Epilog Like many of us, I'm a kind of addicted to Twitter. But a few weeks ago, the admins of my client cuts the connection to Twitter and all of the known anonymanizers like "agentanon". My hands began to tremble, my work became poorer and poorer (just a joke!). Two lucky circumstances: * first free weekend since many month * my SAP PRD server is already up and connected to the internet, because I have a presentation on Monday Why don't turn a problem into a challenge and develop my own "ABAP twitter client" ?

A pessimistic approach towards SOA seems to prevail in some blogs. But these opinions strike me by surprise. In the industries I am working for - public sector, healthcare and Defense/ public security - SOA is predominant and you will find only rare examples of tenders where SOA is not highlighted as the guiding principle for the whole architecture. SAP's CTO Vishal Sikka has already provided the community with some very helpful insights concerning these discussions. I just want to add some points from an architect's point of view: From my point of view it is not the SOA approach itself which should be questioned but the way how we architects sometimes work on SOA. Some of the mistakes that are listed below I have encountered during my SOA projects. Others are based on discussions with other architects and decision makers inside and outside SAP, from customers and from partners. My intention is simple: I want to help to avoid these mistakes in the future and to strengthen the SOA approach which is for me without an alternative.

Keep SOA as simple as possible!
