VMware vSphere Distributed Resource Scheduler

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.

VMware vSphere Fault Tolerance

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.

Using VMware vSphere High Availability (HA)

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)
