Global online betting company bet365 has built extra resilience into its network with a new virtualisation system.
The company has upgraded its data network with new Cisco Nexus switching systems along with Overlay Transport Virtualisation (OTV) designed for distributed data centres.
The upgrade to OTV means that bet365 can have geographical separation of its operations, with server clusters split across more than one site. This helps ensure service continuity to customers and makes future upgrades possible without any downtime.
The firm said OTV complements its recent investment in a dedicated national fibre network.
"The low latency network is fully exploited by OTV allowing us to have database cluster nodes housed in different locations, and to upgrade and update them all in near real-time without service interruption,” said Neil Selby, head of networks and security at bet365.
“For instance, we could have half our servers in Manchester and half in Stoke, and as far as the network is concerned they are in the same building,” Selby said.
To help ensure continued service, in the event of a network failure or other catastrophe, the company has four separate datacentres, located at Stoke-on-Trent, Manchester, Heathrow and the City of London, with key computer equipment replicated against failure and capable of switching services and traffic between centres.
In a typical day bet365 may have traffic averaging one to two gigabytes per second, but with regular peaks in excess of 10 gigabytes per second in microbursts typically caused by sporting activity, said the firm.
In other network resilience news, the Greater London Authority (GLA) is using network emulation software to ensure the resilience of its web and networked applications across the organisation. The GLA has deployed iTrinegy’s INE for Windows system to run performance tests on applications so that users receive a good network experience.
