COMP689 deals with the major recent developments in distributed systems technology. It explains the principles of distributed systems such as communication, naming, synchronization, replication, fault tolerance, and security using examples and case studies. It covers architectures in distributed systems, reflecting the progress that has been made on organizing distributed systems, and new topics such as peer-to-peer computing, sensor networks, web services, grid computing, virtualization, cloud computing and its roots in distributed systems mechanisms, and self-management of distributed systems.
The course illustrates design concepts for each topic with concept-oriented assignments and a small high-level programming assignment. Students complete a term project on the design and implementation of a real distributed system.
The learning objectives of this course are to
- present the principles underlying the function of distributed systems and their extension to grid and cloud computing and virtualization techniques
- create an awareness of the fundamental technical challenges in advanced distributed systems design and implementation;
- expose students to current technology used to build architectures to enhance distributed computing infrastructures with various computing principles and paradigms, including grid and cloud computing;
- enhance students’ understanding of key issues related to multi-level interoperability across a distributed infrastructure and across multiple heterogeneous and distributed resources in a dynamically changing computing environment;
- expose students to past and current research issues in the field of distributed systems and new challenges in cloud computing; and
- provide experience in analyzing a distributed computing model and implementing typical algorithms used in distributed systems and distributed applications in cloud infrastructure.
A student who successfully completes this course should be able to
- define distributed systems;
- explain why you would design a distributed system and what the desired properties of such systems are;
- list the principles underlying the functioning of distributed systems, describe the problems and challenges associated with these principles, and evaluate the effectiveness and shortcomings of their solutions;
- discuss how the principles are applied in contemporary distributed systems and specific distributed infrastructure such as cloud infrastructure and cloud platforms;
- explain how these principles and features affect software design on specific application problems;
- analyze workflow applications and workflow management mechanisms on multiple virtual instances and the challenges with respect to secure data storage, communications, configurability, performance, etc., in distributed systems and clouds;
- design a distributed system that fulfills requirements for desired properties, be able to recognize when this is not possible, and explain why;
- build distributed system software using various methods, strategies, and techniques presented in the course;
- effectively communicate course work in writing and oral presentation.
- Features and types of distributed systems.
