I dig into AWS CLI a little bit to explain how we can use JMESPath expressions to apply client-side and server-side filtering and bulk tag instances of an Auto Scaling Group.

I had some fun playing with Route 53's routing policies.

I picked up a task to migrate our base image from Amazon Linux to Amazon Linux 2. Here's what I needed to get it to work.

The VPC Reachability Analyzer tool is a network diagnostic tool from AWS. In this post I look at how effective the VPC Reachability Analyzer tool to diagnose a network connectivity issue from a VPC peering connection to a private subnet.

November end/December is a fairly exciting time for a lot of AWS enthusiasts - it’s time for re:Invent, AWSs' annual event which brings in tens of thousands of AWS users, enthusiasts, power users, customers and more. For the AWS Heroes, it’s also the time to get together, talk, mingle, discuss and debate on all things AWS and more. It’s the time where we pack our bags and head off to Las Vegas.

Folding@Home(aka FAH) is a distributed computing project. To quote from their website, FAH is a distributed computing project for simulating protein dynamics, including the process of protein folding and the movements of proteins implicated in a variety of diseases. Folding@Home involves you donating your spare computing power by running a small client on your computer. The client then contacts the Folding@Home Work Assignment server, gets some workunits and runs them, You can choose to have it run when only when your system is idle, or have it run all the time.

I’ve always dreamed of being at reInvent and this year, not only do I get to be at re:Invent, I also get a chance to lead a Dev Chat. I’m really excited to be there, to present and more importantly, to meet and interact with other AWS Heroes and re:Invent participants. Last year, I was honoured to being named as one of the Community Heroes and almost made it to re:Invent 2018.

Few days back we were preparing for a big migration & deploy and I was tasked upon to prepare a failover just in case the migration goes wrong.
