In today’s digital and always-on culture, businesses need to continue to operate 24/7/365. When downtime is not an option and your recovery time objective (RTO) is measured in seconds & minutes, you need to take a serious look at a serious solution, ‘high availability’.
High availability (HA) refers to systems and solutions that are durable and which are likely to operate continuously, without failure for a long time. The term implies that a system has accommodations for failure in the form of redundant components and can recover from software or hardware failure automatically. The more transparent that failover is to users, the higher the availability of the system.
