First off, there are servers in serverless computing. However, the construct of servers is a throwback to a time when the only way to develop distributed applications was to focus on the server as the base component of the infrastructure. In the server-centric model of distributed systems, developers needed to understand their CPU, Memory and OS requirements. An argument could be made that coders only need to concern themselves with code. That’s the point of serverless.

The goal of serverless services such as Lambda, Azure Functions, and Google Compute Cloud Functions is the abstract away the infrastructure. Application developers write code that resides in repositories within these services. An event such as a writing a file to an object store or SQL query initiates the stored function.
