Why are Microservices the key to your Digital Transformation journey?

One of the primary keys to success in today's business environment is the tight-knit relationship between business and Information Technology. It implies that the day-to-day processes of the organization need to be in tune with IT by bridging the gap between them and focusing on the same goals. Companies need to use microservices to create this seamless digital transition presented here.  

With an increasing need to build better and higher-quality mobile apps, all the while lowering costs and increasing their efficiency, businesses need to reevaluate their approach towards their digital transformation. Instead of relying on large, monolithic systems, they need to migrate to smaller, modular microservices architectures that allow them to build independent components and use them to create complete systems. Together with DevOps, businesses can also bring a dose of consistency in their web development process, continuously building and deploying applications whenever necessary.    

With that said, how do microservices compare to monoliths and what are the advantages of these microservices that makes them such an incremental part of the digital transformation journey?

Microservices vs. Monoliths

Monolith apps do have their benefits. They will allow you to set your deployment once and only adjust the system based on various changes that may appear down the line. Microservices, on the other hand, will require a fair degree of additional work. You will need to deploy each microservice independently and unify the format to reduce the total time required by for each additional microservice. 

The problem with monoliths, however, is that if something goes wrong, the entire project is at risk, whereas with microservices, it's only one piece that's broken. That said, when employing a microservices architecture, a DevOps approach is necessary. It will allow teams to prepare themselves, delegate responsibilities, as well as monitor and maintain the functioning state of the entire CI configuration of each microservice as well as the whole infrastructure. 
Even though it requires more work, by using a microservice infrastructure as part of a company's digital transformation has clear benefits. 

Easier Scalability and Adaptability

When it comes to using resources intelligently, monoliths are quite inefficient. Even if you were to hire more employees, they would still have to work on the whole project. And to make matters worse, it's possible to code in such a way that horizontal scaling would be impossible. Microservices allow for a more targeted approach, with resources allocated to only those parts of the project that require them. 

Similarly, microservices are interchangeable and can be reused. It means that, instead of breaking the entire monolith apart, you will only have to replace that microservice with one that's better suited for the changing business landscape. A company will be in a far better position to foster new business models and be more adaptive to changing needs coming from both customers and employees. 

Improved Reliability

It works on the principle of not keeping all the eggs in the same basket. If one microservice goes down, it will not affect the entire app. For instance, if you are developing a banking app and the microservice responsible for money withdrawal breaks down, only those using that service will be affected since the rest of the app will continue to function. It is not the case with monoliths. 

Faster Releases

Small microservices with a proper communication architecture can quickly release new features by reducing the build time, QAs, and test execution time. Monolith apps, on the other hand, have many internal dependencies that cannot be broken up. There is also the risk of certain features which are dependent on unfinished changes, potentially postponing new releases in the process.
