Abstract: Embodiments of the present invention relate to methods and apparatuses for enabling cluster scaling. Specifically, there is disclosed a method of recording a context of configuration for an initial node of a cluster, comprising: retrieving at least one file to be used for configuring the initial node; and recording a context while configuring the initial node using the at least one file, the recorded context being information on the configuration of the initial node and to be used for enabling addition of a new node into the cluster. There is also disclosed a method of enabling addition of a new node into a cluster. Corresponding apparatuses are also disclosed. According to embodiments of the present invention, the efficiency of improving cluster scaling may be effectively improved.

Abstract: A method of sharing virtual machine resources. The method includes: in response to at least one user logging in to the virtual machine, monitoring file operations taken by the user in the virtual machine; recording the types of file operations; in response to the user logging out from the virtual machine, restoring the virtual machine back to the original state at the time when the user logged in to the virtual machine according to the recorded types of file operations; and in response to receiving a request for virtual machine resources, assigning one of the virtual machines which is idle and restored back to the original state to the requesting user.
