Method and apparatus for data storage service

A system, comprising:

• a data storage system including one or more processors and memory;
• and computer-executable program logic encoded in memory of one or more computers enabled to provide storage services, wherein the computer-executable program logic is configured for the execution of:
• receiving a storage service template from a user, the storage service template specifying a plurality of storage service policies for the user and a corresponding chained set of storage service functions for execution in a template-specified predetermined order, the storage service functions having respective data inputs and data outputs and being chained together such that the data output of a given storage service function is equal to mandatory data input requirements of a corresponding next successive storage service function;
• and
• providing the chained set of storage service functions according to the storage service template, the chained set of storage service functions being performed on data of the user to obtain processed user data accordingly, including intermediate data generated by corresponding storage service functions and provided as input to corresponding next successive storage service functions.

A computer program product for providing a storage service, the computer program product comprising:

• a non-transitory computer readable storage medium encoded with computer-executable code, the code configured to enable the execution of:
• receiving a storage service template from a user, the storage service template specifying a plurality of storage service policies for the user and a corresponding chained set of storage service functions for execution in a template-specified predetermined order, the storage service functions having respective data inputs and data outputs and being chained together such that the data output of a given storage service function is equal to mandatory data input requirements of a corresponding next successive storage service function;
• and
• providing the chained set of storage service functions according to the storage service template, the chained set of storage service functions being performed on data of the user to obtain processed user data accordingly, including intermediate data generated by corresponding storage service functions and provided as input to corresponding next successive storage service functions.
