Failover is the capability to switch over automatically to a redundant or standby computer server, system, or network upon the failure or abnormal termination of the previously active application, server, system, or network. Failover happens without human intervention and generally without warning, unlike switchover. Systems designers usually provide failover capability in servers, systems or networks requiring continuous availability and a high degree of reliability. This book is your ultimate resource for Failover. Here you will find the most up-to-date information, analysis, background and everything you need to know. In easy to read chapters, with extensive references and links to get you to know all there is to know about Failover right away, covering: Failover, Fault-tolerant computer system, Fault-tolerant design, Application checkpointing, Business Continuance Volume, Capillary routing, Chandra-Toueg consensus algorithm, Computer cluster, Consensus (computer science), Data synchronization, Disk array, Disk mirroring, Dual modular redundant, Error-tolerant design, Fail soft, Fail-safe, Fail-silent system, Failure detector, Failure-oblivious computing, Fault-tolerant system, Geoplexing, High-availability cluster, Hot spare, Hot swapping, Lockstep (computing), Log shipping, Log-structured file system, Mirror (computing), Multipath I/O, N-version programming, Paxos (computer science), Processor array, Quantum error correction, RAID, Redundancy (engineering), Redundant array of independent memory, Redundant Array of Inexpensive Nodes, Redundant topologies, Reliability, Availability and Serviceability, Replication (computer science), Round-robin DNS, Self-stabilization, Server farm, Single point of failure, Snapshot (computer storage), Solaris Multiplexed I/O, SpaceWire, Spanning Tree Protocol, State machine replication, Superstabilization, Switchover, Tandem Computers, Toric code, Triple modular redundancy, Uptime, Virtual synchrony This book explains in-depth the real drivers and workings of Failover. It reduces the risk of your technology, time and resources investment decisions by enabling you to compare your understanding of Failover with the objectivity of experienced professionals.
