API Gateway
Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale.
AWS Lambda
AWS Lambda is a serverless computing service provided by Amazon Web Services (AWS). we can create functions and self-contained applications.
With AWS Lambda functions we can perform any kind of computing task, from serving web pages to building backend APIs, and we can integrate lambda with other AWS services as well, here in this article, we are integrating lambda with API Gateway.
Serverless
Serverless is a framework that can be used to build applications on AWS, this will encapsulate things and provide us with a simple structure to create something in AWS. We can Code less and Build more with Serverless.
Build an API Gateway REST API with Lambda Integration
Pre-requisite: AWS
Amazon Web Services is a leading cloud provider which provides us with plenty of Paas, and Iaas, and services that we can use to build and deploy our applications. we going to build and Deploy a REST API with API Gateway which is integrated with AWS Lambda and expose GET and POST methods, here we going to use an open-source framework Serverless for deploying our API.
