This Wednesday the 12th, IBM's Leif Davidsen and I will be delivering the results of and commentary around ebizQ's latest survey results on SOA and trends toward ESB federation. (To sign up for the Webinar, click here.)
To help build the conversation that will be taking place within the Webinar, we invite you to join in with any questions or observations you may have.
One inquiry focused on the viability of Web Services Description Language, or WSDL,in a federated environment. Would exposing ESBs as a WSDL be sufficient to link different vendors' ESBs together?
Leif responds that while WSDL can help make the connection, but more is required for a robust SOA infrastructure across business units. "To make the most out of an SOA infrastructure, resources should be used and reused across the business. This will drive the connection of these ESBs to provide end-to-end seamless connectivity," he said.
"From a purely functional point-of-view a service provider and consumer can connect using a WSDL interface. But when looking at the business perspective, important issues such as Governance, Security, Transactionality and Systems Management come into view. In order to invoke the services through a WSDL interface, the service needs to be located. If it exists in a remote system, the security credentials need to be passed along. Updates to transactions add to the complexity and criticality. And of course not every asset is exposed as a Web Service."
"So while WSDL maybe a part of the solution for connecting web services through different ESBs, there are many other aspects to consider other than simple web services connectivity that will be important to businesses when considering the implications of actual deployment."
Join us Wednesday an Noon Eastern Time for the latest data and solutions in managing multiple SOA implementations in our Webinar, Identifying and Federating Today's SOA Power Centers Through Enterprise Service Buses.
