Amazon ECS (Elastic Container Service) ECS is AWS’s container orchestration service. Think of it like a manager for your Docker containers - it runs containers, scales them, manages them, keeps them healthy. You have Docker containers. You want to run them on AWS. Without ECS: spin up EC2 instances → install Docker → run containers manually → manage scaling, health checks, load balancing → lo...

CloudFront CloudFront is AWS’s CDN. Think of it like this: you have files in S3 (or EC2, ALB), but users around the world are far away. CloudFront copies your files to servers near users, so they get content faster. Simple example: You have images in S3 in us-east-1. User in Tokyo requests image → without CloudFront, goes all the way to us-east-1 (slow). With CloudFront, gets it from edge loc...

What is S3? S3 is AWS’s object storage service. Basically, you store files here. Accessible via web, unlimited capacity, and crazy durability - 99.999999999% (that’s 11 nines). Buckets: Think of a bucket like a folder, but the name must be globally unique across all AWS accounts. You put files (objects) inside it. Each bucket is created in a specific region. Naming rules: lowercase letters, ...
