Two vital aspects of delivering a service in the cloud, such as Talis Prism 3, are to ensure that the service is available for a very high proportion of the time, and that it performs well. Naturally we monitor these closely, and now you can see the information directly from the monitoring service.

You’ll find the link to the Prism Service Availability monitor on the Talis Prism microsite in the left panel under Customer Resources.

The information is updated every five minutes. At the top there is a status indicator showing the current availability of the Prism 3 service.

The rest of the report shows uptime and average response time per month, most recent first, and you can select a month to see daily averages. Our target for uptime is 99.5% or better, so it is pleasing that the monthly average since February 2009 is 99.86% and that the last three complete months are all higher than that. We continue to strive to improve this further.

The montly average response times show an improving trend through 2010, during which twenty-four libraries went live with Prism 3, bringing the total to thirty-seven. This reflects the continuing effort to improve performance.

In addition to providing this information, we are working towards improved status information about Prism 3 on the Talis Live Services page.
