Micro services Layer

This is multi layer architecture.

You can also build microservices with many technologies and languages, such as ASP.NET Core Web APIs, NancyFx, ASP.NET Core SignalR (available with .NET Core 2), F#, Node.js, Python, Java, C++, GoLang, and more.

The important point is that no particular architecture pattern or style, nor any particular technology, is right for all situations. Figure 6-3 shows some approaches and technologies (although not in any particular order) that could be used in different microservices.
