This is a recent white paper that I have written on building a Connected Retail IT Architecture using a middleware platform. Here we discuss about the typical structure of a Retail IT system and the common problems that we face when building an agile Retail IT. This provides a reference architecture for any Retail IT system and then I try to realize it with the WSO2 Middleware platform. To become a successful business in the ever-changing retail market, the retail business must have a connected retail IT architecture. This retail IT system should be able to connect with existing legacy systems, services, and data. At the same time, it would need to cater to demanding customer needs, flexibility, and agility in exploring new markets, expanding IT capabilities inside and outside the organization (SaaS), and enhance overall performance of the IT system. This white paper will discuss the importance of creating a connected retail system today and explain how a complete middleware platform c...

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...

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...
