When talking about the era of microservices, there are some key benefits that make them particularly interesting for developers who are constantly challenging themselves in this field. It all comes down to identifying all the different components of the system, which belong to the same context and build a separate service for each of them.
In this context, it makes perfect sense to have a team in which everyone works on a couple of microservices and the responsibility and maintainability for each one are assigned to a particular developer. This, in turn, makes team communication a lot easier. If there is a need for some new information to be shown on the frontend that hasn’t been exposed through the API, it’s fairly easy to go to the developer and ask them to make the change.
Our new modern agile development doesn’t call for thousands of lines of code. So, when the required change is a small one, such as a new field on the screen, there is no need of building and deploying a new version, as it would be the case with a monolith application.
Furthermore, scaling is another important part of the microservice-based solutions. You can now grow the system with the components that are actually the bottleneck. For example, the file uploading feature has significantly expanded in usage lately. This makes it a great candidate for a microservice – able to scale on its own without the need of multiple instances like the monolith application.
The start is somewhat challenging because at the beginning you will probably need to migrate a huge application and separate the logic into smaller chunks. However, once done, this solution will actually save you valuable time. Time which can be used for each and every other project that comes along. And this is true because you have the possibility to reuse your microservice in many different applications.
For example, if you have a User Management microservice which takes care of the creation of users and managing their accounts, you can add another microservice called Roles Management that takes care of users’ roles and permissions. Basically, any serious system needs components like these, that can probably be used in most of your other projects. This means that your next project doesn’t have to be a whole new thing from scratch. Instead, you can pick existing and already developed microservices and just add them in the application, like features, according to the needs of the app.
In conclusion, you can take advantage of all the benefits provided, cherry-pick your microservices, custom-build your backend and then focus with great attention on the presentation and business logic layers. If we look to the future, after decoupling the backend with a philosophy of microservices, the frontend becomes the most essential part of the application (web, mobile, wearable etc.). You can easily have a combination of design and usability with the whole business logic and orchestrate backend communication with different microservices, in a way, you can let the frontend be a point of control. This will provide the flexibility for excellent user experience across many devices and platforms.
