The invention discloses a method, device and system for delaying starting up of a cloud data center host computer, and belongs to the field of cloud computing system control. The method comprises the steps: starting the first host computer in the data center, then collecting load information of the cloud data center, and calculating the waiting time and expected starting up number of the next starting up control after analyzing the future demand quantity of the newly increased host computers, finally starting up the host computers. The method is capable of adequately considering the dynamic volatility of the system load, forecasting the rational starting up number and timing of the new host computer through tracking its tendency, and considering the performance and energy conservation. The method is capable of, according to the change tendency of each host computer load in the cloud data center, evaluating the demand degree of the future task load for the number of new host computers, making the variable control interval time, and enabling the system to respond the steady and sudden task load change in time.
