event stream processing (ESP)

Show me everything on SOA event-driven architecture (EDA)

- Event stream processing (ESP) is a software capacity designed to support implementation of event-driven architectures. In an environment where some software entities produce events, other entities manage events, and still others consume events, event stream processing may be properly ascribed to the event manager. This kind of software entity is constantly fielding events, and deciding whether or not to forward them to event consumers for subsequent reactions that can range from simple logging to triggering complex collection of error handling, recovery, clean-up, and other related routines.

In slightly different terms, ESP offers software constructs designed to support event visualization (a dashboard is a classic example), event databases, various forms of event-driven middleware, and even event processing languages. Essentially, ESP provides a set of tools for acquiring and processing multiple event streams to help identify and react to important or critical events in such streams. These tools often include state machines to permit modeling of complex patterns among multiple events, as well as event hierarchies, and event correlation and abstraction tools. You will often find support for event hierarchies, various labels for relationships between events (Such labels include "caused-by, " "member-of, " "timing values, " and so forth), and event-driven processes of all kinds.

ESP is used for various forms of algorithmically based financial trading, fraud detection, process and supply chain monitoring, and so forth.

How EDA and CEP fit in with SOA: Complex event processing (CEP) combined with SOA often gets referred to as event-driven architecture (EDA). Daniel Rubio investigates how much merit this concept has.
SOA and EDA: Using events to bridge decoupled service boundaries: The distinction between service-oriented architecture (SOA) and event-driven architecture (EDA) can be traced to message patterns.
SOA + CEP = 'a new physics of computing': Complex event processing (CEP) represents a paradigm shift in the way applications handle data and can extend SOA into "event-driven architecture."
MiniGuide: End-to-end testing for SOA and enterprise transactions: It is held that the way now to understand behavior of a complex distributed system is by ''following the transaction.'' This is apparent in a series of recent SOA news stories.
