In today’s world, your digital services and applications must adapt quickly to the ever-changing needs of your users. This is difficult to achieve with conventional monolithic system architecture that always has to be completely revised and made available again. By contrast, microservice architecture can break up large software projects into flexibly interconnected modules, offering more agility. However, microservices also increase complexity and are not always easy to manage. In this article, you will discover how you can manage with these challenges and take full advantage of the benefits of microservices. First of all, we will briefly explain how exactly microservices work.

How Do Microservices Work?

Microservices are small, decoupled applications that provide individual functions and services for application software. Each microservice has a specific task as well as its own self-contained processes. Microservices are developed and provided independently of each other. They don’t even have to use the same programming language, as they can communicate with each other via interfaces (APIs).

The benefit here is that individual microservices can be easily replaced or reintegrated without endangering the stability of the entire application. As a result, you can scale certain services more quickly as your users’ requirements grow. For developers, microservices represent greater flexibility as they can work independently. Errors are also easier to isolate and do not immediately affect the entire application.

What Challenges Do Microservices Pose?

If an application consists of several independent microservices, the complexity of the system increases accordingly. This leads to decentralization.

In theory, this independence means that development teams for individual microservices no longer have to adhere to the specifications and strict technical requirements of a centralized architecture . Instead, they can act completely independently. However, the danger is that the team loses sight of the application’s overall goal.

The fact that microservices can use different technologies and programming languages presents another disadvantage. The system becomes more fragmented and loses the ability to be monitored as an entire unit, which in turn poses challenges to IT governance.

In order to effectively exploit the advantages of microservice architecture, decentralization of the system should be followed by recentralization. You can achieve this by running all microservices on a shared platform. EASY ApiOmat is an example of such a Multi-Experience Development Solution. This approach offers the following four advantages:

1. Microservices work better and faster together

Microservices communicate with each other so that they can function together as part of a larger application. For this purpose, each microservice provides a REST API, which in turn is used by the development teams of all other microservices in order to access it. However, manually integrating this REST API is a very time-consuming process, especially if the application consists of many microservices.

Nevertheless, by adding an additional endpoint with microservice metadata to the REST APIs, the central Multi-Experience Development Platform can generate Software Development Kits (SDKs). Any development team can then use the SDKs to automatically create APIs between microservices. This way, no additional code needs to be written to integrate the REST APIs with each other.

2. Mobile microservices are easy to create

The range of frontends is constantly increasing, and customers expect their applications to be available on all devices. For this reason, existing microservices must also be available on mobile devices such as wearables, voice assistants and apps.

This is where the Multi-Experience Development Platform helps by providing SDKs in numerous programming languages for all kinds of frontend devices. Mobile microservices access the right data via the metadata endpoints, which makes them operational. Regardless of which other frontends are added in the future, your application will always adapt flexibly as required.

3. IT governance is guaranteed

As we have already mentioned, ensuring IT governance is a real challenge in a decentralized microservice architecture. A platform like EASY ApiOmat provides targeted solutions in this respect. For example, you can assign individual users fine-grained access rights for various services, modules, microservices and analytics.

In addition, there is a standardized procedure for auditing, which includes a platform-wide audit log. This way, it’s possible to trace any changes made to meta information, which means that generated APIs and SDKs only have to be audited once. Afterwards they can be used freely.

The Multi-Experience Development Platform also standardizes all APIs and ensures that all data protection regulations are followed. Analytics tools are also already integrated so that you don’t have to transfer data to external tools and other servers for analysis.

4. You can use analytics to measure and optimize your application

The aforementioned central analytics function of the platform collects important data, e.g. about users, devices and sessions, and displays it in real time in a dashboard. This completely eliminates the need to implement individual analytics tools for each microservice. In addition, all data is collected and processed in full compliance with data protection laws.

The analytics function provides valuable insights into the user behavior of your microservices and enables you to make data-driven decisions. It can also be used to analyze errors and program crashes in order to eliminate vulnerabilities in the system. This way, you can constantly work on optimizing your application and adapt it to customer requirements.

Conclusion

Microservices are ideal for driving your digitalization process in a flexible and dynamic manner. With an interconnected Multi-Experience Development Platform, you can do this even more efficiently and quickly while simultaneously mitigating risk.

You can also bid farewell to the repeated creation of already existing components. Instead, easily exchange the microservices in the event of fluctuating requirements and changes in processes or business models. As a result, the time-to-market of your services will significantly accelerate and the customer experience will improve – a win-win situation on many levels.
