How It Works

The Incapsula global CDN serves as a gateway for all incoming application layer traffic, which is then balanced among multiple data centers to ensure optimal performance. Rerouting occurs on the CDN level and is free of TTL-induced delays.

Real-time monitoring and control options provide a high degree of flexibility, including the option to set up geolocation-based rules to assist with compliance and other business goals.

How It Works

End-to-End Visibility

Incapsula provides live visibility into all requests as they travel from a visitor's device to your server. A detailed view of application traffic, both at the data center and server levels, enables us to automate decision making.

Multiple Distribution Methods

Incapsula GSLB supports advanced distribution methods, including:

  • Best connection time – Traffic routes are selected through a periodic sampling of server response times.
  • Geo-targeting – Traffic routes are based on visitor geolocation, with an option to redirect to another data center in case of failover.

Health Monitor and Global Failover

Continuous health and performance monitoring ensures the availability of your web servers and data centers.

Health monitoring is performed using the following mechanisms:

  • Passive monitoring based on server responses.
  • Active monitoring that proactively issues health check requests to web servers.

For additional control, user-configurable parameters and sensitivity thresholds allow for the creation of custom failover policies. The service can even monitor specific web resources and individual URL availability.
