Technology Landscape: Common Services

• A product independent architecture is enforced using carefully selected standards

• The selected OSS are not being used simply because they are open source, but because they are amongst the best solutions in each area

• Furthermore, maintaining a commercially supported open source alternative alleviates the single vendor reliance and provides a negotiating advantage

A note regarding the risks of using OSS

A common misconception regarding the risks of using OSS is that there is a lack of appropriate support services

We have commercial support contracts in place for every OSS product we use (RedHat/JBoss, Intalio, Alfresco)

The support we receive for the OSS products is not inferior to the respective support we receive for our commercial products
