This presentation discusses moving enterprise IT to public cloud. It notes that enterprise IT organizations face complex environments, growing costs, and lack of resources. The cloud looks like an option to help address these issues and generate business advantage. While there are challenges with cloud adoption related to security, control, and trust, the presentation argues that cloud providers may offer greater availability, security, and efficiency than traditional IT environments through their large scale operations. It advocates a hybrid approach for enterprises, moving commodity services to public cloud while using private cloud for high value services and legacy systems, with a goal of saying goodbye to legacy over time.
