The Desired State is the state of your environment that assures application performance while achieving efficient use of resources and complying with business rules and constraints.
Instead of responding after a threshold is crossed, Turbonomic analyzes operating conditions and constantly recommends actions to keep the entire environment within the desired state.
You can measure performance as a function of delay, in which zero delay gives the ideal Quality of Service (QoS) for a given service. You can measure efficiency as a function where 100% utilization of a resource is the ideal. You can plot the relationship between delay and utilization as a curve. Up to a point, as you increase utilization, the increase in delay is slight. There comes a point on the curve where a slight increase in utilization results in an unacceptable increase in delay. On the other hand, there is a point in the curve where a reduction in utilization doesn’t yield a meaningful increase in QoS. The desired state lies within these points on the curve.
