Optimizing Serverless APIs: Best Practices for Amazon API Gateway and AWS Lambda
Learn how to build low-latency, cost-effective serverless architectures by optimizing Amazon API Gateway and AWS Lambda through caching, request validation, right-sizing, and connection reuse.
Building serverless applications with Amazon API Gateway and AWS Lambda allows developers to scale effortlessly. However, without proper tuning across both layers, your application can suffer from high latency, redundant compute costs, and unnecessary cold starts.
Here are key strategies to optimize your API Gateway and AWS Lambda stack for performance and cost efficiency.
Part 1: Optimizing Amazon API Gateway
1. Choose the Right API Type (HTTP APIs vs. REST APIs)
If you do not require advanced features like API keys, client certificates, or request transformations, choose HTTP APIs over traditional REST APIs.
Benefits: HTTP APIs are up to 71% cheaper and offer lower latency compared to REST APIs.
