VMware vSphereUpdate Manager automates patch management and eliminates manual tracking and patching of vSphere hosts and virtual machines. It compares the state of vSphere hosts with baselines, then updates and patches to enforce compliance.
Step 1: Install update manager into vCenter Server

VMware DRS dynamically balances computing capacity across a collection of hardware resources aggregated into logical resource pools, continuously monitoring utilization across resource pools and intelligently allocating available resources among the virtual machines based on pre-defined rules that reflect business needs and changing priorities. When a virtual machine experiences an increased load, VMware DRS automatically allocates additional resources by redistributing virtual machines among the physical servers in the resource pool.
Create DRS Cluster
Step 1: Edit Settings

VMware vSphere Fault Tolerance (FT) provides continuous availability for applications in the event of server failures by creating a live shadow instance of a virtual machine that is always up-to-date with the primary virtual machine. In the event of a hardware outage, vSphere FT automatically triggers failover—ensuring zero downtime and preventing data loss.
After failover, vSphere FT automatically creates a new, secondary virtual machine to deliver continuous protection for the application.
Step 1: Prepare VM
CD-ROM should attached to client device and device mood in to pass through CDROM

Manage HA Slot Size
Step 1: Set Admission control policy as define failover capacity by static number of hosts

VMware HA will works on a cluster that running at least two ESXi hosts in a situation host failure, without failing VMs that runs on that Host. (Depend on the available cluster resources after a host failure will not run all the VMs, therefore you can priorities most impotent VMs that should run in a situation like this)
Step 1: Setup a Cluster

In vSphere Alarm can be use to monitor for a condition or event, you can create conditions for your VMs and Hosts or can check events of a VM. When Alarm occur you can acknowledge them and also you can disable alarms.
Create an Alarm that monitor for a Condition
Step 1: Create an alarm and select monitor type as “Virtual Machine”

Vmware vApp is like a resource pool that contain more than one VM. vApp can use to setup a sequence for few VM to make power on by just power on the vApp.
Step 1: Create a vApp

Add an active directory user to Vcenter server and assign permission to allow and deny some task with creating a user role.
Step 1: Add a new role with all privilege

You can create resource pools on a ESXi server to allocate resources from a ESXi server to VMs by adding them into a resource pool.
Two VMs currently running on same speed with using same resources.

VMware vSphere live migration allows you to move an entire running virtual machine from one physical server to another, without downtime. The virtual machine retains its network identity and connections, ensuring a seamless migration process.
Transfer the virtual machine’s active memory and precise execution state over a high-speed network, allowing the virtual machine to switch from running on the source vSphere host to the destination vSphere host. This entire process takes less than two seconds on a gigabit Ethernet network.
- Automatically optimize virtual machines within resource pools.
- Perform hardware maintenance without scheduling downtime or disrupting business operations.
- Move virtual machines away from failing or underperforming servers.
