Cloud hosting and architecture
- Region selection, VPC, subnets, NAT, bastion.
- Site and app hosting: S3 + CloudFront, Amplify, Elastic Beanstalk, ECS/Fargate, EC2 — by job, not by habit.
- Databases: RDS (PostgreSQL/MySQL), Aurora, DynamoDB.
- Files and CDN, cache, HTTPS certificates.
- DNS on Route 53, mail records, redirects.
- Environments: dev / staging / prod.
Outcome: a diagram of how it works, a live production environment, and clear stages.
