The microservices trend is real. In a study of 1502 software engineers, systems architects, and technical architects, 61% claimed their company had been using microservices for the past year. But what makes microservices so good for application development? Of course, it provides the flexibility of developing individual services at the same time, which decreases the time it takes to launch and deliver an application. However, the path to such a perfect SDLC is fraught with difficulties. For years, Trendyol, a Turkish e-commerce firm, attempted to implement a microservices architectural approach. Data ownership, communication patterns, inappropriate project planning, and monitoring, according to their experienced developers, all contributed to an implementation disaster.

There are numerous examples of microservices implementations that have failed - not because the developers didn't comprehend the concept or functionality, but because the implementation was flawed. Microservices design principles enable developers to make important decisions regarding their architecture, frameworks, and tools for navigating the large technology ecosystem. Let's look at some of the technical and business advantages that microservices provide.

Business competency based on service dispersion

The overall architecture of monolithic architecture is determined by technological boundaries. In the case of microservices architecture, however, this is not the case. Such models are discouraged by microservices. The functionality of your business should be the decisive factor in your overall architecture. In a microservices architecture, teams are built based on individual skills in a specific business function.

For example, a microservices-based application's login page may be created by one group of developers, while the payment page service is created by a separate group of specialist engineers.

Decentralized data management

The concept of decentralized data management is embraced by microservices. There will not be a single database for the entire application, unlike monolithic architecture. Instead, the data related to each business service is owned by each service. By doing so, you can isolate the impact of schema changes. Polyglot Persistence is the name given to this method. It's easier to handle updates when data is decentralized across microservices.

Build it, run it, manage it

The DevOps idea is embraced by microservices. As a result, microservices rely on the team that created the service to run and maintain the code in production. This is in stark contrast to how traditional IT infrastructure used to function. Previously, developers were only concerned with creating a specific feature and committing it to a common repository. Other teams were in charge of deployment and keeping track of updates. This adds a second layer to the process, slowing down the deployment of updates.

The DevOps philosophy eliminates an unnecessary process layer by putting the deployment and operation of the service on the team that is building it. Polyglot

One of the most compelling reasons to employ microservices for application development is their technological flexibility. Each service in a microservice has its ecosystem. Other services communicate with each other using regular channels. It has nothing to do with each service's technology stack. Polyglot allows developers to choose from a variety of technical stacks or database solutions to solve the problem at hand, depending on the situation.

Black box

Every microservice is specified as a self-contained black box. Other services are kept in the dark about the real nature of their intricacy. The only way they can communicate is through well-defined APIs. This reduces the risk of dependent sharing or dependency proliferation between microservices.

Conclusion

In today's world, developing an application needs a lot of planning and consideration. Flexibility, scalability, maintenance, and support are just as important as building a world-class program. Developers can breathe easily when they use microservices since their enhanced capabilities handle the complexities of program development. Please let me know if I missed any key features!
