Cloud computing adoption continues to expand as the overall benefits of cloud (cost efficiency, self-service, and IT standardization) are becoming more broadly recognized. While private cloud is the primary type of cloud infrastructure that is in use today, organizations are finding that cloud can no longer be a standalone IT sourcing and consumption model. Enterprises demand greater flexibility and scalability, leading them to invest in hybrid cloud models, which supply them with a seamless application, data, and management environment across all of their IT resources. IDC expects that the percentage of users who adopt private or public cloud models will diminish over the next several years, as enterprises increasingly choose to implement a hybrid cloud model.
