Serverless architectures involve building applications and services with infrastructure resources that require zero administration. When building and operating web applications, you have to provision and manage servers to run your application code, install and operate distributed databases, and scale servers to handle API requests. AWS provides you a stack of scalable, fully-managed services that eliminates these operational complexities.
In this session, we will briefly review how you can build web applications using a serverless architecture. We will run through a demo of setting up a simple serverless blogging web application that allows user authentication and the ability to create posts and comments. We will dive into the details of how AWS Lambda, Amazon API Gateway, Amazon S3, Amazon DynamoDB, and Amazon Cognito are used in each component of the web application.
