High Availability (HA)
Ensuring maximum uptime and reliability is critical for web application security. FortiWeb offers multiple High Availability (HA) configurations—Active-Passive, Standard Active-Active, and High Volume Active-Active—to achieve 99.999% service level agreement (SLA) uptimes. These HA modes ensure continuous security protection and traffic processing even during hardware failures or maintenance periods.
Choosing the Right HA Mode for Your Deployment
The choice of HA mode depends on the specific needs of your environment:
-
Active-Passive HA is ideal for organizations prioritizing reliability and simple failover protection.
-
Standard Active-Active HA is suited for environments requiring load balancing and increased processing capacity.
-
High Volume Active-Active HA is the best choice for high-performance applications where maximum throughput and low latency are critical.
