Abstract

Distributed computing have become central concept of how computers are used, from web applications to e-commerce and to content distribution. Distributed computing help programmers aggregate the resources of many networked computers to construct highly available and scalable services. This course teaches the abstractions, design and implementation techniques that enable the building of fast, scalable, fault-tolerant distributed computing systems. A course will cover abstractions and implementation techniques for the construction of distributed computing systems, including client server computing, the web, cloud computing, peer-to-peer systems, and distributed storage systems. Topics will include remote procedure call, preventing and finding errors in distributed programs, maintaining consistency of distributed state, fault tolerance, and high availability. Also topics of multithreading, network programming, and several case studies of distributed computing systems will be considered.
Learning Objectives

Learning Objectives
