When you set out to create something, the first thing you’re going to need is a plan, as that will help guide you through the process and ensure that you stay on track. This is true for physical products as well as software and services. When planning a server-side application, you’ll come to a point where you have to decide on the right architecture. The two options are monolithic and microservices, and in this guide, we’re going to cover the pros and cons of each of them in the battle of monolithic vs. microservices.

Choosing the best architecture for a project will make its development smoother and will also make it easier to maintain once it has been completed.

Monolithic vs. Microservices: The Pros and Cons of Each

Monolithic

To kick off the monolithic vs microservices debate, we’ll discuss the advantages of monolithic architecture. A monolithic application is one that is individually packaged and deployed as its own unit, even though it may have an underlying modular design.

The main benefit of monolithic applications is that they’re usually easier to work with since you’ll have fewer variables to worry about. However, since the applications will be larger and more complicated, it will also be harder to make any changes further down the line.

The monolithic architecture also makes an application easier to test out and deploy since it will all be packaged as one. However, testing can often be simpler with a microservices application because it’s easier to see how a change impacts the rest of the program.

Applications that employ a monolithic design will usually have more bugs and glitches than comparable microservices programs. A single glitchy module can end up ruining the whole process.

Microservices

Unlike monolithic architecture, microservices consists of several smaller services with hexagonal architecture working together to accomplish the task. Since the application is made up of building block services, then it is easier to examine on a smaller scale and make minor alterations when compared to a monolithic program.

Since the services are independent, they can also be developed faster, since dedicated teams will be able to focus on each of them. Updating a program with microservices architecture is also made simpler since each of the services exists in a vacuum, ensuring that changes won’t have unintended consequences.

Unfortunately, microservices is a distributed system, which makes it more complicated to work with by its very nature. If you’re leading an inexperienced team, then monolithic architecture will likely be more tedious, but it will still be easier to work with than microservices.

Since the services are separated, it will also be harder to implement application-wide updates, though individual services can be tweaked with greater ease.

Conclusion

In the end, there is no clear winner between monolithic and microservices application architecture, and the right choice will depend on the project you’re working on. We hope that we’ve been able to condense the info and make it a little clearer.
