1. A method performed by a physical computing system for modeling services of a cloud computing system, the method comprising: assigning, with said physical computing system, a unique index value from a number sequence to a number of objects of said cloud computing system; creating, with said physical computing system, a number of configuration values, each configuration value being based on a combination of said index values, each configuration value representing a unique combination of said objects associated with said cloud computing system; and associating, with said physical computing system, a number of sub-index values to each said configuration value, said sub-index values being based on a characteristic of said unique combination of said objects indicated by said configuration value.
