SOA Specs Visualized
In a previous blog post, I listed a number of SOA Specs and Security Specs that I thought were important to be familiar with when working with DataPower and other SOA technologies. In this post, I made a quick (and dirty) Visio diagram that I tend to draw up on a whiteboard when I’m at a new client…

JBoss/PicketLink WS-Trust Client and Third-Party Security Token Services
Another use-case that I touched on during my JBoss World 2012 presentation was using the PicketLink WS-Trust Client implementation to communicate with third-party Security Token Services. In particular, we discussed how the PicketLink SAML2STSIssuingLoginModule can communicate with the IBM Tivoli…

Protocol Transformations
Previously, I wrote a Wire Protocols post that outlined the common protocols that I’ve encountered when working with ESBs and SOA technology-especially DataPower. A primary function of an ESB is to provide the ability to convert service requests between these different protocols in a mostly…

From a technical stand point, a service is a program that takes some type of input, performs a task, and return some type of output. This is vague. It can describe…

Service Mediation vs. Service Orchestration
I’ve wanted to define this term for a while, but, someone beat me to it several years ago. I generally agree with what these guys have to say. These terms are still in use today at client sites where DataPower and the IBM SOA stack is being deployed. Service Mediation logic is the application of…
