Understanding the different Azure serverless services

Before we start to build a backend with a serverless architecture, we need to define what serverless actually means. In a serverless architecture, of course, the code will run on a server, but we don't need to worry about that; the only thing we need to focus on is building our software. We let someone else handle everything to do with servers. We don't need to think about how much memory or CPU (Central Processing Unit) the server needs, or even how many servers we need. When we use services in Azure, Microsoft takes care of this for us.
