SAP AG 2004, SAP TechEd / NW105 / 13

2. Decision: Distribution Options

SCS instance now always gets installed on the central instance host

So, only distribution option for one system is if you want to install a central system (CI + DB on one host) or a distributed system (CI and DB on different hosts)

Complexity reduced
