ABSTRACT

A2LL, the German social services and unemployment software system, was developed over the course of several years by T-Systems, a software department of the state telecommunications company, along with ProSoz, a smaller company of about 30 developers located in the town of Herten. The final product was delivered in the last quarter of 2004 and went live on January 1, 2005. The system consisted of the web browser front end, and the back end was based on 16 servers with four processors each.
