High availability is an important subset of reliability engineering, focused towards assuring that a system or component has a high level of operational performance in a given period of time. At a first glance, its implementation might seem quite complex; however, it can bring tremendous benefits for systems that require increased reliability. A high availability system must have sound data protection and disaster recovery plans. An absolute must is to have proper backups. Another critical thing is the ability to recover in case of a data loss quickly, corruption, or complete storage failure. Best practices for high availability From an enterprise IT perspective, downtime maps directly to lost revenue streams and dissatisfied users.

Log-Shipping Standby Servers High availability (HA) allows you to place two firewalls in a group and synchronize their configuration. This prevents a single point of failure on your network. The two firewalls have a heartbeat connection, which ensures failover if one of the firewalls goes down. But high availability comes at a price. High quality components are more expensive, and making them redundant doubles the costs at least. Additional spare parts increase costs further.
