ESB

Best practices in Enterprise Application Integration (EAI) include a Service Oriented Architecture (SOA) and the Enterprise Service Bus (ESB) model to implement a service broker pattern for connectivity, mediation, process orchestration and security.

Security is a key aspect of any successful enterprise SOA solution which allows channels for internal and external parties to access business assets. Security measures should also enable other vital aspects of the solution such as Flexibility - By catering to new security requirements which arise with changing business policies Interoperability - By facilitating secure communication with heterogeneous systems which talk over different security protocols.

In today's world, Enterprise System integration has become an integral part for many businesses. Enterprise application integration can be viewed as developing frameworks and patterns comprising of a collection of technologies and services which form middle-ware to enable inter connectivity of systems and applications across an enterprise. In a nutshell this boils down to linking systems on different business systems such as CRM , SCM , HRM, POS etc to automate and simplify data flow between them to the greatest extent possible.

KeellsSuper is a leading supermarket chain with 50-plus outlets in Sri Lanka, and it offers the only online supermarket in the country.

In 2005, JKH implemented SAP ERP across it’s 70 subsidiaries. With the recent decision to move KeellsSuper from the group ERP deployment to its own line of business (LOB) specific instance of SAP ERP, arose the need for an integrated SAP/POS system.

Some companies have deployed Web services and Web applications for years; others are just beginning to branch out and do so. However, no matter what stage enterprises are at, they need to be properly equipped to manage high volumes of Web application programming interface (API) requests. In their joint presentation at WSO2Con 2011, Paul and Hiranya discussed the real-world challenges of handling high-volume Web traffic, best practices for Web API management, and how to leverage the WSO2 Enterprise Service Bus (ESB). Here are highlights from their talk.

Co-founder and CTO, Paul spearheads WSO2’s overall product strategy. His involvement in Open Source goes back to the original Apache SOAP project, where Paul donated code to enable access to Enterprise JavaBeans. He was a Senior Technical Staff Member at IBM for 9 years and led IBM’s involvement in the Axis C/C++ project. He currently co-chair’s the OASIS Web Services Reliable eXchange Technical Committee, which is charged with creating the industry standard for reliable message exchange over SOAP.

Hiranya first joined WSO2 in October 2007 as an intern where he worked on WSO2’s automated interoperability test framework and implementing finance messaging capability for WSO2 Enterprise Service Bus. Now an Associate Technical Lead, he currently works on WSO2 Enterprise Service Bus and WSO2 Carbon projects. He is an Apache committer for Apache SynapseESB and Apache Xerces2/J. Hiranya is the author of the Financial Information Exchange (FIX) transport for Apache SynapseESB and WSO2 ESB and is a regular contributor to open source projects like Apache Derby and Apache Web Services.

Businesses rely on their enterprise applications to share data, configurations, and other organizational resources. However, connecting these applications—with their diverse programming languages, platforms, data formats and protocols—can be an architect's worst nightmare. In his presentation at WSO2Con 2011, Hiranya discussed how an enterprise service bus (ESB) can be used as a backbone for service-oriented architecture (SOA) integration and provide a simple and uniform platform for connecting heterogeneous applications. Here are highlights from his talk.

Enterprise Integration is a means of linking the different components of an SOA system. The success of an SOA solution heavily depends on proper enterprise integration. However this is easier said than done. There are many complex requirements to this process one of which is the need to interconnect heterogeneous systems which use different message formats and protocols and these systems needs to work together to achieve the final outcome.

In the modern enterprise, complex business requirements are increasingly satisfied by a combination of new and existing services. Getting the right bits of information at the right place, at the right time, in the right format, and with the right protocol can be a challenge. The WSO2 Enterprise Service Bus (ESB) provides a simple solution to this integration problem by providing a rich set of integration capabilities for robust, scalable and seamless integration of such services.
