SOA versus microservices

You'll get confused between microservices and SOA if you don't have a complete understanding of both. On the surface of it, microservices' features and advantages sound almost like a slender version of SOA, with many experts suggesting that there is, in fact, no need for an additional term, such as microservices, and that SOA can fulfill all the attributes laid out by microservices. However, this is not the case. There is enough difference to isolate them miles apart technologically.

The underlying communication system of SOA inherently suffers from the following problems:

• The communication system of SOA inherently suffers from the fact that a system developed in SOA depends upon its components, which are interacting with each other. So no matter how hard you try, it is eventually going to face a bottleneck in the message queue.
• Another focal point of SOA is imperative monogramming. With this, we lose the path to make a unit of code reusable with respect to OOP.

We all know how organizations spend more and more on infrastructure. The bigger the enterprise is, the more the complex is the question of ownership of the application being developed. With an increasing number of stakeholders, it becomes impossible to accommodate all of their ever-changing business needs. This is where microservices clearly stands apart. Although cloud development is not in the current scope of our discussion, it won't harm us to say that the scalability, modularity, and adaptability of the microservice architecture can be easily extended further with the use of cloud platforms. Time for a change.
