AWS Lambda vs. Azure Web Apps

AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume - there is no charge when your code is not running. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app.

Azure Web Apps, a component of Microsoft's Azure App Service, is a fully managed platform-as-a-service (PaaS) offering that enables developers to build, deploy, and scale web applications and APIs efficiently. Supporting a wide range of programming languages—including .NET, Java, Node.js, PHP, and Python—Azure Web Apps allows for the creation of applications on both Windows and Linux environments.
