1. Introduction to vSphere

VMware released the successor to Virtual Infrastructure 3 (VI3) in May 2009 with a new name, vSphere, and a new version number, 4.0. This release introduces many new features, both small and large, which we will cover in this chapter. However, don’t be intimidated by all the new features. Overall, the core product is basically the same, so many of the things you know from VI3 will also apply to vSphere.
