Load Balancing Options
Incapsula supports a wide variety of load balancing methods to optimize traffic distribution across servers, maximizing application performance and reducing server load.
Users may choose from a range of sophisticated traffic distribution algorithms, with or without a “persistence override” option. Real-time server health and performance checks are used to rapidly detect outages and eliminate downtime. In the event of web server failure, Incapsula stops routing traffic to it. As soon as the web server resumes operation, traffic begins to be forwarded to it.
Automatic Site Failover
Incapsula’s service supports automatic failover between primary and secondary sites to enable high availability and accelerate disaster recovery.
As soon as Incapsula detects that the primary site has gone down, it automatically kick-starts your standby data center.
Application Delivery Rules
Rewrite, forward or redirect requests at your network edge. Provide different assets based on visit and request attributes, without changing the user-facing URL.
Global Server Load Balancer
Global Server Load Balancing (GSLB) for companies operating multiple data centers ensures high availability and consistent performance of applications and websites.
Leveraging a global CDN, Incapsula’s service supports both performance-based GSLB (i.e. user is assigned to data center with the best connection time) and geography-based GSLB (i.e. user is assigned to data center according to his geographic location).
By monitoring the health and performance of your web servers and data centers in real-time, Incapsula ensures that your application or website is accessible to users at all times.
Built-in real-time monitoring and notification capabilities ensure that traffic is always routed to a viable web server. Web server monitoring is performed using the following mechanisms:
According to responses from the web servers for actual traffic that is forwarded to them.
By proactively sending health check requests to the web server (particularly useful for low traffic websites)
Incapsula allows you to monitor all your traffic in real time and verify that your traffic is balanced correctly between the different servers.
Real time monitoring also allows you to identify and correct issues as they happen and before they have an impact on your websites.
