Welcome

Welcome to our blog about all kind of topics that are related to software development. We blog about:

SOA, BPM, EDA, ECM and all the other buzz words. Beware some post might not be so common as you think. We are not scared to go against main stream thoughts.

Technologies like java, maven, springframework, OSGi and front end technologies and frameworks like jQuery, DWR, Flex.

Bring some stability to your architecture

By Allard, on October 30th, 2008

Applications have to run in high-consequence environments. They have to serve hundreds of thousands of users 24 / 7. Our clients spend millions in hard- and software and highly depend on the revenue generated by these applications. Unnecessary outage of these application is fatal.
Software Architects play an important role in setting up an architecture that [...]

Why are web services so different from an HTML user interface?
