You can use the course plan to plan your enrolment (check to see whether the course is being run this semester in the More UOC / The University / Programmes of study section on Campus). Once teaching starts, you'll be able to find it in the classroom. (The course plan may be subject to change.)
This subject focuses on knowing the main concepts related to distributed systems and applications at Internet scale. Distributed applications are systems formed by some, several or many computers interconnected thorough a network and with processes that interact with each other in a complex way, sharing resources and services.

The main objective is to know the organization of distributed systems, their issues and the main algorithms and mechanisms that are used to address them, as well as examples of popular distributed applications.

The general objectives are summarized in:
  • To  know the models of organization of blocks of a distributed system or application and the relationship between them.
  • To understand the difficulties and advantages that can be obtained from exploiting the "apparent" weaknesses of the distribution
  • To know the fundamental aspects and algorithms on aspects such as time, coordination, consensus and replication in distributed systems
  • To know the main aspects of some popular distributed applications

The assessment process is based on the student's personal work and presupposes authenticity of authorship and originality of the exercises completed.

Lack of authenticity of authorship or originality of assessment tests, copying or plagiarism, the fraudulent attempt to obtain a better academic result, collusion to copy or concealing or abetting copying, use of unauthorized material or devices during assessment, inter alia, are offences that may lead to serious academic or other sanctions.

Firstly, you will fail the course (D/0) if you commit any of these offences when completing activities defined as assessable in the course plan, including the final tests. Offences considered to be misconduct include, among others, the use of unauthorized material or devices during the tests, such as social media or internet search engines, or the copying of text from external sources (internet, class notes, books, articles, other students' essays or tests, etc.) without including the corresponding reference.

And secondly, the UOC's academic regulations state that any misconduct during assessment, in addition to leading to the student failing the course, may also lead to disciplinary procedures and sanctions.

This course can only be passed through continuous assessment (CA), the mark for which is combined with a practical (Pr) mark to give the final course mark. It is not planned to have any final test.The formula for accrediting the course is as follows: CA + Pr.
