SDN Subscriptions have been at the centre of my attention for a while now (click here for previous posts). Monday’s news about price cuts for SAP’s Netweaver Subscription package reminded me of a little interview I’ve been meaning to do for ages with Stefan Ressing, a SAP Netweaver Solution Architect. Stefan is an old friend and former colleague of mine and I knew that Stefan had recently extended his subscription, so I wanted to know what his experiences so far have been.
