The invention provides a method for elastically scheduling resources. The method comprises the following steps: generating a pressure test file, wherein the pressure test file comprises an item to betested and test instance information; performing a pressure test according to the pressure test file; collecting performance data of a test instance in a test process according to the item to be tested and the test instance information; and monitoring and analyzing the performance data, and judging whether elastic capacity expansion and contraction adjustment is required according to the performance data. By adoption of the method provided by the invention, elastic capacity expansion demands can be quickly responded and stored, and resources are expanded and contracted in time to ensure the stable operation of the system.
