I’ve been involved with cloud IT for over 12 months and I am still impressed at how the services just run; no fuss, no hassle, they just run. Sure there has been one outage with the Nuage hosted email service (I guess that’s why service levels are at 99.9% rather than 100%), when the data centre lost power, but within 20 minutes, it was back up and running. The Nuage file server is similarly humming along. However the most gratifying service level is to do with Nuage’s voice over ip (VOIP) service. The VOIP service is, I think, the one that relates to people’s emotions more than the others. The reason for this is that the others are managing data, whereas with VOIP, you are speaking with another person in real time, possibly a customer, and the last thing you want is for the call to be poor quality, or to drop out mid-stream. That’s why we’re really pleased that the Nuage VOIP service has been running without any hitch or complaint so far, and hopefully will continue.
