Interoute appreciate that different services require different service levels. Not all servers need to be fully resilient, and some services will need to be configured with a great deal of resilience. Likewise, some servers will need full monitoring and management and others will only need light monitoring or indeed no monitoring at all.
As a result, Interoute have a variety of service monitoring and management options. Customers can deploy services from whichever level is appropriate to the server/service being deployed.
