The monolithic architecture pattern is the traditional architectural style that is largely prevalent. A monolith application built as a single, autonomous unit. This structure is based around the concept of a single, indivisible unit, including the server side, client side, and the database. While this style has been an integral part of many businesses, its numerous limitations and issues are motivating more and more to make the switch to Microservices. Monolithic applications are hard to change and it takes a long time. As monolithic applications scale, they can become quite complex, so the overall development is generally longer. Moreover, each change implemented can impact the entire system, requiring an entirely rebuilt and deployed version of software, even if it is a modification just to a small section of code. If developers want to enhance particular features and functions of an application, they have to scale the entire application making the process complex.
Microservices on the other hand allow developers to take a simpler, faster approach towards managing applications by breaking down the monolithic unit into independent ones that function as separate services that communicate with each other through APIs. Every service has its own logic and codebase. However, building an application as a microservice from ground up takes longer, so it would be best to build the application as a monolith and then move towards a microservice approach. That’s because as the monolithic application matures the functions that should be split out into microservices will be more obvious.
The answer is simple – manageability. When applications, or software, are built as a composite of independent, modular components they become easier to manage, maintain and test. They help enterprises be more agile and improve the quality of their workflows and while reducing the time required to improve features or enhance production. As long as the dependencies between microservices are managed appropriately, changes can easily be made to optimize team needs and performance. Microservices have already proven themselves as being a superior system that monolithic applications, especially when it comes to large enterprise applications that are typically developed by distributed and diverse teams.
