An example method to provide fault tolerance in a virtualized computing environment with a first host in a first fault domain and a second host in a second fault domain may include determining whether a primary virtualized computing instance and a secondary virtualized computing instance are both in the first fault domain. The secondary virtualized computing instance may be configured as a backup for the primary virtualized computing instance and supported by the first host. The method may further include: in response to determination that the primary virtualized computing instance and secondary virtualized computing instance are both in the first fault domain, selecting, from the second fault domain, the second host based on comparing a resource availability of each of a plurality of hosts that include the first host and the second host; and migrating the secondary virtualized computing instance from the first fault domain to the second fault domain.

Providing fault tolerance in a virtualized computing environment through a swapping approach

An example method is described to provide fault tolerance in a virtualized computing environment with a first fault domain and a second fault domain. The method may comprise determining whether a first primary virtualized computing instance and a first secondary virtualized computing instance are both in the first fault domain. The method may comprise: in response to determination that the first primary virtualized computing instance and first secondary virtualized computing instance are both in the first fault domain, selecting a second secondary virtualized computing instance from the second fault domain; migrating the first secondary virtualized computing instance from a first host to a second host; and migrating the second secondary virtualized computing instance from the second host to the first host, thereby swapping the first secondary virtualized computing instance in the first fault domain with the second secondary virtualized computing instance in the second fault domain.
