In this post, I discuss the new features and how we can utilize them to simplify the management of your virtual infrastructure. vSphere Lifecycle Manager introduces many new features that simplify the process of managing not only ESXi patching but also the full firmware lifecycle of the ESXi host’s hardware. With the release of vSphere 7.0, VMware has not only added new functionality to the Update Manager Server but has rebranded this great tool as vSphere Lifecycle Manager (vLCM). However, the core functionality of Update Manager hasn’t changed much since the original 1.0 release. Since then, VMware has made numerous changes to Update Manager Server in some cases, introducing new features, while also removing features (guest operating system and application patching). This new solution was titled VMware Update Manager (VUM) Server. To simplify virtual infrastructure management, in 2007, VMware introduced a new feature with VMware VirtualCenter Server 2.5 that automated these processes. This process included manually staging patch files as well as executing install and reboot commands to each ESX host. In the early days of VMware ESX and VirtualCenter Server (now called vCenter Server), patching and upgrading ESX hosts was a manual and challenging task that required a significant amount of time from a virtual administrator to complete.
