<< ---------------------------------------------------------------- >>

API Gateway: program that sits between a single entry point and multiple backends. Allows for throttling, logging, routing logic or formatting of the request and response

Amazon API Gateway

is a solution for creating secure APIs in your cloud environment at any scale.

Supports three types of APIs

1. Rest API(API Gateway V1)
   1. complete control over req, res
   2. most feature rich
   3. higher costs
   4. both private and public api options
   5. you can import Open API 3 files when creating your API
2. HTTP API(API Gateway V2)
   1. low latency
   2. simpler feature set
   3. low costs
   4. only public APIs
3. WebSockets API
   1. persistent connections for real-time use cases such as chat applications or dashboards

REST vs HTTP API Gateways

API Gateway REST Components

1. API:
   1. Resources (routes)
      1. Methods (GET, POST)
      2. Integration
         1. lambda
         2. http
         3. aws servcies
         4. vpc link
         5. etc

API Gateway HTTP Components

1. API:
   1. Route
      1. Respresnt an endpoint (basically both the resource and the method together(post /hello))
      2. integrations
         1. more limited than REST
         2. VPC link
      3. Stages
         1. versions of API
