Service development and microservices

We specialize in leveraging the capabilities of the Google Cloud Platform in application development. Utilizing the microservice architecture in service development saves resources in system maintenance and development.

Service development in the cloud utilizing microservices

We develop new applications for the GCP platform. We take advantage of ready-made cloud components, which accelerates development and enables quick value-added returns directly to the business. In all development work, we take into account the operational aspect, such as SLA needs, right from the start of the project. Often, in order to make further development of an application with cloud components meaningful, it is a good idea to move the application to the cloud before development.

We also take advantage of the microservice architecture in our solutions. Traditionally, functions related to digital services are implemented in a single system, which over time may become quite complex. This complicates the further development of the system and increases the life cycle cost of the solution, for example if the system has to be upgraded to a new platform at some point. A web service implemented using microservices offers a solution to this problem.

ARCHITECTURE

What are microservices?

Microservices separate the different parts of the digital service so that they can be managed, developed and reused freely.
Microservices enable you to expand a system without a whole system rebuild.

With the help of microservices, the ordering, customer data, shopping cart and review functions of, say, an online store or any digital service can be built either partially or completely outside the system. Another typical example is expanding the ERP functions to reduce vendor dependence.

Each new implemented component can be utilized in other systems directly through interfaces and their separate development is much faster, because changes made to a microservice do not affect other parts of the system. In addition, technology choices can be made on a per-microservice basis, so that the benefits of new technologies can be quickly introduced while at the same time eliminating the need for a complete system overhaul.

Why use a microservice-based architecture?

Microservices offer many benefits. From the point of view of server infrastructure, it is essential that each part of the system can be automatically and independently scaled. Therefore, if there are a lot of orders, it will not slow down the whole system, but instead the high load component can be scaled flexibly.

Software development, on the other hand, is facilitated by the fact that each microservice can be developed by its own team. The responsibilities are thus more clearly divided and teams can be assigned microservice-specific KPIs. When a team is responsible for a single entity instead of a vague part of a large system, taking responsibility happens naturally.

From a business perspective, one of the most important benefits is that microservices can be developed to correspond to the real world. The operating logic in each system is modeled so that it directly implements the company’s business logic. In the world of monolithic systems, it is often the case that the platform is forcibly bent in some direction, with changes typically causing a chain reaction of system errors. Each microservice, on the other hand, can have its own business application.
