Azure Functions vs Serverless: What are the differences?
Developers describe Azure Functions as "Listen and react to events across your stack". 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 virtually any Azure or 3rd party service as well as on-premises systems. On the other hand, Serverless is detailed as "The most widely-adopted toolkit for building serverless applications". Build applications comprised of microservices that run in response to events, auto-scale for you, and only charge you when they run. This lowers the total cost of maintaining your apps, enabling you to build more logic, faster. The Framework uses new event-driven compute services, like AWS Lambda, Google CloudFunctions, and more.
Azure Functions and Serverless can be primarily classified as "Serverless / Task Processing" tools.
"Pay only when invoked" is the top reason why over 7 developers like Azure Functions, while over 10 developers mention "API integration " as the leading cause for choosing Serverless.
Serverless is an open source tool with 30.9K GitHub stars and 3.43K GitHub forks. Here's a link to Serverless's open source repository on GitHub.
Droplr, Plista GmbH, and Hammerhead are some of the popular companies that use Serverless, whereas Azure Functions is used by Property With Potential, OneWire, and Veris. Serverless has a broader approval, being mentioned in 117 company stacks & 44 developers stacks; compared to Azure Functions, which is listed in 30 company stacks and 22 developer stacks.
