The debate of “which is the right kind of software architecture?” has always been in the air. As a consequence, we do harbor doubts when it comes to picking sides or making decisions.  
This blog is going to brush up on the basics surrounding SOA and Microservices Architecture. 
Before we begin discussing the similarities and differences between SOA and Microservices Architecture, let us first understand - 

- What is SOA? 
- What is Microservices Architecture? 
- Advantages of Microservices 
- How are they similar and different at the same time?

SOA or Service Oriented Architecture is a software architectural style that defines a way to reuse software components or services using a service interface that uses a common language network. A service is a self-contained unit of a software functionality or set of functionalities that contains code and data integrations to carry out specific tasks. These tasks could be - signing into a website, processing an application form, or checking a customer’s credit/rewards. 
The reusability of these services or software components is possible because the service interface provides loose coupling between them, i.e., we can call any one of them, as it is not dependent on the pattern of integration implemented underneath. 
This feature is both a risk and a benefit. It is because they have shared access to the ESB (enterprise service bus), and if an issue arises in one service, the other connected services would also get affected.

SOA, which emerged in the late 1990s, proved to be a turning point in the evolutionary stages of software development, as it facilitated connectivity between a monolithic application to a data or functionality of another system. Before its origin, developers had to recreate point-to-point integration in each new project.
