The learning AWS journey continues. This week was all about storage. Because there were too many things to share, my timeline was quite busy with multiple tweets per day.

At the beginning I started with EBS (Elastic Block Store) and EFS (Elastic File System) which are about HDD type of storage for EC2. That was interesting because I learned about a few hardware terms that I was not aware of.

The week continued with RDS which I initially thought of skipping as “it was the AWS service i’m the most familiar with” but thankfully ended up doing it and learned a lot about how to scale Databases in AWS. Especially the part about Aurora DB was really exciting.

The week ended with ElastiCache which also revealed some great techniques for managing cache. Let’s go straight to the Tweets.


What is an AWS EBS (Elastic Block Store)

A volume in which you store your EC2 data so that they don’t get lost when the instance is terminated

An EBS is network drive which works like a USB stick on the cloud.

⏳ It has a bit of latency

🔌 It can quickly be attached to other instances

🔒 It is locked to an AZ. To move it across you need to snapshot it

💰 You are billed for the provisioned capacity, not the one you use
