AKS Supported Kubernetes Versions

Azure Kubernetes Service (AKS) supports specific versions of Kubernetes.It is necessary to regularly monitor the release of new versions and upgrade your AKS clusters to supported versions in order to remain in compliance with AKS Kubernetes Version Support Policy. AKS announces the planned date of a new minor version release and corresponding old version deprecation via AKS Release notes at least 30 days prior to removal. An email notification is sent to the subscription administrators with the planned version removal dates. You get 30 days from version removal to upgrade to a supported minor version release. Patch versions can be released anytime and you get 30 days from the removal date to upgrade to a supported patch version. You should […]

Universal Windows Platform Application on Raspberry Pi

Universal Windows Platform (UWP) provides a common app platform on every device that runs Windows 10. The core APIs in UWP are the same on all Windows devices – including Desktop PC, Mobile Phone, XBox, Hololens, IOT devices and others.  You can target specific device capabilities of a device family with extension SDKs, but you don’t have to do that if you are only using core APIs. Those core APIs include a very impressive set of UI capabilities. What that means is that you can create a UWP application using C# and XAML which will run on an ARM based processor on Raspberry Pi – because Windows 10 IOT Core runs on that. Universal Windows Platform (UWP) has come a long way. I decided to […]

Getting started with Blockchain

Washington DC – May 2019 In this session, we will introduce you to the world of Blockchain technology. We will start with the fundamentals and explain the characteristics and use cases of Blockchains and Decentralized applications. We will explain public Blockchains as well as permissioned Blockchains – with examples from Ethereum and Hyperledger. You will learn how to create a private blockchain to get started. You will learn about Ethereum and how to program Smart Contracts for Ethereum Blockchain. We will also share best practices for secure and effective Smart Contracts development.

TRINUG – Programming Smart Contracts on Ethereum Blockchain

TRINUG – Main Meeting : Programming Smart Contracts on Ethereum Blockchain – August 2018 In this session, Ash will introduce you to the world of Blockchain programming. You will learn about Ethereum and how to program Smart Contracts for Ethereum Blockchain. You will learn how to deploy and test your Contracts on a public Ethereum Testnet. Ash will share best practices for Smart Contract development. You will be able to participate in a hands-on walk-through in the latter half of the session.

Charlotte IOT – Programming Smart Contracts on Ethereum Blockchain

Charlotte IOT – July 2018 You will not want to miss this chance to learn about Blockchain, a technology enabling an entire IoT ecosystem! It has a distributed database for all the transactions, which eliminates the need for the third party to authenticate the transactions. The database ledger is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Charlotte IoT wants to thank Ash Tewari for traveling from Raleigh to share his extensive knowledge and experience around Blockchain. In this session, Ash will introduce you to the world of Blockchain programming. You will learn about Ethereum and how to program Smart Contracts on Ethereum Blockchain. You will learn how to deploy and test your code on a public Ethereum […]

Blockchains for Enterprise

Permissioned blockchains are being developed and used in Enterprise scenarios in which higher transaction throughput, lower latency, versatile confidentiality and governance models are more important than supporting low trust levels among participants. These Enterprise requirements are not being met adequately by the public and permission-less blockchain ledgers. Enterprise scenarios typically have known actors and the trust level between these actors is very high. This allows for trade-offs between trust levels and transaction throughput, speed, confidentiality and privacy, which in turn enables alternate solutions via permissioned blockchains. Hyperledger Fabric (referred to as ‘Fabric’ in the rest of this article) is the leading permissioned blockchain framework, initially developed by IBM. There are other players in this space, including Multichain, ChainCore and the relatively […]
