Amazon API Gateway: An Architecture Deep-Dive
Amazon API Gateway sits in front of most serverless and microservice architectures on AWS. Three distinct API types, a control plane versus data plane split, a layered throttling hierarchy, a caching layer, a rich integration model. Most teams deploying API Gateway never dig into these mechanics. I have spent years building and operating API Gateway-backed systems handling everything from low-traffic internal tools to production APIs processing tens of thousands of requests per second, and I learned most of the hard lessons the hard way.
