I started exploring Azure at the start of 2020 when my Google Cloud credits expired and I had to explore alternative platform for demonstrating hands-on usecases in TechPrimers. I got impressed initially with the developer experience in accessing the Azure Portal. And also,

In September 2020, I took the “Microsoft Cloud Skills Challenge” by Microsoft as part of their Ignite conference. This earned me a free exam voucher to take up an Azure certification — It lead to the increasing curiosity to explore about Azure services.

Last year, I mentioned about not attending the re:Invent 2019 Live from Las Vegas. This year, I still sit at the same view at home with everyone going through the same experience across the globe. I don’t think it’s a time to be proud about, however I feel we are lucky enough to sustain our work life remotely with less hassle even during this pandemic.

The mind boggling number of registered attendees (500,000+) shows the sheer amount of interest and popularity ofAc Amazon Web Services! Period!

What is Podman? How is it different from Docker?

The hidden blindspot is free tier limits on EC2. In this page, AWS clearly mentions how the hourly usage works in the free tier —

Why did I decide to go to AWS Community day?

This was the second conference which I attended apart from GIDS which I participated couple of times. I wanted to get a feel of participating in a AWS only conference which is driven by the AWS Community Heros’.

Sponsor booths

I paid a visit to most of the sponsor booths and had good catch up with developers from some of the tools which I use. Below is my view:
