Comparing utility and warranty of services

A system for comparing utility and warranty of services in an information technology (IT) stack comprising a plurality of layers, at least one of the plurality of layers having a set of services, the system comprising:

• at least one processing unit;
• memory operably associated with the at least one processing unit;
• and
• a utility and warranty tool storable in memory and executable by the at least one processing unit, the utility and warranty tool comprising:
• a determination component configured to:
• calculate, at each layer of the IT stack, a required utility and warranty (RUW) value for each of the set of services, by starting with an end user layer at a top hierarchical layer of the IT stack and continuing towards a data center layer of the IT stack, wherein the RUW value is determined from component availability, wherein the RUW value represents a desired solution for implementing a business process;
• and
• calculate, at each layer of the IT stack, an available utility and warranty (AUW) value for each of the set of services by starting with the data center layer of the IT stack and continuing towards the end user layer of the IT stack, wherein the AUW value is determined from component availability, wherein the AUW value is a measure of an ability of each of the set of services to satisfy the RUW value at each layer of the IT stack;
• a comparison component configured to compare the RUW value against the AUW value at each layer of the IT stack to determine whether each of the set of services satisfies the desired solution for implementing the business process;
• and
• instructions stored in the memory, which when executed by the processing unit, causes the system to modify one or more components of the IT stack when the comparison determines that each of the set of services does not satisfy the desired solution for implementing the business process.

A computer-readable hardware storage device storing computer instructions, which when executed, enables a computer system to compare utility and warranty of services in an information technology (IT) stack comprising a plurality of layers, at least one of the layers having a set of services, the computer instructions comprising:

• calculating, at each layer of the IT stack, a required utility and warranty (RUW) value for each of the set of services, by starting with an end user layer at a top hierarchical layer of the IT stack and continuing towards a data center layer of the IT stack, wherein the RUW value is determined from component availability, wherein the RUW value represents a desired solution for implementing a business process;
• calculating, at each layer of the IT stack, an available utility and warranty (AUW) value for each of the set of services by starting with the data center layer of the IT stack and continuing towards the end user layer of the IT stack, wherein the AUW value is determined from component availability, wherein the AUW value is a measure of an ability of each of the set of services to satisfy the RUW value at each layer of the IT stack;
• comparing the RUW value against the AUW value at each layer of the IT stack to determine whether each of the set of services satisfies the desired solution for implementing the business process;
• and
• when the comparison determines that each of the set of services does not satisfy the desired solution for implementing the business process, modifying one or more components of the IT stack.
