There has been a greater change in the way systems are actually build in the today world of rapidly evolving information Technology. Earlier we used to have ibm mainframe computers which was not that powerful and efficient in order to perform complex computations. Thus to improve that, system architecture techniques kept on changing and as a result nowdays, we are bombarded with so much of the software architectural patterns to use, most recent one’s are Monolithic software development architectural pattern and another one is microservices based software development architectural pattern.

Let’s start. With monolithic architectural software development pattern; as the name suggests, monolith; means a large standing block, consisting everything in itself. It conveys the same meaning in the software development world, a large block where complete software application is written nothing is distributed based on any of the features, domains, events and business logics, everything is encapsulated inside a single application .

Applications that follow monolithic architectural pattern tends to have lower programming complexity as everything is inside a single block only, thus tracing also becomes very easy as figuring out where things have gone wrong can found at one place only.

Another architectural pattern that we have is the micro service architectural pattern, as name suggests micro service, there are certain individual and independent micro services that perform certain individual operations and combining them with api gateway to make it a full fledged application. To end user its very difficult to find out that the system is built based on monolith or micro service architectural pattern but microservices architectural design pattern has proven that design micro services based application, scalability, reliability and performance can be achieved exponentially.

Microservices works individually based on the segregation that has been implemented, for example an e-commerce can be. Segregated into different microservices consisting of product microservice, order micorservice, checkout micro service, payment micro service and shipping micro service, each micro service would perform their specific operations, like payment service would contains implementation of payments only it won’t process any request of orders or payments for that their respective service needs to be contacted. Hence designing applications in microservices fashion over monolith fashion tends to give us better application performance, improved scalability issues and optimised reliability and resiliency.
