AWS Lambda and API Gateway are two powerful tools that serve very different purposes, but work hand-in-hand to create seamless serverless applications. Let’s break it down with an analogy to make things clearer
AWS Lambda:
Imagine having a chef in a restaurant. The chef only starts cooking when an order is placed, and once the dish is prepared, they stop working until the next order comes in.
Lambda only runs when there’s a specific task to complete like processing data or executing code. And just like you only pay the chef for the food they make, you only pay for Lambda when it’s doing work.
API Gateway:
Now, Think of as the waiter in the same restaurant. The waiter takes orders from the customers, passes them to the chef, and then brings the finished dishes back to the customers.
API Gateway is the middleman, ensuring that customers (users) can interact with the backend services making sure requests are handled and responses are delivered properly.
To be more specific, API Gateway acts as the frontend receiving HTTP requests from clients. It exposes APIs to interact with backends.
AWS Lambda is often the backend where the actual business logic or data processing occurs. AWS Lambda executes code in response to triggers.
And you? What’s your story with AWS lambda and Amazon API Gateway?
