This document discusses transitioning to a software-defined datacenter (SDDC). It defines SDDC as decoupling infrastructure resources from consumers through abstraction, pooling resources across systems, and automating/orchestrating provisioning through programmable APIs. Benefits include optimization of pooled resources, increased agility, and lower costs. The transition involves gradual virtualization and automation of servers, storage, and networks. Additional resources are provided to help organizations develop roadmaps and plans to adopt SDDC technologies.
