Software and firmware updates are a fact of life in today's IT departments. Most organizations recognize that software updates are necessary to correct problems or flaws, to address security-related vulnerabilities, and to add new features. Fortunately, VMware offers a tool to help centralize, automate, and manage these patches for vSphere. This tool is called vSphere Update Manager (VUM). The remainder of the vCenter Support Tools assist in centrally deploying and managing hosts.
