AWS Lambda vs Back4App

AWS Lambda is a serverless compute service that runs code in response to events without provisioning or managing servers. It supports multiple runtimes including Node.js, Python, Java, Go, and .NET, with automatic scaling from zero to thousands of concurrent executions.

Back4app is a backend-as-a-service platform built on open-source technologies that provides a managed Parse Server environment. It offers database storage, cloud functions, file hosting, and web deployment for building and scaling applications.
