Assessment and rationalization of resiliency of data center strategies

A computer readable storage medium storing a program of instructions executable by a machine to perform a method of assessing resiliency of facility configuration strategies, comprising:

• determining organization environment factors;
• determining one or more desired performance metrics associated with the organization;
• receiving a technical model specification that defines configuration for facilities of the organization;
• creating a Generalized Semi-Markov process representation of the configuration;
• solving, by a processor, for steady-state characteristics of the created Generalized Semi-Markov process representation;
• and
• estimating one or more values respectively of the desired performance metrics based on said steady-state characteristics,
• wherein said resiliency is measured based on said estimated one or more values.
