Serverless architecture lets you focus on code, not infrastructure. Learn how to build a scalable SaaS backend.
What is Serverless?
Serverless computing means you don't manage servers. You write functions that run in response to events, and the cloud provider handles scaling.
Cost Optimization
- Use provisioned concurrency for consistent workloads
- Implement caching with CloudFront
- Right-size memory allocations
- Monitor with CloudWatch
Conclusion
Serverless is powerful for SaaS startups. Start serverless, migrate to containers when needed, and let AWS handle the infrastructure.
