Course Description:	-
Course Objectives:	I) To Explore prevalent issues in designing and implementing distributed systems and learn how to deal with the shared state between separate system processes. Evaluate the challenges and solutions that come into play when an application consists of two or more processes that do not share a common address space. Also, elaboration on issues of security, distributed shared memory and more, synchronization and concurrency programming and model checking in depth. Design of multi-tier applications and multithreading. II) Topics include: Replication and consistency, Transactions,agreement and reconciliation, Structuring of distributed systems, Directories and naming, Accounts and authentication, Distributed storage systems, Concurrency programming and model checking in depth, messaging systems, Synchronization and deadlock avoidance issues, Design of multi-tier applications and Future directions and issues
