Flp distributed systems
WebThe impossibility result about consensus in (pure) async distributed systems tells us that we cannot solve problems we want to solve in (pure) async distributed systems without some additional "stuff". This leads to async models where we can solve consensus, e.g. randomized algorithms, fault detectors, partial synchrony models, etc. WebAlso known as distributed computing and distributed databases, a distributed system is a collection of independent components located on different machines that share messages with each other in order to achieve common goals. As such, the distributed system will appear as if it is one interface or computer to the end-user.

A fundamental problem in distributed computing and multi-agent systems is to achieve overall system reliability in the presence of a number of faulty processes. This often requires coordinating processes to reach consensus, or agree on some data value that is needed during computation. Example … See more The consensus problem requires agreement among a number of processes (or agents) for a single data value. Some of the processes (agents) may fail or be unreliable in other ways, so consensus protocols must be See more The Paxos consensus algorithm by Leslie Lamport, and variants of it such as Raft, are used pervasively in widely deployed distributed and cloud computing systems.
