The AWS Lambda service is a fully managed, highly available and highly scalable, processing environment that allows us to process code written in multiple different programming languages without the need to run and configure any infrastructure.

When working with Lambda, the service will orchestrate the creation of the resources required to run our code. Everything from the allocation of resources, building the operating environment, the code interpreter, and the programming language runtimes will be made available by Lambda. All we need to do is bring our code and any dependencies to run it.
