System and method for designing a logical model of a distributed computer system and deploying physical resources according to the logical model

A method comprising:

• constructing an application for a distributed computer system according to a logical model, the logical model having multiple components representing logical functions of the application;
• monitoring operation of the application during runtime;
• and
• automatically deploying resources of the distributed computer system to the application as operation conditions change.

• a first structure to store module information pertaining to one or more module instances of the module that correspond to physical resources used to implement the functional behavior represented by the module;
• a second structure to store port information pertaining to one or more port instances of the port;
• and
• a third structure to store wire information pertaining to one or more wire instances of the wire.
