These pages are opinionated reference material for people building on AWS. Not certification prep, not marketing overviews. Each page covers a specific service or pattern: what it does, when to use it (and when not to), architecture patterns, CDK examples, and cost considerations.
Written from experience building production multi-tenant SaaS in regulated industries. If something has bitten me in production, it's called out here.
What you'll find
Each page follows a similar structure:
- When to use it: decision criteria, not feature lists
- Key concepts: the mental model you need
- Architecture patterns: how it fits with other services
- CDK examples: infrastructure as code you can adapt
- Cost considerations: what actually shows up on your bill
- Further reading: links to official docs for verification
Who this is for
Architects evaluating services, developers building features, and teams designing systems. If you're looking for .NET-specific code examples (C# SDK usage, AoT patterns, source generators), see the .NET on AWS resources.
If you're coming from Azure and evaluating AWS, the Azure to AWS section covers the migration angle.
