Lesson 153 - Service Based vs SOA

There’s a lot of confusion about the difference between Service-Based Architecture and Service-Oriented Architecture (SOA). Naming things is hard, and unfortunately the names of these two architecture styles don’t describe the differences between them. In this lesson Mark Richards talks about each of these architecture styles and illustrates the differences between them. As you’ll learn in this lesson, comparing these two architecture styles is like comparing apples to oranges—they are both very much different.

Amazing video, Mark, this is one of the concepts, something I couldn't understand even after reading loads of texts from blogs and articles.

From now I am going to link to this video whenever I need to explain this. Thanks for creating it!

It would be great to have a full video about Service-Oriented Architecture. Thanks!!!

For the SOA drawing, it would be great to add a client app to understand workflows. Unfortunately, it's not really clear what happens in the system when a company employee tries to use a system built OTO SOA.

Suppose you have two services sharing the same database. One is about batch building, which involves the production of your batches, and the other is about the quality assurance of those batches. They are two different modules with their own workflows and activities, but it is obvious that since they are in the same database, a quality assurance table has a foreign key to the batch that is under inspection.

Now, if you decide to separate the database, what happens to the foreign key in my quality assurance module to the batches table? Do I still keep the ID without hard checking? Do I need to change it to a link to the resource? Do I have to change it to a "universal code" of my batch?

It's great!. I have a question, there is a section on the AWS page where it mentions how to move from a service-oriented architecture to a microservices architecture, and they give a comment like: "Microservices architecture is an evolution of the SOA architectural style", I thought. which was an evolution of the service-based architecture. This caused me confusion, well I'm going to read the recommended book anyway. Thanks anyway, seriously. Greetings from Peru!
