Microservice architecture

Away from rigid monoliths to flexible microservice applications

Digitalisation is forcing companies to react flexibly to changing market requirements and shorten their time-to-market. Large, monolithic software systems can often no longer cope with this flexibility. Microservice architecture maps business functions in independent modules to avoid inflexible monolithic design.

Benefits of microservices

The use of microservice architecture simplifies the development, operation and maintenance of a software application.
The benefits of microservices can be divided into five areas:

Agile implementation of technical requirements
Technical decisions can be made individually for each microservice within an application, since each microservice performs its functions as an individual unit. Requirements for a function can be optimally implemented on a small scale.
Rapid implementation of microservices
Developers benefit from the modularity of the microservice architecture. Services can be built by small, self-contained teams who gather expertise and operate the services in the most optimal way. Microservice modules are usually released using a continuous integration system. Due to the strict interface segregation, each microservice can be implemented with its own technology stack. In terms of programming language, there is no restriction to Java, C# or similar.
Simplified quality assurance
Microservice architectures offer simplified quality assurance since each microservice is tested separately. Lengthy, centralised testing over weeks or months is a thing of the past, especially if microservice testing can be automated.
Automated rollout of applications
The rollout of a microservice application is usually automated using a continuous delivery pipeline all the way through to production. Availability of the entire application is thus ensured at all times, even if some of the functionality is temporarily not available.
Efficient operation of microservices
Applications with microservices architecture can react optimally to availability requirements, since microservices usually function in cluster mode or they’re operated in the cloud. Microservice applications are individually scalable, in other words.

doubleSlash is your partner for professional microservice architectures

Why doubleSlash?

By breaking down complex IT systems into smaller, scalable services, we enable you to respond quickly and agilely to the demands of digitalisation.

Our recommendation:

Build small, meaningful units.
Communication between the individual services should be based on HTTPS or a queueing system such as Kafka or ActiveMQ.
Which technology meets the requirements? Select the right technology for your requirements.

Conway’s Law important in the context of microservice development for us, since it forms a good basis for organisational issues:

"Organizations which design systems […] are constrained to produce designs which are copies of the communication structures of these organizations."

Melvin E. Conway

Teams are divided into specialist domains, similar to the departments of a corporate organisation

Development takes place using a realistic approach and in direct coordination with the relevant department
