I am slightly hesitant to write this post, as it might attract some criticism. Nevertheless, I told myself there is nothing wrong with sharing my point of view (even though it might not be well accepted). I would like to share my personal experience regarding yesterday’s Monolithic and today’s Microservice architecture in this post.
Yesterday’s Monolithic Application
20 years back, I was starting my career. At that point, I was working for a large financial corporation in N. America. This financial institution’s middleware platform was running in CORBA, C++ platform. Since CORBA was getting extinct around that time, the technology vendor decided not to support CORBA anymore. It was a huge risk for the enterprise to run its mission-critical middleware platform on unsupported technology. Thus, management decided to port their middleware application to platform-independent technology stack: "SOAP" and "Java," which was considered as the cool kid of the time.
