Techniques for virtualized network capacity management

A non-transitory computer-readable storage medium having instructions which, when executed by one or more processors of a device, cause the device to implement a capacity manager module to perform operations for accurately determining available capacity in a virtualized resource infrastructure, the operations comprising:

• decomposing each capacity entity type of a plurality of capacity entity types available for provisioning in the virtualized resource infrastructure into a plurality of independent entity types provided by one or more capacity provider modules, wherein each of the plurality of capacity entity types corresponds to a virtualized resource or service, wherein each of the plurality of capacity entity types, when executed as an instance, utilizes one or more of the plurality of independent entity types, wherein each of the plurality of independent entity types do not depend upon others of the plurality of independent entity types;
• determining requirement data that includes, for each of the plurality of capacity entity types, a required amount of each of the plurality of independent entity types needed to provide the capacity entity types;
• receiving, from each of the one or more capacity provider modules, capacity messages including current availability information associated with those of the plurality of independent entity types provided by the capacity provider module, wherein the current availability information indicates amounts of those of the plurality of independent entity types that are able to be allocated or amounts of those of the plurality of independent entity types that are already allocated;
• and
• providing virtualized resource infrastructure availability information to a client, wherein the virtualized resource infrastructure availability information describes at least some of the plurality of capacity entity types and is generated based upon the current availability information and the determined requirement data determined.

A system, comprising:

• one or more capacity provider modules implemented by a first set of one or more computing devices;
• and
• a capacity manager module implemented by a second set of one or more computing, the capacity manager module comprising instructions that upon execution cause the capacity manager module to:
• decompose each capacity entity type of a plurality of capacity entity types available for provisioning in a virtualized resource infrastructure into a plurality of independent entity types provided by the one or more capacity provider modules, wherein each of the plurality of capacity entity types corresponds to a virtualized resource or service, wherein each of the plurality of capacity entity types, when executed as an instance, utilizes one or more of the plurality of independent entity types, wherein each of the plurality of independent entity types do not depend upon others of the plurality of independent entity types;
• determine requirement data that includes, for each of the plurality of capacity entity types, a required amount of each of the plurality of independent entity types needed to provide the capacity entity;
• receive, from each of the one or more capacity provider modules, a capacity message including current availability information associated with those of the plurality of independent entity types provided by the capacity provider module, wherein the current availability information indicates amounts of those of the plurality of independent entity types that are able to be allocated or amounts of those of the plurality of independent entity types that are already allocated;
• and
• provide virtualized resource infrastructure availability information to a client, wherein the virtualized resource infrastructure availability information describes at least some of the plurality of capacity entity types and is generated based upon the current availability information and the requirement data determined.
