#Serverless

• Serverless allows developers to build and run applications and services without thinking about the servers actually running the code. 

• It can help create an environment that allows DevOps teams to focus on improving code, processes and upgrade procedures, instead of on provisioning, scaling and maintaining servers.

• Serverless platforms, provided by different CSP:

1. Amazon: Lambda
2. Google: Cloud Functions
3. Microsoft: Azure Functions

• AWS Lambda, let you run code without provisioning or managing servers.

• AWS Lambda executes code only when needed and scales automatically, from a few requests per day to thousands per second.

• Google Cloud Functions is a lightweight compute solution for developers to create single-purpose, stand-alone functions that respond to Cloud events without the need to manage a server or run time environment.

• Azure Functions is an event driven, compute-on-demand experience that extends the existing Azure application platform with capabilities to implement code triggered by events occurring in Azure or third party service as well as on-premises systems.
