Adaptive network provisioning

A system having a memory and one or more computer processors, the system configured to:

• determine that a physical infrastructure is updated, resulting in an updated physical infrastructure;
• determine, in accordance with the determination that the physical infrastructure is updated, active configuration information for configuring the updated physical infrastructure to provision a virtual network;
• obtain historical configuration information for configuring the physical infrastructure to provision the virtual network, wherein the historical configuration information is generated based on a configuration template;
• determine differential information between the active configuration information and the historical configuration information;
• and
• update the configuration template based on the determined differential information, wherein the updated configuration template comprises an updated mapping between virtual entities in a virtual resource pool and physical entities for the updated physical infrastructure.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a server to cause the server to perform a method, the method comprising:

• determining that a physical infrastructure is updated, resulting in an updated physical infrastructure;
• determining, in accordance with the determination that the physical infrastructure is updated, active configuration information for configuring the updated physical infrastructure to provision a virtual network;
• obtaining historical configuration information for configuring the physical infrastructure to provision the virtual network, wherein the historical configuration information is generated based on a configuration template;
• determining differential information between the active configuration information and the historical configuration information;
• and
• updating the configuration template based on the determined differential information, wherein the updated configuration template comprises an updated mapping between virtual entities in a virtual resource pool and physical entities for the updated physical infrastructure.
