Method and apparatus for allocating resource

An apparatus for allocating a resource, comprising:

• at least one processor;
• and
• a memory storing instructions, wherein the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• extracting a resource category matching a target sub server and a required quota corresponding to the resource category from a request sent by a client side;
• determining a number of sub servers in a sub server group receiving the request;
• determining a globally available quota and a total limit matching the resource category;
• determining a limit matching the resource category in the target subserver based on the total limit and the number of sub servers;
• performing resource allocation for a resource quantity corresponding to the required quota of the request based on a comparison between the required quota and the limit of the target subserver;
• determining that a current quota of the globally available quota is smaller than the limit of the target subserver, wherein the globally available quota is a shared quota available for a plurality of subservers in the subserver group, and the limit of the target subserver is a local available quota in the target subserver;
• and
• decreasing the limit of the target subserver to a value equal to the current quota of the globally available quota, in response to determining that the current quota of the globally available quota is smaller than the limit of the target subserver.

A non-transitory computer readable medium, storing a computer program thereon, wherein the program, when executed by a processor, causes the processor to perform operations, the operations comprising:

• extracting a resource category matching a target sub server and a required quota corresponding to the resource category from a request sent by a client side;
• determining a number of sub servers in a sub server group receiving the request;
• determining a globally available quota and a total limit matching the resource category;
• determining a limit matching the resource category in the target subserver based on the total limit and the number of sub servers;
• performing resource allocation for a resource quantity corresponding to the required quota of the request based on a comparison between the required quota and the limit of the target sub server;
• and
• determining that a current quota of the globally available quota is smaller than the limit of the target subserver, wherein the globally available quota is a shared quota available for a plurality of subservers in the subserver group, and the limit of the target subserver is a local available quota in the target subserver;
• and
• decreasing the limit of the target subserver to a value equal to the current quota of the globally available quota, in response to determining that the current quota of the globally available quota is smaller than the limit of the target subserver.
