Roadmap phase 3 · AWS core

AWS labs

One visual lesson per AWS topic, in the order the roadmap meets them. Each lesson builds a mental model first (what the thing is, what it costs, how to choose), then points at the Day issues where you build it for real.

How AWS fits together, in four sentences
  1. An account is the bill and the security boundary; IAM decides who may do what inside it.
  2. A VPC is your private network in a region; subnets, route tables and security groups decide what can reach what.
  3. EC2 machines and RDS databases live inside the VPC; S3 stores files outside it, reached through the API.
  4. CloudWatch tells you what is happening, and the bill tells you what it cost. Delete what you are not using.
