Automated orchestration of a virtualized computing environment

A method for automated orchestration of complex server provisioning tasks, the method comprising:

• a virtualized-environment orchestration system identifying a set of orchestration methods, where each orchestration method of the set of orchestration methods specifies a generic task of a set of generic tasks that must be performed in order to build a requested virtualized environment;
• the virtualized-environment orchestration system instantiating each orchestration method of the set of orchestration methods as a distinct runlist task,
• where a first orchestration method of the set of orchestration methods is instantiated as a distinct runlist task by embedding at least one placeholder variable into the first orchestration method,
• where each placeholder variable identifies a storage location of a corresponding data element required by the first orchestration method, and
• where values cannot he assigned to the embedded placeholder variables until the time when the virtualized environment is being built;
• the virtualized-environment orchestration system compiling the distinct runlist tasks into an orchestration runlist, where the orchestration runlist comprises instructions for building the entire virtualized environment, and where the runlist sequences the runlist tasks in an order determined by the set of generic tasks;
• and
• the virtualized-environment orchestration system assigning a value to each placeholder variable at the time when the virtualized environment is being built.

A computer program product, comprising a computer-readable hardware storage device having a computer-readable program code stored therein, the program code configured to be executed by a virtualized-environment orchestration system comprising a processor, a memory coupled to the processor, and a computer-readable hardware storage device coupled to the processor, the computer-readable storage device containing program code that, when run by the processor via the memory, implements a method for automated orchestration of complex server provisioning tasks, the method comprising:

• the virtualized-environment orchestration system identifying a set of orchestration methods, where each orchestration method of the set of orchestration methods specifies a generic task of a set of generic tasks that must be performed in order to build a requested virtualized environment;
• the virtualized-environment orchestration system instantiating each orchestration method of the set of orchestration methods as a distinct runlist task,
• where a first orchestration method of the set of orchestration methods is instantiated as a distinct runlist task by embedding at least one placeholder variable into the first orchestration method,
• where each placeholder variable identifies a storage location of a corresponding data element required by the first orchestration method, and
• where values cannot be assigned to the embedded placeholder variables until the time when the virtualized environment is being built;
• the virtualized-environment orchestration system compiling the distinct runlist tasks into an orchestration runlist, where the orchestration runlist comprises instructions for building the entire virtualized environment, and where the runlist sequences the runlist tasks in an order determined by the set of generic tasks;
• and
• the virtualized-environment orchestration system assigning a value to each placeholder variable at the time when the virtualized environment is being built.
