Lectures

• Message board is just available from Monday to Friday

Lectures will take place following the (tentative) schedule below.

Overall: The course is structured into three parts: covering fundamental concepts, underlying algorithms, and the development and maintenance of distributed systems.

PART1: BASIC - fundamental and core concepts: This part establishes key terminology, fundamental concepts, and underlying assumptions essential for developing distributed systems.

• Lecture 1 (10.02) - Course overview and fundamentals
  • Industrial Master info slides (Slides)
  • Course overview (Slides)
  • Getting started - 101 Fundamentals (Slides)
• Lecture 2 (17.02) - System models
  • Expected behavior and assumptions (Slides)
• (24.02) - No lecture :(
  • National holiday
• Lecture 3 (03.03) - Communications: RPC and threads
  • Concurrency and scheduling (Slides)
• Lecture 4 (10.03) - Time, clocks and ordering of events
  • Computer synchronization and causality (Slides)

PART2: INTERMEDIATE - Underlying mechanisms and algorithms: This part focuses on understanding the mechanisms and algorithms that are underlying of any distributed system.

• Lecture 5 (17.03) - Logical time algorithms
  • Broadcast algorithms, Lamport and vector clocks (Slides)
• Lecture 6 (24.03) - Coordination
  • Election algorithms (Slides)
• Lecture 7 (31.03) - Replication
  • Quorum (Slides)
• Mid term exam (07.04)
  • The exam covers content from Lectures 1 to 7.
  • It will take place from 10:15 to 12:00 and will start sharply (Please be on time)
  • The exam is written and closed-book, requiring both text-based answers and diagrams.
  • Quizzes are available to reinforce your understanding and help you reflect on the key principles and core concepts covered in the exam.
  • Exam questions require to apply concepts over specific defined problems. Same as exercises done in class during lectures.
• Lecture 8 (14.04) - Consistency
  • Consistency models (Slides)
• Lecture 9 (21.04) - Consensus
  • Paxos, Raft and Chain replication (Slides) Δ
• Lecture 10 (28.04) - Distributed transactions
  • ACID, isolation, serializability, and linearizability (Slides) Δ

PART3: ADVANCED - System Development and Operationalization: This section focuses on designing, deploying, and ensuring the maintainability of your distributed system.

• Lecture 11 (05.05) - Modern system architectures This lecture will be delivered in room 1021
  • From classic (client/server) to explainable and distributed architectures (Slides) Δ
  • This lecture also includes concepts from our research work presented at IEEE International Conference on Distributed Computing Systems (IEEE ICDCS)
• Lecture 12 (12.05) - Scalability
  • Functional decomposition, partitioning and duplication (Slides) Δ
• Lecture 13 (19.05) - Monitoring
  • System execution and behavior(Slides) Δ
• Lecture 15 (02.06) - Planning
