Server clustering, SAN-replication, email continuity services (such as Mimecast) and basic email protection services are all reliable methods of protecting your business should an interruption in service occur.
However, the development of server virtualisation has enabled the design of systems which can provide continuity for all server-based IT functions by allowing those functions to dynamically move to alternative hardware in the event of a failure.
At taylorcocks IT we deploy enterprise-level solutions at an affordable cost for small and medium sized businesses.
Please see virtualisation for more information. Alternatively why not contact us and we would be happy to discuss the many benefits of this solution.
