Serverless Computing
Serverless computing is a relatively new architecture that takes a different spin on the cloud application architecture. Let's start with a traditional on-premise server-based architecture.
Usually, a traditional application architecture starts with a set of computer hardware, a host operating system, virtualization, containers, and an application stack consisting of libraries and frameworks tied together by networking and storage. On top of all this, we write business logic. In essence, to maintain a business capability, we have to maintain the server hardware, operating system patches, updates, library updates, and so forth. We also have to worry about scalability, fault tolerance, and security at the least.
With cloud computing, the application architecture is free of computer hardware as well as having elasticity. We still have to maintain the OS, libraries, patches, and so on. This where serverless computing comes in—in the words of...
