Commits form one of the core concepts in git. They are snapshots of your branch at a certain point, recording your code changes. When you create a new commit, you usually add a message that describes your code changes. The commit messages are the logs of your changes. In multiple…

This post is the second and final of the series where we talk about Encryption. We went over some encryption theory in the first post and introduced how Encryption works in AWS (server-side Encryption). In this post, we will go over client-side Encryption, which is the technique of encrypting data…

Assume you’ve been asked to create a VM on AWS to run some critical operations for your business; it needs to access the internet, but only can be accessed by the maintainers (e.g. people/services who would want to install/upgrade the software). How would you do it? This is a series…
