Designing Serverless Architectures with AWS Lambda and API Gateway

Introduction to Serverless Architectures

You've scaled your application to handle millions of requests per day. Suddenly, your database connection pool is maxed out, and your servers are struggling to keep up. This is where serverless architectures come in - a way to build and deploy applications without managing servers. In this tutorial series, we'll explore how to design and implement serverless architectures using AWS Lambda, API Gateway, and other AWS services.

The Problem with Traditional Architectures

Traditional architectures require provisioning and managing servers, which can be time-consuming and costly. With serverless architectures, you only pay for the compute time consumed by your application, making it a more cost-effective option. But, how do you get started with designing a serverless architecture?

Why Choose AWS Lambda and API Gateway?

AWS Lambda is a serverless compute service that allows you to run code without provisioning or managing servers. API Gateway is a fully managed service that makes it easy to create, publish, and manage APIs. Together, they provide a powerful platform for building serverless architectures.

Step 1: Setting Up AWS Lambda

To get started with AWS Lambda, you need to create a new Lambda function. You can do this by navigating to the AWS Management Console and clicking on the Lambda dashboard.

aws lambda create-function --function-name my-function --runtime nodejs14.
