I’m happy to announce that we just launched WSO2 ESB 4.6.0 .  This release of the WSO2 ESB is a major revamp from the previous versions, where we have improved the mediation performance to a great extent. In addition to mediation performance, the main objective of this release was to conduct an unbiased performance comparison  between popular open source ESBs.  Before moving into the details of the performance enhancements of WSO2 ESB 4.6, let's have a closer look at why ESB performance is so critical. Why ESB Performance Matters?  Today most organizations are moving away from traditional monolithic enterprise applications and adopting SOA as the blueprint for their Enterprise Architecture. When it comes to the realization of SOA, Enterprise Service Bus (ESB) is used as the standard infrastructure. So, ESB is used as the middleware solution that enable the interoperability among the heterogeneous systems and service. In simple terms, if you have used SOA as your Ente...

Paul and myself will be doing a tutorial on ESB and Enterprise Integration at WSO2Con 2013 .  Our main focus will be on Enterprise Integration and how we can use WSO2 ESB  to solve common integration problems. PRE-CONFERENCE TUTORIALS Colombo - Thursday 7th February London - Tuesday 12th February Business success requires seamless information and event flow across departments, customers, partners, and systems. Heterogeneous message formats, protocols, identity tokens, and high message volumes often challenge integration teams. As teams scale Service-Oriented Architecture (SOA) principles of sharing, re-use, and loose coupling across integration participants and interconnect integration endpoints, an enterprise integration blueprint should include a robust and high-performance Enterprise Integration Platform. The Enterprise Service Bus is a core of this platform, enabling interconnection, mediation, management and transformation. Additionally, Registry, Message Broker and Data...

Service Chaining/Service Orchestration  R ecently, I wrote an article on Service Integration with WSO2 ESB. The main objective of that article is to demonstrate how multiple business functionalities can be integrated as an aggregated virtual service. Service Integration is a common integration problem that many organizations need to solve. This article, gives you a comprehensive understanding on how we can integrate a set of services with the use of the WSO2 ESB. An overview of fundamental concepts relating to WSO2 ESB is briefly explained, while a typical service integration scenario in healthcare is implemented from scratch.

We have just released WSO2 ESB 4.5.0, the High Performance Open Source ESB,which is the first ESB version based on enhanced WSO2 Carbon 4 platform.  I would like to give an high level overview of WSO2 ESB 4.5.0's new features and improvements.  XPath 2.0 and XSLT 2.0 support In most of the integration scenarios, we need to leverage the new features of XPath 2.0 and XSLT 2.0. WSO2 ESB 4.5.0,  comes with XPath 2.0 and XSLT 2.0 support. Also, we did a major performance enhancement with the introduction of Saxon as the deafult XSLT/XPath engine.   JSON  Integration is all about handling diverse message types. In that context, JSON plays a major role as numerous APIs are exposed via JSON.  In ESB 4.5.0, we introduce a brand new JSON implementation, which can be used to Streaming JSON (JSONStreamFormatter and JSONStreamBuilder) messages through ESB. In case, if we need to mediate message based on the message content (rather than streaming), th...

Recently I did a short screen cast on how to get started with WSO2 ESB .  It'll be a good starting point for all the newbies of WSO2 ESB.

Two Degrees  is a major mobile service provider in New Zealand and recently they have shared their SOA success stories with WSO2 Middleware platform. After evaluating, proprietary as well as open source ESBs,  Two Degrees has decided to uses WSO2 ESB and WSO2 BPS for mobile service orchestration and integration. Quoting, Two Degrees' Software Development Manager Neeraj Satija - "With WSO2 Carbon, we’ve found a strong middleware platform that is enabling us to deliver the innovation, high volume and high performance required to be a mobile market leader." which reflect the power of having a SOA platform rather than a mediation or orchestration engine. The case study can be download from here .

"Enterprise integration remains harder than it really should be. While integration is inherently complex, I felt that one of the major stumbling blocks is the lack of a common vocabulary and body of knowledge around asynchronous messaging architectures used to build integration solutions. Under the guidance of Martin Fowler and Kyle Brown, I teamed up with Bobby Woolf to create such a language in the form of 65 integration patterns" That's a phrase from the introduction of the book "Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions" by Gregor Hohpe,  Staff Software Engineer, Google Inc. and Bobby Woolf. If you talk to any Enterprise Service Bus(ESB) vendor/developer or a SOA architect, you'll never found a person who haven't read 'Enterprise Integration Patterns' book. Even some ESB vendors use the pattern templates(same images etc.) discussed in the book for their graphical flow designing tools of ESB (eg. F...
