The document discusses the shift from server-centric to application-centric operations in IT, particularly with the rise of cloud computing. It highlights the essential characteristics of cloud services, including on-demand self-service and resource pooling, and emphasizes the need for new operational designs rather than traditional server management. The author, James Urquhart, stresses the importance of adapting to this new paradigm in the realm of IT operations.
