Abstract: Methods and terminal devices, including computer programs encoded on computer storage media, for selecting a server node. According to one of the methods, a terminal device first sends a connection request to one server node, and then sends a connection request to another server node after a time interval T. The terminal device first sends a connection request to a first server node. If the terminal device receives, within a first preset duration T, response information fed back by the first server node, the terminal device does not need to send a connection request to another server node. This helps save resources. In addition, the terminal device may establish a connection to a server node corresponding to received response information, and does not need to wait for feedback from another server node. This helps reduce a delay in establishing a connection between the terminal device and a server node.

Abstract: Approaches presented herein enable generation of a multi-dimensional tag metric in a cloud resource management environment. More specifically, a tagging namespace is provided for managing a resource in the cloud resource management environment. This namespace comprises at least two dimensions and a plurality of positions. A set of tags associated with the resource are received into the tagging namespace. A match of each tag of the set of tags to a position within the namespace into which that tag was received is verified and an alert is triggered in the case verification fails. Alternatively, in the case verification is successful, the tag-containing namespace is validated as a multi-dimensional tag metric.
