With more employees working from home and creating distributed and heterogeneous remote environments, IT uptime has become even more critical than before, said Krista Macomber, senior analyst at Evaluator Group. Automation plays a big role in maintaining that uptime, as failover for critical applications contains many moving parts, and it all must be executed quickly and correctly. There is definitely market demand for third-party software for HA and disaster recovery automation, Macomber said.
Although HA technology for critical applications is there, execution is still shaky, Macomber added. Application-driven availability tends to be handled in a very isolated manner, and vendors such as SIOS target the specific application user — not the IT team that, ultimately, has to implement the technology.
“This tends to create issues between application owners and IT operations due to the need to coordinate between them for updates or other changes. This coordination is challenging and tends to break down over time,” Macomber said.
However, DR orchestration and HA capabilities are starting to appear in core data protection offerings, Macomber said. Since these features are integrated into products IT administrators work more closely with, they hold greater appeal than a separate product tailored specifically to provide HA for one application.
