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.
In order to perform these operations, we have to write our backend logic. We will create a Lambda Function for that. Then we build a Blog API using AWS API Gateway and integrate that with our lambda function. When a user invokes our Blog API, API Gateway routes the request to our Lambda function. The Lambda function interacts with DynamoDB and returns a response to API Gateway. API Gateway then returns a response to the end user.
Building a Serverless Blog with AWS Lambda and API Gateway
AWS Lambda is a serverless computing service offered by AWS. It enables you to run code in response to events without the need to manage servers. This event-driven service charges you based on actual compute time, making it cost-effective. Lambda supports various programming languages, scales automatically, and seamlessly integrates with other AWS services, making it an ideal choice for building dynamic applications with minimal operational overhead.
