Method and apparatus for enhanced design of multi-tier systems

摘要

A system and method for performing enhanced modeling of multi-tiered architectures is presented. The system and method enable selection of a preferred design for a multi-tiered architecture of components based on a set of established criteria, and may employ certain vectors and functions in component attributes, and such attributes may include scalability and scope of fault attributes.

1. A method for representing multi-tier service attributes to be used in judging performance and availability of at least one service and costs associated with the at least one service, comprising:
performing, in a processor steps of,
listing at least one tier;listing candidate resource types usable in the at least one tier; andlisting a service tier characterization for each candidate resource type, wherein said service tier characterization comprises at least one from a group comprising:an ordered set specifying a valid number of resource instances in the at least one tier;a performance characterization;a scalability attribute; anda scope of fault attribute.
