Learning Objectives
The aim of the course is to provide the fundamentals for the design and implementation of distributed systems. The main metrics for the analysis of a distributed system will be introduced. The systemic-architectural aspects of distributed systems will be introduced, analyzing various models (client-server, multi-tier, peer-to-peer, etc). Furthermore, the course will deal with the main distributed algorithms used in different application contexts. Finally, the main solutions for the realization of modern distributed applications will be described and analyzed.

Learning Achievements (Dublin Descriptors)
Knowledge and understanding: the student will acquire the main knowledge on architectural models, main problems, and peculiar aspects of distributed systems.
Ability to apply knowledge and understanding: the student will be able to apply the knowledge acquired with the aim of designing distributed applications. He will also be able to design and implement prototype distributed systems.
Autonomy of judgment: the student will be able to evaluate the efficiency of a distributed system.
Communication skills: The student will be able to use the terminology of distributed systems appropriately. In addition, the student will be able to illustrate the descriptive characteristics and functionality of a system and distributed applications.
Learning skills: the student will learn the ability to design and implement systems based on descriptive requirements and specifications that specify the type of content and operations necessary for the management of a distributed application.

Project
- Disability and Specific Learning Disorders (SLD)
Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.
To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.

- Assessment
Project, to be agreed with the teacher and oral discussion.
The grade is determined based on the quality of the project and oral discussion.
The quality of the project is evaluated based on the achievement of the objectives of the study, the ability to focus on the central aspects of the course, the ability to identify key performance metrics with respect to the case study, and their evaluation. (For example, in the design of a distributed system, the "beauty" of the graphical user interface will not be evaluated as much as the ability to measure the performance metrics of the system.)
The oral discussion will focus on topics related to the project, but it may range over all topics covered during the course.
- Disability and Specific Learning Disorders (SLD)
Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.
To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
