Lambda

One of the main serverless stack services provided by AWS. It allows you to run application code without the need to create and maintain a server infrastructure (FaaS - Function as a Service). Ideally suited for creating serverless microservice-based applications. The code can be called in many ways and as a result of a multitude of events, such as an HTTP request, placing a file in S3 or receiving an event from CloudWatch. Lambda allows you to run code written in various programming languages, including Node.js and Python. It is a very efficient and highly scalable service that is ideal for creating distributed applications with variable dynamic load levels.
