster -yt deploy-keys/ flinkapp.jar
When deployed using YARN, Flink’s web dashboard is accessible through YARN proxy’s Tracking URL. To ensure that the YARN proxy is able to access Flink’s HTTPS URL, you need to configure YARN proxy to accept Flink’s SSL certificates. For that, add the custom CA certificate into Java’s default truststore on the YARN Proxy node.


Hey, have you developed something? Have you ever thought about to deploy it in real time servers? Yes I know there is no place like <IP_ADDRESS>. But if you have some interests about real IT resources then you must learn this amazing technology Cloud Computing.
How did I know about Cloud Computing?
Until I came to know about this technology for me CLOUD is just something that related to rain. the word "cloud" is used as a metaphor for "the internet". so the phrase Cloud Computing is named as such because the information being accessed is found remotely in the cloud or a virtual space.
Few days ago I met with a problem. I need a Linux machine for one of my project . Now I have two options either I have to install Linux in my system along with windows by virtualization or I have to compromise with my windows. But second one is not a good option right. Now trust me if you go with the first option and even you have a good i5 processor with 8gb ram you would suffer from many problems and the whole process takes a big time.
Now If you use cloud for any Linux or windows server you can launch it within 5-10 minutes. Isn't it amazing?
he second reason that you should learn is that suppose you want to host your website or you need a public access to your application. For this you need a web server, you need a database, you need a domain and a public Ip. But if you go to buy this stuffs it costs a huge amount. So how can you host your application? the answer is via cloud. Cloud provides all this services for a very less price.
Why Cloud Computing?Before going to any long definition I want to tell you some basic example of cloud. Suppose Flipkart has 1000 visitors on their website daily .Let they need 100 servers for balance the traffic .But during their big billion days the visitors increased to double but they have only 100 server so they have to manually install another 100 servers before big billion days .But the problem is after big billion days the servers are of no use. But the company has to pay for its maintenance .This is the biggest issue in IT industry before Cloud.
If you use cloud you can increase/decrease your numbers of servers anytime and even you can set a autoscaling group. It automatically increase/decrease the numbers of servers based on you traffic.
What is Cloud Computing?Cloud computing is the on demand delivery of computer power, database, storage, applications and other IT resources through a cloud service platform via the internet with pay as you go pricing model.
Companies that provide Cloud services like AWS,AZURE,GOOGLE CLOUD,ALIBABA enable users to store files and applications on remote servers and then access all the data via internet.
I personally liked AWS(Amazon web services).No doubt all others are very good but AWS has the highest market share (31.7%) nowadays and that's why jeff Bezos is the richest person of the world.
Cloud Service Model:Infrastructure as a Service (IaaS): IaaS is also known as Hardware as a Service (HaaS). It is a computing infrastructure managed over the internet. The main advantage of using IaaS is that it helps users to avoid the cost and complexity of purchasing and managing the physical servers.
Platform as a Service (PaaS): PaaS cloud computing platform is created for the programmer to develop, test, run, and manage the applications.
Software as a Service (SaaS): >SaaS is also known as "on-demand software". It is a software in which the applications are hosted by a cloud service provider. Users can access these applications with the help of internet connection and web browser.
Now from my point of view this technology has a huge demand in IT industry because in the upcoming days, all companies move their infrastructure towards Cloud. Edge Computing is the future of cloud computing. You take any technology nowadays all are using cloud. You can build IOT devices in cloud, every OTT platform are using cloud. I keep this blog very short & simple. If you are learning some technologies like DevOps you can actually do some real time practical using cloud and if you need any help from my side the feel free to contact with my mail id (subhajitchowbey14@gmail.com).

CAST AWAY A film review by Christopher Null Copyright 2000 filmcritic.com filmcritic.com
Only a year ago, Cast Away would have been subject to unavoidable and endless Gilligan's Island comparisons. Now, it will never hear the end of Survivor analogies, and that's too bad, because the film really has no resemblance to either TV show.
Cast Away is The Big Tom Hanks Movie of 2000, the latest in a long line of Big Tom Hanks Movies that stretches back to include The Green Mile, Saving Private Ryan, Apollo 13, Forrest Gump, and Philadelphia. However, Cast Away has the distinction of being the only Tom Hanks Movie to star no one but Tom Hanks.
Just about, anyway. As you've undoubtedly heard, Cast Away largely concerns Hanks' character Chuck Noland, stranded and forgotten on a tiny island in the South Pacific after his plane goes down in the drink. Ruthless in business (living and dying "by the clock,"), yet deep down kind enough to give you the shirt off his back, Noland is a FedEx manager constantly jetting around the globe to fix things that go awry. And that means lots of plane time.
In one of the most spectacular, realistic, and harrowing crash sequences put to film, Noland's sudden Christmas Eve flight goes off course and then plummets into the ocean, only hours after Noland has handed a small, conspicuously ring-sized box to his earthbound girlfriend Kelly (Helen Hunt). Karma and Hollywood being what they are, Noland survives the crash and winds up on the aforementioned island. And get comfy, because he's going to spend a long time there.
Skeptics be damned, Cast Away's finest moments consist of Hanks alone with his surroundings. I never thought it would be any fun to watch Mr. Gump parade around on the beach solo, but it simply is, a testament to the man's serious acting chops. As Noland figures out how to survive against impossible odds -- from opening a coconut to making a fire to collecting fresh water to drink to dealing with a toothache -- I found immense satisfaction in viewing his daily rituals. The actual experience of being on that island would be unfathomable and unbearable. To have turned it into a very watchable movie is unthinkable. And yet they've done it.
I'm not giving anything away that isn't part of the trailer by saying that, years later, Noland escapes his gulag, whereupon he must come to terms with a world that has cast him away (get it?). Unfortunately, once Hanks is back in civilization, the movie completely bogs down with soulful soliloquies, mainly between Noland and his lost girl Kelly, who has had to move on with her life. None of this epilogue offers anything in the way of surprise, mainly because director Robert Zemeckis cuts out what stood to be the most thrilling part of the film -- the first month that Hanks spends back in civilization.  Hell, I start to itch if the TV is off for an hour.
But in Cast Away Hanks is a longhaired near maniac one minute. The next he's shaved and fine, with a little insomnia and sun-bleached hair his only apparent problems, mental or physical. You could have made an entire film about his reconditioning. Or you could have just ended it when he makes his escape. Anything but this hour of padding that leeches from what is otherwise an emotional tour de force.
It is certain that Hanks's name will be up in lights again come Oscar nomination time. The same can't be said for Helen Hunt, an unfortunate casting mistake whose innate, hard-assed unlovability makes you wonder why Noland was interested in her to begin with.
Ultimately, Cast Away rests wholly on the strength of its second act and its leading man. The supporting cast, the editing, the camerawork -- everything else is completely swept aside to make way for our survivor. And that's funny, because if you'd told me yesterday that Tom Hanks, a movie camera, and a whole lot of nothin' would be the recipe for great cinema, I'd have told you to take a flying leap in the ocean.

Online insecurity is an issue that every person who uses the web should know about. Everytime that we post to our social sites, we leave a trail of information that can be used to elaborate a theft. We dont know how much inforamation we actually deposit into the web everyday. There have been many registered cases where thieves use social data to rob, or even worse, to kidnap people. I had been reading about how the advanced technology in new broducts is betraying consumers.  Each of these products are constantly delivering your personaly data to corporate servers and hackers have been known to steal this information from corporate servers.
Knowing that a baby wi-fi camera may be also deliering the feed to someone else is quite discomforting. It is important that we learn about security tips to to keep our date from being reached by others easily. We can minimize who views our information in our social sites. That does not mean that social sites are not collecting data about what kind of products we are likely to buy , but at least pictures and other information is not vicible to anyone. There are several websites that post live feed video of random homes and that is becuase some people dont protect their devices with passwords or set setting to privatize unknown connections. Here is a video on more information about online security.

I am a beginner in C++ and I am getting an error doing my project and its driving me nuts! There may be several errors in this code, I am sure there are, but I can not get VS to compile past this error to tell me whats wrong in the first place.

For this project, I can only use chapters 1-4 of my book, so I don't know what code tags are yet, so can not use those.
I am not sure about your question about how I set it up. I basically had to set up a psuedocode, and then code around it to find the BMI using a formula given to me (BMI = 703*weight / height^2)
I mean when you opened your Visual Studio IDE, how did you create the project that you are compiling? The error seems to suggest the file you've posted isn't included in the project and so isn't being used.

double getWeight = ""; // Used for getting subject weight

double displayBmi = ""; // Used for displaying BMI
line 35 - missing a <<, and I think you want setprecision before displayBmi
line 36 missing ;
Edit: I don't see that you assign a calculated value to displayBmi
Line 36 is supposed to be the calculated value for displayBmi, thats my only other problem I believe is the calculation there, should it be something like
as a seperate line? Also, if my original equation is BMI = 703*weight / height^2 (the ^ being text notation for squared) would the correct cpp be as above?
Ok, fixed the lines above and initialized them to just 0 (i hope that will be right to get the number input? The program is now compiling in Win32 environment with no errors, but still not compiling in blank project, with same error.
and last question (as long as formula is written correctly, what can i put in to hold the window open until key is pressed after final formula is displayed? cin.get(); is not working

In Keller's initial storyline, "Isn't It Bromantic?", Veronica expresses interest in dating Kevin but he is uninterested. As he and Jughead bond over their mutual love of food, Kevin explains that he does not want to date Veronica because he is gay. Kevin also bonds with Veronica and they become best friends.
 "Archie's hometown of Riverdale has always been a safe world for everyone. It just makes sense to have an openly gay character in Archie comic books." Veronica writer Dan Parent concurred, saying "It shows that Riverdale is in the 21st century."
Keller returned in Veronica #205 and headlined his own four-issue miniseries, Kevin Keller, beginning in June 2011. The new series focused on Keller's life before he arrived in Riverdale, including his struggles in junior high school. It also establishes that he is an Army brat and introduces the characters Wendy and William, friends whom Keller had been previously seen texting.
In July 2011, Archie Comics announced that Keller would star in his own ongoing solo title, also titled Kevin Keller. The new series debuted in February 2012 and featured Keller becoming class president while also dealing with "adversity". The series ended in November 2014 after 15 issues.
In April 2015, Archie Comics announced that Kevin Keller would headline another solo series, Life with Kevin. It would be a digital-first mini-series to start with the option to become an ongoing series if successful. The series will bring back creator Dan Parent as writer/artist as well as J. Bone as inker. The series will not take place in Archie Comics' "New Riverdale", instead being set in the classic Archie universe and focusing on an older Kevin who has moved to New York City after graduating from college. The series debuted in June 2016.

About Prolog
Prolog is a programming language that is rooted in
classical logic. It
supports search and unification as built-in
features. Prolog allows us to elegantly solve many tasks
with short and general programs.
Prolog has a pure monotonic
core. The following documents are centered around this important
aspect of Prolog, allowing declarative
debugging and many other approaches that are impossible or
only rudimentarily developed in other programming languages.
A Prolog program consists of predicates. Each Prolog
predicate defines a relation between its arguments. A
relation is a generalization of a function. Prolog
predicates are often more versatile than functions in other
programming languages, and are typically usable in
multiple directions.
Prolog has several
facets that distinguish it from many
other programming languages. In addition, the language has
undergone significant developments in the last few decades.
The increasing availability of more declarative features allows us
to present the language in a more uniform way that is easier to
understand and at the same time yields more general programs with
less effort than was the case with early Prolog versions.
The goal of this material is to bridge the gap between
the great traditional Prolog textbooks of the past and the
language as it currently is, several decades after these
books were written. You will see that many limitations of the
past are no longer relevant, while several new constructs are now
of great importance even though they are not yet covered in any
available Prolog book. If you are new to Prolog, read the
chapters in order for a self-contained exposition of many
important language features. If you already have some experience
with Prolog and would like to learn more about more recent
aspects, I recommend you start with the chapter on
integer arithmetic and proceed with the
chapters it links to.
You can use PceProlog to configure Emacs
for Prolog programming.
About you
You are currently learning or teaching Prolog and find the
existing literature somewhat unsatisfying. Is Prolog still the
same language it was decades ago? Are the existing books
still applicable? If not, what does modern Prolog code
look like?
You can sense that Prolog is a powerful language, yet you are
currently unable to use it to its fullest potential.
In fact, it sometimes seems too limited to you to solve
real problems. On the other hand, you know that Prolog is
the most widely used logic programming language. How can
this be?
Parts of the presented material seem new and unusual
to you, and even contradict what others tell you
about Prolog. In such cases, it is only natural to ask how
legitimate the material is. Can you rely on what the author
is saying?
In 2008, I received a Master's degree from the Vienna University
of Technology after solving a combinatorial optimization
task called the Social Golfer
Problem.
In 2014, I received a doctoral degree from the Vienna University
of Technology in the area of Prolog and constraints. You can
read my thesis. Also since 2014,
my CLP(B) solver
ships with SWI-Prolog. More recently, I have worked
on library(ssl).
My last major contribution to SWI-Prolog
is library(crypto).
Since 2016, I am developing my constraint libraries with Scryer
Prolog and SICStus Prolog as the primary target systems.
See CLP(ℤ), and the
SICStus port of CLP(B) for more
information. As of April 2020, Scryer Prolog ships with these
libraries as built-in features. Other libraries I contributed to
Scryer Prolog
include library(crypto)
and library(format). As of November 2020,
library(format) also ships
with Tau Prolog and
Trealla Prolog.
I am author and co-author of
several scientific publications
about combinatorial optimization, Prolog and constraints. I am
mentioned as one of the contributors to the Prolog teaching
environment GUPU
and have contributed to the Prolog
ISO standard (N226).

VMware Licence Service Service Scope
About this document
This article describes the boundaries of the UKCloud VMware Licence Service (VLS), along with the division of responsibilities between UKCloud and the customer, to facilitate the provisioning and ongoing use of the service.
About the VMware Licence Service
The VMware Licence Service (VLS) is an innovative licensing model designed with VMware to reduce cost and deliver licence flexibility for a customer's existing VMware estate. This flexibility makes it easier to modernise existing VMware environments as the customer's organisation transforms IT services or adopts a multi-cloud approach.
Whether purchasing new licences or providing support and maintenance on an existing VMware estate, VLS enables customers to exchange fixed upfront costs and long-term commitments with a VMware consumption-based licence provided via UKCloud. With this new operations model, the functionality of the VMware licences is identical, only the commercial, cost and commitment term is changed.
Application process
Customers wanting to discuss the suitability of the service and gain a comparative cost estimate for their VMware environment under the VLS programme should contact us at<EMAIL_ADDRESS>or contact your Account Director. To provide an indicative quote, we will need:
The customer's VMware EA number
The total number of active virtual machines and average vRAM allocation
We will then work with the customer to find the ideal solution to suit their requirements.
Once the quote is supplied and the customer wants to place an order, they must provide a purchase order, with a call off contract if transacted within the G-Cloud framework. Once received, the order will be confirmed by our sales operations team.
When we receive an order from the customer, we will create account and login details and send them to the customer.
Service provisioning
To implement the VLS service, there are some simple steps that need to be completed both by UKCloud and the customer. The details that follow assume that the customer has a good understanding of VMware and can carry out the required actions. Note that, if required, UKCloud can provide assistance in these actions at an additional charge, based on our SFIA Rate Card for Professional Services.
UKCloud Portal access
All UKCloud customers have access to the UKCloud Portal, where they can access the My Calls ticketing system to raise service requests. We also use the UKCloud Portal to track and log all customer enquiries, requests, support issues, communications, and information.
Knowledge Centre
To assist customers in using our services and all functionality, the UKCloud Knowledge Centre is continually maintained to provide the latest information. Key articles for VLS are listed at the end of this Service Scope.
Onsite audit
During the initial provisioning of the customer onto VLS, UKCloud will need to conduct a high level audit of the customer's VMware environment, and other connected software, to ensure that there will not be any conflicts, incompatibility or potential support issues.
License keys
To activate the service, UKCloud will make the required licence keys available to the customer. These need to replace the existing licence keys within the customer's VMware environment. The VMware requirements will have been identified in the initial engagement, however, to ensure the right keys are provided, UKCloud Support will engage with the customer to identify the VMware modules that are to be used including the exact version.
UKCloud will request the correct keys, and will make them available to the customer
It is the customers responsibility to replace existing keys with the new UKCloud versions
The customer may be required to update or add licence keys for additional application usage
Licence eligibility
VLS covers the following:
vSphere, vRealize Operations, vSAN, NSX, SRM, plus all other licences captured by the Usage Meter
Existing licence bundles (Essentials Plus Kits, and so on) will be broken into their standard element licence parts
The following are NOT eligible under VLS:
- WSP1, Avi Networks, Velocloud, Carbon Black, Pivotal (until these appear on the product guide)
Usage Meter
The VLS requires the installation of the vCloud Usage Meter on the customer's environment. This Usage Meter captures all of the VMware usage covered by the VLS agreement during the month, and creates a report with the number of units consumed for each VMware bundle. This report with total units is used by UKCloud to calculate the customer's invoice for each month, and enables the customer to be flexible on what they use in any given month, rather than be committed up front.
UKCloud will make the recommended vCloud Usage Meter available to the customer.
UKCloud will provide detailed instructions in the Knowledge Centre for the installation, configuration and reporting of the Usage Meter.
It is the customers responsibility to install and configure the Usage Meter prior to using the service as it is required for reporting and invoicing. The customer can utilise UKCloud Professional Services at an additional cost if assistance is required for this task.
As the Usage Meter is installed in an environment that UKCloud has no access to:
It is the customers responsibility to ensure that the Usage Meter is correctly configured, and that it is collecting the daily data
Customers will need to monitor the Usage Meter to ensure that data is not missing or that the meter has failed. If there is an issue, it is the responsibility of the customer to resolve this issue, or raise a Service request to seek assistance.
It is the customers responsibility to update the Usage Meter when required which will be provided by UKCloud. The customer will be advised as to when the update must be implemented and may be a requirement for the reporting to be accurate.
Usage reporting
The basis of VLS is that the customer is not committed to any specific VMware modules or usage, which converts their VMware usage from an upfront capital expenditure to a flexible monthly operational expenditure. This enables the customer to increase, decrease, test and remove environments and functionality as they require.
As a result, VLS depends on the vCloud Usage Meter to collect the actual monthly usage on an hourly basis. At the end of each month, the report will identify the exact number of units consumed against the set VMware bundle codes.
It is the customer's responsibility to send the output reports to<EMAIL_ADDRESS>within 5 working days of the last day of the reporting month (that is, 7 August 2020 for July 2020 usage). It is essential that this is completed so that the usage can be added to UKCloud's VMware usage and reported to VMware.
If the reports are not received within 5 working days, the customer's assigned Service Delivery Manager will contact them to request the reports
If the reports are not received within 10 working days, the customer's invoice will be estimated based on the previous 2 months' usage. Once the customer's usage is received or estimated, it will be sent to their Service Delivery Manager who will include this in the monthly updates and reports so that the customer can track their usage and costs.
Support
VLS includes your VMware usage and support via our experienced VMware Customer Service infrastructure, which has been responsible for supporting our VMware based public cloud for 9 years. This support is available for all VLS issues or enquiries, and the support availability times are based on the severity of the support ticket.
For more information regarding support hours, SLA and escalation, see the How to raise and escalate support tickets with customer support article on the Knowledge Centre.
Note that there is no limit to the number of tickets that customers can raise.
Customer responsibilities
In addition to the responsibilities already mentioned in this Service Scope, customers are also responsible for:
As UKCloud does not have any direct physical or network connection to the customers environment, it is the customer's responsibility to ensure they are on supported versions of VMware software and that any 3rd party software is within the compatibility matrix. See the following VMware documents for assistance:
The customer is responsible to maintaining their VMware environment including any software and hardware upgrades, including 3rd party software that may affect the VMware environment
Customers may be asked on occasion to run authorised scripts on their VMware environment for the purpose of maintaining the environment, or assisting in fixing reported issues
Customers will be advised as to resolve an issue, and will be responsible for implementing that fix
To assist in the resolution of an issue, the customer may be required to share screens using Microsoft Teams or other collaboration application with our support team.
All support issues must come directly to UKCloud support, and not directly to VMware as UKCloud are contracted to provide support. It is UKCloud's responsibility to escalate an issue to VMware directly if required.
Billing
VLS requires the output of the vCloud Usage Meter, and as this is not available until the end of each month, the customer will be billed one month in arrears.
As an example, the customer must report July 2020 usage to UKCloud<EMAIL_ADDRESS>by the 7 August 2020 (within 5 working days). The customer will then be invoiced for this usage on the 2 September (first working day of September).
The customer will receive a monthly report based on their submitted vCloud Usage Meter usages and total costs.
Cost options
VLS is priced per point consumed and is charged on either a monthly "uncommitted" basis or upfront "committed" basis.
Committed VLS billing. This is the most cost-effective method of purchasing points as it offers additional discounting. The customer will commit to an amount based on estimated usage and this will be invoiced and paid up front. The customer then has 24 months in which to consume this usage which will be drawn down against the initial commitment. Each month, once the customer has reported their usage, their Service Delivery Manager will report on the cost for that month and the points used to ensure that the customer is aware of the amount of points used and what is remaining. At any point, the customer can top up the amount of committed points with either an additional committed order or using flexible monthly billing on a pay as you go basis as detailed below.
Uncommitted VLS billing. To avoid upfront costs, the customer can opt for flexible monthly pay as you go billing. Once UKCloud receives the monthly Usage Meter report, this will be calculated and charged on the next month's invoice (first working day of the month). Although this option does not offer a discounted rate, it enables the customer to be flexible on their usage and may suit customers that are slowing reducing their on-premises VMware estate and migrating to cloud as they have no committed spend. They can therefore cease to use the service at any time, only paying for their usage up to that point.
For full pricing information, see the UKCloud Pricing Guide.
Note that there is a discount level over 100,000 points per month.
Professional Services
This Service Scope sets out the responsibilities of UKCloud and the customer. Although the actions that the customer is responsible for are supported by UKCloud via Knowledge Centre articles and the support team, if a customer requires additional support with their on-premises estate or the installation and configuration of any element of VMware or the Usage Meter, we can arrange for our Professional Services team to assist.
These additional services are charged as per our SFIA Rate Card.
If a customer requires the assistance of our Professional Services, they can either contact our support team or their Service Delivery Manager.

Mr. M.'s Two Thumbnail popups using Twitter Bootstrap Modal
Thumbnail TIP
-
Sometimes thumbnails are not just the same image shrunk down.
Try cropping out an interesting part of the larger image, and shrink that image down for the thumb. The mixer is just a shrunk thumbnail of entire image.
The lion is an example of a "crppped" thumbnail.
View in separate window
- TIP: Name your files mixer.jpg and mixer_t.jpg for easy programming. As you add more thumbs, make sure classes and id's are unique as shown in this example.

After setting the random key values into the key objects the transients scratch which was used as temporary key buffer is cleared by filling it with zeros using the method
Security.arrayFill(Object, short, short, short)
The key generation and clearing of the scratch is a transaction which will be perform complete or canceled (no keys are touched) if any unexpected error occurs.actualState
- expects the actual security state of the applet (from class States)public short eraseKeys(short actualState)
Key.clearKey()
. If all keys are cleared this method will return the new state actualState
- actualState expects the actual security state of the applet. Only clears keys if given actual state is public short getPubKeyAndKeyHandle(byte[] applicationParameter, short applicationParameterOffset, byte[] publicKey, short publicKeyOffset, byte[] keyHandle, short keyHandleOffset)
RandomData.generateData(byte[], short, short)
. Then the FIDO EC private key will be generated by calling the method generatePrivateKey(byte[], short, byte[], short, ECPrivateKey)
with the generate nonce and the parameter applicationParameter as input. The returned FIDO EC private key will be used to generate the FIDO EC public key by calling the method generatePublicKeyPoint(ECPrivateKey, byte[], short)
After generating the public key, the private key will be securely cleared by using method Key.clearKey()
. Then the MAC over the applicationParameter and the nonce will be generated by calling the
method calcMAC(byte[], short, byte[], short, byte[], short)
. The returned key handle is the nonce and the MAC over applicationParameter and nonce.applicationParameter

calcMAC(byte[], short, byte[], short, byte[], short)
.
Then the given MAC is compared with the calculated MAC by using the method Security.secureCompare(Object, short, Object, short, short)
. Only if the MACs are equal the FIDO EC private key is generate by
calling method generatePrivateKey(byte[], short, byte[], short, ECPrivateKey)
with the given applicationParameter and the nonce from the given keyHandle.
The private key will be returned to the calling method in parameter regeneratedPrivateKeykeyHandle

The first input block for AES CMAC will be blinded with a secret inputBlindingBlock
to avoid known plaintext attacks to the AES engine.
To get 32 byte EC private key from AES 128 CMAC (which will only return 16 Byte) we will use two rounds of CMAC with different counter as additional input which is
know as KDF in counter method.applicationParameter
