Distributed systems engineering and LabModule LAB
Academic Year 2023/2024 - Teacher: ANDREA FRANCESCO FORNAIAExpected Learning Outcomes
General goals described according to the expected learning results.
- Knowledge and understanding: the student will be able to use advanced development mechanisms, i.e. on collabrative and distributed development, validation of complex systems, automation of the release process, design and implementation of distributed systems with microservices.
- Applying knowledge and understanding: the student will be able to design, and implement advanced development, validation and release tools for distributed applications.
- Making judgements: the student will be able to analyse advanced development, validation and release solutions for distributed applications.
- Communication skills: the student will be able to describe advanced development, validation and release solutions using a proper technical language.
- Learning skills: the student will be able to solve typical problems, by studying, analysing and using novel development, validation and release technologies.
Course Structure
Frontal lessons for concepts, techniques and code; practical tutorials with examples of code for the covered topics.
Should remote teaching be needed, then some adjustements to the above might be introduced, while honouring the programme outlined in the syllabus.
Required Prerequisites
Ability to design and implement object-oriented systems.
