For courses on Distributed Systems, Distributed Operating Systems, and Advanced Operating Systems focusing on distributed systems found in departments of Computer Science, Computer Engineering and Electrical Engineering. Distributed systems are common. Computer scientists and engineers need to understand how the principles and paradigms underlying distributed systems software and be familiar with several real world examples. No other book systematically examines the underlying principles and how they are applied to a wide variety of distributed systems with the depth and clarity of this presentation. *First part of the book dedicates one chapter to each of seven key principles of all distributed systems -Communication, processes, naming, synchronization, consistency and replication, fault tolerance, and security, provides students with an understanding of the key principles, paradigms, and models on which all distributed systems are based. *Second part of the book devoted to real-world distributed case studies - Includes examples of object-based, document-based, file-based, and coordination-based systems including Corba, DCOM, Globe, NFS v4, Coda, WWW, and Jini. *Numerous end-of-ch

For this third edition of -Distributed Systems, - the material has been thoroughly revised and extended, integrating principles and paradigms into nine chapters: 1. Introduction 2. Architectures 3. Processes 4. Communication 5. Naming 6. Coordination 7. Replication 8. Fault tolerance 9. Security A separation has been made between basic material and more specific subjects. The latter have been organized into boxed sections, which may be skipped on first reading. To assist in understanding the more algorithmic parts, example programs in Python have been included. The examples in the book leave out many details for readability, but the complete code is available through the book's Website, hosted at www.distributed-systems.net. A personalized digital copy of the book is available for free, as well as a printed version through Amazon.com.

Inhaltsverzeichnis Performance I: Caching dynamic web content through aspect-oriented solutions and non-intrusive performance management for computer services. Composition includes true and transparent distributed composition of aspect-components and policy-driven middleware for self-adaptation of web service compositions. Management I: Navigating nondeterminism in replicated middleware applications and trading resources between overlapping overlays. Explore publish/subscribe technology with efficient probabilistic subsumption checking for content-based systems, dynamic load balancing, and decentralized message ordering. Databases: DBFarm offers a scalable cluster for multiple databases, while Queryll enables Java database queries via bytecode rewriting. Mobile and Ubiquitous Computing: Contory serves as middleware for context information on smartphones, enhancing semantic service discovery in pervasive computing environments. Security: A middleware system protects against application-level denial of service attacks, while generalized access control is applied to synchronous communication. Datamining Techniques: FMware provides efficient filtering and matching of XML messages with local data. Synergy facilitates sharing-aware component composition for distributed stream processing systems. Performance II: Enforcing performance isolation across virtual machines in Xen and implementing low-overhead message tracking for di
