Free Your Applications

Compose your own light-weight runtime that replaces the traditional application server

FreeYourApps.png Transaction management has traditionally been exclusive to large, somewhat monolithic application containers like application servers or mainframes. Back in 2006 already, we were the industry's first to move the other way, towards embeddable transaction management - and invented JEE without application server. Ever since then, lean and self-contained applications have been the central theme in everything we do. Fire the app server, keep the transactions!
