What is HA?
HA typically stands for High Availability. It refers to a system design approach that aims to minimize downtime and ensure continuous operation, even in the event of component failures. This is commonly achieved through redundancy, failover mechanisms, and monitoring to automatically switch to a backup system or component when a failure is detected.
What other technologies are related to HA?
HA Competitor Technologies
DR
Disaster Recovery is an alternative for ensuring uptime and recovery. While HA ensures VMs stay available in a single location, DR ensures VMs are available in a different location in the event of a site failure.
SRM
SRM (Site Recovery Manager) is a disaster recovery solution that automates failover to a secondary site, providing an alternative to HA for business continuity.
HA Complementary Technologies
DRS
DRS complements HA by providing initial placement and ongoing resource balancing, while HA focuses on restarting VMs after a failure.
vMotion
vMotion allows live migration of VMs, reducing downtime for planned maintenance and complements HA's role in unplanned downtime.
FT
Fault Tolerance provides continuous availability with a secondary VM running in lockstep, and can be used in conjunction with HA. FT protects from failures with zero downtime, while HA provides automated restart of affected VMs.
