System and method for automatically triggering the live migration of cloud services and automatically performing the triggered migration

A method comprising the steps of:

• providing, by a cloud server system, a plurality of cloud services through processes running over a set of virtual machines hosted on the cloud server system;
• monitoring, by a client computer system, at least one monitored virtual machine, wherein the at least one monitored virtual machine is among the set of virtual machines operating on the cloud server system and the step of monitoring includes at least retrieving, by the client computer system, status data related to an operation of the monitored virtual machine from the cloud server system;
• assigning, by the client computer system, a priority level for at least two of the plurality of cloud services;
• detecting, by the client computer system, an anomaly indicative that the cloud server system is facing a disruption, wherein the step of detecting is performed using status data retrieved from the cloud server system;
• in the event an anomaly is detected, selecting, by the client computer system, a set of selected cloud services to be migrated, wherein said set of selected cloud services is among the set of cloud services operating on the cloud server system and the step of selecting includes at least associating a priority value with each of a plurality of candidate cloud services in the set of cloud services and weighing a migration memory cost for each of a plurality of candidate virtual machines such that the priority value for the set of selected cloud services, collectively, is maximized while the migration memory cost for the set of selected virtual machines, collectively, does not exceed a given threshold;
• and
• target selecting, by the client computer system, a destination host for the set of selected cloud services to be migrated to, wherein the step of target selecting is performed using status data retrieved from the cloud server system.

A system comprising:

• a cloud server to provide a plurality of cloud services through processes running over a set of virtual machines hosted on the cloud server such that each of the plurality of cloud services is associated with at least one of the virtual machines in the set of virtual machines;
• a server virtual machine (VM) monitor integral with said cloud server to monitor each virtual machine in the set of virtual machines hosted on the cloud server system;
• a client device communicatively coupled to said cloud server over a computer network;
• a client virtual machine (VM) monitor integral with said client device to collect and store data relating to each virtual machine in the set of virtual machines hosted on the cloud server;
• an anomaly detector integral with said client device to use data collected and stored by the client virtual machine (VM) monitor to determine when the cloud server is facing a disruption;
• a cloud service selector integral with said client device to select a set of selected cloud services to be migrated by at least associating a priority value with each of a plurality of candidate cloud services in the set of cloud services and weighing a migration memory cost for each of a plurality of candidate virtual machines such that the priority value for across the set of selected cloud services, collectively, is maximized while the migration memory cost for the set of selected virtual machines, collectively, does not exceed a given threshold, wherein said set of selected virtual machines is among the set of virtual machines hosted on the cloud server.
