Multiple processes in a distributed system (no shared memory) need to enter a critical section. No global clock exists. Messages can be delayed or reordered.
The book aims to provide a solid foundation in the principles, architectures, algorithms, and paradigms of distributed systems. It bridges classical theoretical concepts (Lamport clocks, mutual exclusion, election algorithms) with modern trends (cloud computing, peer-to-peer networks, web services). The authors have an academic/practitioner blend, which shows in their structured explanations. Distributed Computing Sunita Mahajan Seema Shah 11.pdf
