Digifonica has deployed a series of infrastructural provisions to ensure the redundancy of our network, hardware, software, data, and partner sites.
| | Network Redundancy | | | - Digifonica has four separate connections to our UK switching platform; two each from two independent vendors.
- Digifonica uses the BGP protocol to protect against losing connection with one provider by having the connection automatically fail over to the other provider.
- Digifonica has a main provider and a stand-by provider, providing two connections each. Having two connections from each provider protects us from having hardware failures since they are connected to separate switches.
- Digifonica's BGP protocol is configured and we have obtained our own IP addresses from IP Registrars. This is necessary for failover to take place.
| | Hardware and Software Redundancy | | | - All web services run on a number of servers. By this provision, we gain hardware redundancy and increase the amount of load the sites can handle. On a need basis, Digifonica can add additional hardware to further scale the load capacity of our partner sites.
- All databases are load balanced and replicated. Load balancing allows distributed request handling and provides redundancy and high-availability. Through replication, we have real-time copies of all databases for instant disaster recovery.
| | Partner Site Redundancy | | | - Using F5 load balancing servers, we are able to double the amount of hardware used to power partner websites. By doing so, we gain hardware redundancy and increase the amount of load the sites can handle. On a need basis, Digifonica can add additional hardware to further scale the load capacity of our partner sites.
