WebThe distributed state-machine algorithm is interesting because it preserves causality. But it too is less important than the problem it solves. The most important contribution of my … In terms of clients and services. Each service comprises one or more servers and exports operations that clients invoke by making requests. Although using a single, centralized server is the simplest way to implement a service, the resulting service can only be as fault tolerant as the processor executing that server. If this level of fault tolerance is unacceptable, then multiple servers that fail independently can be used. Usually, replicas of a single server are executed o…

Zeebe is based on ideas from event sourcing. This means that all changes to the workflow state are captured as events and these events are stored in an event log alongside commands. Both are considered to be records in the log. Quick hint for DDDenthusiasts: These events are Zeebe internal and related to … See more When you have multiple clients accessing one workflow instance at the same time, you need to have some kind of conflict detection and resolution. When you use a RDMS this is often implemented via optimistic locking or … See more I was talking about event sourcing earlier. Actually, there is a related concept that is important: stream processing. The append-only log consisting of events (or records to be precise) is a constant stream of events. Zeebe … See more Now the event log must be replicated to other nodes in the network. Zeebe uses distributed consensus — more specifically the Raft Consensus … See more To provide fault-tolerance and resilience you run multiple Zeebe brokers which form a peer-to-peer cluster.
