Richard Tibbetts discusses Complex Event Processing in the context of High Frequency Trading and the advantages of using high level DSLs, followed by the case study of a system built with StreamBase.
A new strategy for incorporating event driven architecture for scalability and availability of services in the context of SOA. These strategies are based on queuing research pioneered for the use of highly abailable and scalable services, initially in the Web context, but moving into the SOA and Web services context. Actual implementation is described in the context of Mule.
Ian Cartwright presents some of his work (developed with Martin Fowler) on Event Patterns, including: Event Sourcing, Event Collaboration, Parallel Model, and Retroactive Event. These patterns can be used in scenarios where a sequence of domain model changes may need to be recorded, reversed, corrected, or simply observed.
At the peak of the SOA hype, Complex Event Processing (CEP) was hailed as SOAs "next big thing". Since then several CEP solutions have come and gone, and the term CEP is not used as much as it once was. Has it failed to deliver on initial claims or has it simply become a core part of most SOA infrastructures that we take it for granted? And does CEP have anything to offer the Cloud?
This month, Yahoo! released a new open source framework for "processing continuous, unbounded streams of data." The framework, named S4, allows for massively distributed computations over data that is constantly changing. InfoQ examines some of the examples and compares S4 to other technologies.
App Arch Guide 2.0 (Microsoft patterns&practices), Chapter 6, talks about architectural styles like Message-Bus, Layered Architecture, SOA. Beside those styles there are numerous architectural patterns like Plug-in, Peer-to-Peer, Publish-Subscribe. Some authors make a difference between architectural styles, patterns and metaphors.
Dan Pritchett suggests that analyzing streams of events using Event Stream Processor could be an interesting alternative solution to data warehousing applications, which have, in his opinion, important downsides in terms of cost, scalability and reactivity.
Complex Event Processing systems and Event Driven Architectures have been identified as playing a larger role in sophisticated systems today and in the future. What that role is and how it is carried out are up for debate.
At IBM IMPACT this week, IBM announced a several new and re-randed upgraded products dealing with virtualization (Virtual Enterprise), clustering & caching (eXtreme Scale), complex event processing (Business Events), and RESTful web apps (sMash). InfoQ spoke to various execs and product managers to find out more.
