An application about server communication: Using the Command pattern on Web API requests

In modern applications, performing a large number of activities and exchange of information, the architectural approach of microservices is increasingly required. If we make a more detailed analysis of them, they are nothing more than standalone applications that are synchronized in their communication between them, they are interchangeable in certain situations, and they are also divided by functionality. In addition to microservices, the so-called monolithic applications also work with the reception and processing of requests, which architecturally translates into an even greater concentration of functionality in one place and this leads to difficulties in their maintenance. In modern microservice architectures, different methods of communication are often used: microservices often communicate via HTTP with RESTful API design. URLs are used to detect and access microservices. Message Brokers: the use of communications brokers such as RabbitMQ

provides an effective way of asynchronous communication. Whether we are talking about monolithic or microservice applications, it always comes the moment with the growing code, complex service structure and maintenance. In the current development, we focus on the implementation of a new service in a microservice architecture. The goal of the development is to create an application architecture using design patterns and optimization solutions that lead to fast and efficient operations of the business layer, which remains stable in its performance even with a large amount of data to process.
