Amazon API Gateway

Amazon API Gateway works hand-in-hand with AWS Lambda. It makes it easy to create and manage APIs, acting as a bridge between applications and backend services. It ensures security through authentication and authorization and keeps an eye on how the API is used. Plus, it protects against misuse with features like rate limits. This service is crucial for building safe and scalable APIs that connect different parts of a system smoothly. When combined with AWS Lambda, it’s a powerful duo for creating dynamic, event-driven applications....

If you do know which limits make most sense for you, the traditional “in-advance” provisioning will be cheaper. Click on the “Create Table” button at the end. Now, you can see your created table in the Tables tab....
