Microservices are synonymous with simplification because they transform large monolithic applications into modular systems composed of components that perform specific activities, creating a decentralized architecture and simplifying applications’ development, maintenance and scalability.
Companies are aware of these systems’ benefits, demonstrated by the fact that a compound annual growth rate of the microservices market of 18.6% by 2026 is expected and large companies use them in at least 75% of cases
The advantages of microservices are many. Here are the main ones[7;8] :
WebRatio Platform accelerates the creation of microservices, thanks to the use of the low-code method for defining services, made possible with the creation of data-service applications and the natively cloud-ready architecture.
The Data-Service applications allow you to define the Domain Model of microservices through a visual diagram  that describes the structure of the information the application manages. The Domain Model can also be connected to an external data source and can import and publish the desired objects in the model .
Thanks to the Low-Code approach, with a few clicks, it is possible to publish the CRUD operations (create, read, update and delete)  of each element of the domain, configuring the RBAC (role-based access control) rules for protection and personalization of data access. The result of the automatic generation is an application/microservice that exposes the services’ functioning APIs, the documentation of which is available within the system itself , also useful in the unit test of the services.
It is also possible to create services with complex logic that go beyond the simple creation and publication of content. Using the visual modeling of actions, we describe  the services’ input/output interfaces  and the flow of the execution logic through the composition of many elementary operations  . You can then also expose these services via API by configuring the access rules according to the user’s role .
These Low-Code tools allow you to simplify the development cycle of microservices and integration with external and third-party systems, also increasing development efficiency. Together with the possibility of teamwork, they allow for the adoption of Agile or CI/CD methodologies that let you to focus on the continuous innovation of applications, business systems or customer services, enabling the release of high-quality systems.
