Description

Modern web applications often contains sophisticated features like authentication, geohashing and realtime messaging. In this learning path, you will see how to develop a serverless backend to deploy features. You’ll also learn how to load-test an application, and how to use CI/CD processes to automate deployment.

With a serverless backend, your apps can scale to hundreds of thousands of users without you managing a single server. For serverless builders developing applications for startups or enterprises, this approach allows you to quickly handle complex tasks and focus your development efforts on business logic.

Ask Around Me is a sample application used to showcase these solutions, and both the frontend and backend are provided. The front-end is a Single Page Application (SPA), and the backend is deployed using the AWS Serverless Application Model (SAM). The architecture uses serverless services like Lambda, API Gateway, and DynamoDB. You will see how this sample application uses AWS services to provide a scalable implementation of common, modern web app features. You can use and customize these patterns in your own applications, helping you create scalable web apps and improve your time-to-market.
