Event Processing

Event Driven Architecture (EDA)

• Event-driven architecture (EDA, also known as Message-driven architecture) is a software architecture pattern promoting the production, detection, consumption of, and reaction to events. An event can be defined as "a significant change in state". (Wikipedia)

Characteristics of Event Driven Architecture

• Broadcast communication (+ point to point)

• Timeliness

• Asynchronous

• Fine grained events

• Ontology

• Complex event processing

WSO2 Advantage ?

Use Case : IoT & Cognitive Computing

Summary• In order to adapt to business pressures IT systems should be agile, adaptive

and responsive.• Event Driven Architecture is a architecture style which can support above

needs composed of events, event channels and event processing paradigms.• Event channel is composed of messaging infrastructure and messaging

protocols. Message queues and pub sub are popular concepts and we see hybrid models of those.

• Event processing provide the business value and performed through EPA which may be on a distributed setup.

• WSO2 provide value at every corner on EDA space through its product portfolio.

• IoT and Cognitive Computing is good use case for EDA.
