Useful or not, here is why you should avoid using Monolith Architecture in your next project.

Following my presentation at the DevFest Ibadan, a lot of folks reached out to me asking why I said having a Monolith will cost technical guys a wave load of bugs.


Following my presentation at the DevFest Ibadan, a lot of folks reached out to me asking why I said having a Monolith will cost technical guys a wave load of bugs. Some went on to raise the point of not wanting to spend on something that isn’t making money yet. Of course, I understand this too well, and I will take my time to explain this in this post. Aside from those who noted the monetization challenge, another group thought that having all stack as a single process enables them to see how the system is doing at a time. Therefore, the focus of this post is simple.

Here, I will elucidate on why breaking a monolith system into an independent component, popularly known as microservices, will help your organization save cost and scaling easily. Let’s get started.

Understanding Monolith

Monolith, running software applications either as a single process or as a small number of processes that spread across a handful of servers.

Microservices is a system architectural design that structures an application as a collection of services that are loosely coupled and
independently deployable. I need not dwell on Monolith because you are used to it, already.

Why micro-services is better

One major advantage of microservices architectures is its swiftness and fast releases in successions. Aside from this, find, below, reasons I am advocating for the use of micro-services on my next project;

Easy to scale: Scalability is the key aspect of micro-services. Because each service is a separate component, you can scale up a single function or service without having to scale the entire application. Monolith can’t help you do this.

Independence can be achieved: Unlike on Monolith, where changes made are effected on a shared library; with micro-services, changes would not automatically be updated across all services. This way, undue development distortions are under check.

Easier understanding: Split up into smaller and simpler components, a microservice application is easier to understand and manage. You just concentrate on a specific service that is related to a business goal you have.

 With Monolith, such unwarranted changes make things like an attempt to fix security bugs slow and equally unreliable to
propagate. On the other hand, business-critical services can be deployed on multiple servers for increased availability and performance without impacting the performance of other services.

Bottom line Advanced technology is fast changing how we build components and fix bugs. Anything process, service, a method that will steal more time than necessary will have to die out naturally. It is for these reasons I have switched to Microservices, and perhaps, you, too, would equally find it worthwhile to make a switch today to microservices architecture for your future projects.
