In this subject you will see a global view of the three architectures of the information systems most used today in the industry. Firstly the monolithic architecture where all the functionalities are in a single module, secondly we will see the family of "clean" or hexagonal architectures which separate the functionalities into different modules and seek to isolate them from the "details" of the application, and thirdly we will explore architectures based on microservices that seek to separate functionality into independent but interconnected applications. We will see the advantages and disadvantages of each of them while referring to the consequences they have in the organization of the teams that develop and manage Information Systems. We will also introduce tools related to DevOps such as containers and the server concept immutable The practices will focus on hexagonal architectures and those based on microservices.
Important: in the practices we use the programming framework Spring boot i SpringCloud which are introduced during the subject Internet Applications Laboratory. It is recommended to have taken it before doing Information Systems Design.
This subject contributes to the following learning outcomes specified for the subject to which it belongs (Services and information systems for organizations)
There will be large group theory classes and small group practice classes. In the theory classes, master class sessions will be combined with problem-solving sessions proposed by the teacher in groups of two or three students.
The practices in the laboratory will be carried out in pairs. They will have to start working in the laboratory with the help of the teacher and will have to finish autonomously outside the regulated contact hours.
1.- Motivation
2.- Introduction to software and systems architecture
3.- Monolithic architectures
3.1.- Characteristics
3.2.- We revisit the architecture in layers
4.- “Clean” or hexagonal modular architectures
4.1.- Characteristics
4.2.- A structure that explains the functionality
4.3.- Ports and adapters
4.4.- Mapping between layers
5.- Distributed architectures: microservices
5.1.- Introduction: “the monolith hell”
5.2.- Modeling: DDD
5.3.- Communication models (synchronous and asynchronous)
5.4.- Transactions and “eventual consistency”
5.5.- Infrastructure patterns
In order to gather evidence of the achievement of the expected learning outcomes, the following evaluative activities will be carried out:
Written test: the student will have to show that he / she has acquired the theoretical knowledge explained in class and that he / she makes informed design decisions. (Evidence of learning outcomes RA1, RA2, RA4, RA5, RA6, RA8). All skills except T2 (teamwork)
Practical test: the student will have to show that he has acquired the practical knowledge. The test will consist of the development of a part of an information system (Evidence of learning outcomes RA2, RA3, RA8, RA9)
Practices: there will be a maximum of 5 practices where the knowledge acquired in class will be applied. (Evidence of learning outcomes RA2, RA3, RA7, RA8, RA9)
Note: all activities are related to all skills. It should be noted that all documentation is written in English so the latest learning outcome and T1 cross-curricular competence are guaranteed. On the other hand to develop the practices the students will have to solve of autonomous form, using the manuals, the problems that go them arise by what the competition B5 also remains guaranteed. The following are the most important aspects of each competence assigned to the subject:
In order to pass (pass) the assessment activities, students will have to demonstrate

Recovery:
The two tests (PR_E and PR_P) can be retrieved separately. The final grade will be calculated as set out above with the test recovery grades.
