Modularizace monolitické aplikace

The goal of this diploma thesis is to propose a reference model of a component architecture for a monolithic application delivering the business logic of the internet banking. The first chapter describes the theoretical background based on a literature review relevant to the topic of this thesis, which is software architecture and its three types, such as monolithic application, microservices and modularized monolith. Then the methods used to obtain important inputs for a modularization are introduced, followed by the definition of modularization itself. The second chapter describes the problem of this thesis, which is the monolithic application and its positioning in the application architecture. Then the requirements limiting the modularization process are determined. The third chapter describes the methods that are used in this thesis. Their results are written in the following chapters. These are Component Business Modeling and Domain Driven Design, according to which a component business map and a domain model defining bounded contexts are constructed. Furthermore, design of the component architecture in a business perspective is described, which includes three architecture variants. Each variant prefers one of the defined characteristics of modularization and microservices, such as a high cohesion with a low coupling and a granularity of deployable units. The last chapter is devoted to the technical view of the components. It describes the structure of the modules, the method of the integration and the technical modules proposed in the business view of the component architecture.
