Fidessa achieves greater resiliency with automated business continuity resulting in increased QoS, resilience and diversity for Internet services.
Resilient Internet Connectivity for Business Continuity.
Therefore, the challenge Fidessa faced was automating as much of its BCP as possible. Among the many Financial Trading tools and services that Fidessa provides, one of them includes delivery of web-based services, such as its award winning fragmentation analysis tools.
The company required resilient infrastructure to deliver these services to the international trading community and required automated failover to its London office in the event of a fault with the service at the company’s head office in Woking.
The major problem Fidessa came across in trying to solve this challenge was that most providers did not have the technology or expertise necessary to provide automated failover in a BCP scenario.
After having dealt with a number of Internet Service Providers (ISPs), needing to change IP addresses because of relocations and to become more flexible in the delivery of its web-based services, Fidessa first realised it needed to obtain its own subnet of IP addresses. Secondly, the organisation realised that the provider for Internet connectivity would need to have Network reach combined with innovative technology and know-how to deliver an automated, seamless failover between Woking and London.
Two of the world’s largest communications providers were approached; however, Fidessa determined that neither organisation was flexible enough nor could they provide the type of failover desired to ensure minimum impact during a disaster. These providers required manual intervention and changes to Fidessa’s core Network for failover to occur between the Woking and London offices.
This was not ideal to fulfil the company’s Business Continuity plans - time and effort needed would be labour and resource intensive - taking away from where these resources could be used in a disaster situation.
At the start of the project Exponential-e helped by fulfilling the first requirement of obtaining Provider Independent (PI) IP addresses from RIPE NCC. To get Fidessa up and running quickly, a temporary subnet of Provider-Aggregatable (PA) IP addresses were provided by Exponential-e for the 100Mbps Internet connections installed at the primary office in Woking and the office in London. After RIPE NCC allocated Provider Independent (PI) IP addresses to Fidessa, Exponential-e smoothly facilitated the migration to the PI IP addresses from the temporary PA ones provided.
At the primary connection in Woking, a dynamic routing protocol was configured to be used during normal times. In the event of the primary connection failing, a floating, static route will automatically reroute the Internet traffic via the backup circuit in London.
The failover will then be managed by a Border Gateway Protocol (BGP) session, where a lower metric is configured at Woking, ensuring it is the primary route, and a higher metric is configured in London, ensuring it is only used if there is a fault with the service at Woking. However, both locations will still be able to send outbound traffic independently as needed.
