Abstract
A computer-implemented method and system for providing an automatic recovery of at least one service chain including interlinked virtual functions of a cloud computing system is provided. One method includes generating backups of the virtual machines on which virtual functions of the service chain are deployed to provide snapshot states of the respective virtual machines. The method further includes monitoring a status of resources of the compute nodes hosting the virtual machines on which virtual functions of the service chain are deployed to detect failed resources of the compute nodes. The method further includes allowing over-allocation of resources and performing a repositioning of virtual machines on which virtual functions of the service chain are deployed from the detected failed resources to other working resources of the compute nodes of the service chain and initializing the repositioned virtual machines of the service chain to their last snapshot states.
