Abstract
In a traditional deployment model the identity of a server depends on its hardware. Servers are unambiguously indentified by addresses like Media Access Control (MAC), Universally Unique Identifier (UUID), World Wide Node Names (WWNN), World Wide Port Names (WWPN), etc. defining together the “personality” of this server. Some of these elements can’t be changed. This makes it difficult to re-assign servers to other tasks in a cloud environment.
Innovative concepts like unified and stateless computing and service profiles enable full flexibility for SAP on public and private Cloud implementations. This chapter deals with the details of stateless computing and how it influences the organizational structure of SAP operations. We take also a look at containerized datacenters and block and pod concepts and close with the discussion about how “green” clouds can be.
