<p>Provided is a method for guaranteeing quality of service (QoS) of a cloud application, including: an upper-layer scheduling module determining the virtual machines (VMs) corresponding to at least two processes of a cloud application according to a QoS policy and a QoS restraint parameter; sending the QoS policy and the QoS restraint parameter to a lower-layer scheduling module so that the lower-layer scheduling module determines a physical machine (PM) for creating the VMs according to the QoS policy and the QoS restraint parameter. Accordingly, also provided is a device, solving the problem that the QoS of an application cannot be ensured since the upper and lower-layer modules perform scheduling separately, improving the reliability of guaranteeing QoS.</p> |
