Think service not server
In the previous section, you learned about loose coupling and how important it is for our architecture to be loosely coupled for scalability and fault tolerance. Developing service-oriented thinking will help to achieve a loosely coupled architecture (as opposed to a server-oriented design, which can lead to hardware dependency and a tightly coupled architecture). SOA helps us to achieve ease of deployment and maintenance for your solution design.
When it comes to service-oriented thinking, solution architects always tend toward SOA. The two most popular SOAs are based on Simple Object Access Protocol (SOAP) services and Representational State Transfer (RESTful) services. In SOAP-based architecture, you format your message in XML and send it over the internet using the SOAP protocol, which builds on top of the HTTP.
In a RESTful architecture, you can format a message in XML, JSON, or plain text, and send it over a simple HTTP. However, RESTful architecture...
