AWS Serverless is a cloud computing model in which the cloud provider (AWS) manages the infrastructure and automatically provisions, scales, and manages the computing resources required to run an application. In a Serverless architecture, the customer only pays for the actual usage of the application, rather than paying for fixed computing capacity.
AWS Serverless computing is based on the concept of functions as a service (FaaS). A function is a self-contained piece of code that performs a specific task, such as processing data or responding to an event. The AWS Lambda service is a FaaS service that allows developers to write and deploy functions in a variety of programming languages, including Java, Python, Node.js, C#, and more.
