ROSA is a fully managed OpenShift service with joint support from AWS and Red Hat. It became generally available on 24th March 2021 —

Note: I am a newbie to OpenShift/ROSA, these are the steps that enabled me to get a cluster running on ROSA. If you are an expert on OpenShift, these instructions can look underwhelming ;-)

The objective of this unofficial guide is for newbies to OpenShift like me, to create an ROSA cluster, checkout some of the tools available with ROSA/OpenShift— CLI/Console, deploy a sample Kubernetes service with a simple AWS integration like a AWS LoadBalancer…

This blog (with less talk and more hands-on) will focus on the power of three coming together !!

  1. Graviton2 -AWS Graviton processors are custom built by Amazon Web Services using 64-bit Arm Neoverse cores to deliver the best price performance for your cloud workloads running in Amazon EC2. AWS Graviton2 processors deliver a major leap in performance and capabilities over first-generation AWS Graviton processors.
  2. Amazon EKS — Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service that makes it easy for you to run Kubernetes on AWS without needing to install, operate, and maintain your own Kubernetes control plane…

We just published a blog on Amazon Elastic Kubernetes Service (EKS) being generally available on the Graviton2 processors by Michael Hausenblas , using Graviton2 based instances for running EKS worker nodes

Last year, I published a short blog on running a Corretto based Java application on an Amazon ECS cluster running A1 instances (A1 instances were the first EC2 instances powered by AWS Graviton Processors). I was inspired today by this announcement, to run the same Java application (with the Java run-time from Amazon Corretto) on Amazon EKS and powered by Graviton2 processors. …

This is short summary of some of the key announcements that were announced at the AWS Container Day at KubeCon this week on 17th August 2020 —

Amazon EKS managed node groups now support EC2 launch templates and custom AMIs

Amazon Elastic Kubernetes Service (EKS) now supports using launch templates to customize EC2 instance settings for nodes managed by EKS. When combined, managed node groups with launch templates make it simple to add and update nodes in your cluster, while adhering to any level of specialized security or compliance requirements.

Amazon EKS support for Arm-based instances powered by AWS Graviton is now generally available

Wow, time flies, Java is now 25 years old — it was first launched on May 23rd, 1995 !!

The creation and rise of Java also coincides with my IT/Software career, as I too started working in the Information Tech (IT) industry after graduation in July 1995. I could say, as Java grew with the addition of new APIs and features, I too grew as an software engineer and learnt the different aspects of programming including things like Object oriented programming, Distributed computing concepts, Server side programming, Java frameworks & design patterns and so on ..

This long blog…

This is a very short blog, with lots of screenshots and very less writeup.

Amazon Kendra from AWS, is a highly accurate and easy to use enterprise search service that’s powered by machine learning. Its biggest USP, according to me, is that it supports natural language search and returns the most useful/actionable results. It became generally available to everyone recently —

Well, here comes my requirement - with the COVID-19 epidemic looming large in our lives and most of us are working from home and also helping kids (or trying to help) with their studies ;-) My elder one…

Wordpress running on AWS Fargate with Amazon EFS


Amazon Elastic Container Service (ECS) tasks running on both Amazon Elastic Compute Cloud (EC2) and AWS Fargate can now mount Amazon Elastic File System (EFS) file systems. ECS tasks using EFS will automatically mount the file systems specified by the customer in the task definition and make them available to the containers in the task across all availability zones in the region. This enables persistent, shared storage to be defined and used at the task and container level in ECS.

Applications like Wordpress, Drupal, and JIRA use EFS to store user data and application state, with active/standby container…

This is a small POC that I did to test the AWS Remote Desktop Gateway Quickstart The documentation of the quick start should be enough for hard-core Windows folks, but I am a Windows newbie or rather a lapsed Windows user;-) Hence, this will serve as a ready reference for future and current work. These steps would not have been possible without support from Ashita, from the AWS Premium Support team

When someone asks for a solution to access Windows-based instances using the Remote Desktop Protocol (RDP) on AWS, the most logical service to recommend is Amazon WorkSpaces —…

Note: This is not an official blog or documentation, just a quick summary of the steps that I did to create a custom bundle/image for Amazon Workspaces


Amazon WorkSpaces are virtual, cloud-based Microsoft Windows or Amazon Linux desktops for users. There is exhaustive documentation available at which goes into the nitty-gritty of this amazing service from AWS.

I have to admit that before these past few weeks, though I knew a little about Workspaces, I had really not done a deep-dive hands-on beyond launching WorkSpaces. …
