A computing resource management apparatus and method are provided. The computing resource management apparatus comprise, at least one processor configured to implement: a collector configured to collect an amount of computing resources used by each of a plurality of virtual network functions (VNFs) which are connected by service chaining; a detector configured to detect, from among the plurality of VNFs, a target VNF to be adjusted by respectively comparing computing resources used by each of the plurality of VNFs with computing resources allocated to each of the plurality of VNFs; and an adjustor configured to adjust computing resources allocated to the target VNF, and adjust computing resources allocated to a plurality of remaining VNFs, from among the plurality of VNFs, based on an adjusted amount of computing resources.
