AWS Lambda - Functions as a Service on AWS Infrastructure

AWS Lambda - Functions as a Service on AWS Infrastructure

Getting started with AWS Lambda, Amazons Function as a Service platform

(May 7, 2018) AWS Lambda lets developers write code, execute the code at any scale in the AWS cloud, without worrying about implementing the scaling algorithm. Lambda focuses on very small modules - the name implies Functions, and that is the preferred granularity level. "Function as a Service" platforms are available from several providers, AWS Lambda having been joined by Microsoft Azure Functions, Google Cloud Functions, and IBM Cloud Functions. All are focusing on the same idea, Functions as the granularity level, and automatic deployment and scaling, letting developers focus on their code and the cloud provider focuses on the rest. AWS Lambda is the most developed of these, so lets take a look.

Simple Node.js AWS Lambda function

(May 7, 2018) AWS Lambda has excellent support for Node.js code. As of this writing Lambda supports Node.js 8.10, meaning we have excellent async function support and other modern ES2015+ language features.
