AWS

Choosing the right region affects latency, cost, and legal compliance.

Security in AWS starts with IAM — who gets in and what they're allowed to do.

EC2 is the virtual server where you run your applications in the cloud.

S3 is the backbone for file storage, backups, and static sites in AWS.

A VPC is your isolated private network — the basis of any secure AWS architecture.

AWS manages databases for you so you focus on the app, not maintenance.

Lambda runs your code without managing servers, and you pay only when it runs.

To handle load and stay available, you must distribute traffic and scale automatically.

When you move containers to production, AWS offers managed services to run and scale them.

In production you must see system health via metrics and alarms before customers complain.

Instead of clicking in the console, define your infra in repeatable, reviewable code.

A single cloud security mistake can mean a data breach or a massive bill.

Good cloud design balances performance, reliability, and cost instead of burning budget.
