All these problems will result in low reliability of the current system. Therefore, this paper raises a reliability evaluation of cold and hot backup system based on multiple-valued decision diagram algorithm. When designing the evaluation interval, this paper proposes a method to evaluate the system reliability from T to T + 1 period by separating the prediction time interval, which can effectively improve the accuracy of the evaluation method. According to current service concurrency, the quantity of VM in operation mode is adjusted. Under this premise, the number of cold and hot modes should be reasonably allocated to ensure the reliability of the whole system on the basis of meeting the reliability requirement R.
