A method and associated system. In response to a request to deploy a virtual machine, a virtual machine resource usage pattern having attributes matching a subset of attributes in than ordered sequence of attributes is selected from at least one virtual machine resource usage pattern stored in a virtual machine resource usage pattern library, based on an ordering of the attributes in the ordered sequence of attributes, wherein the virtual machine resource usage pattern library stores usage patterns for virtual machines previously deployed. A node on which the virtual machine is to be deployed is selected, based on the selected virtual machine resource usage pattern, and additionally based on either available resources of the plurality of nodes or predicted runtime resource requirements of the virtual machine to be deployed. The virtual machine is configured for being deployed on the selected node. The virtual machine is deployed on the selected node.

Deploying a virtual machine in a computing environment

A method and associated system. In response to a request to deploy a virtual machine in a computing environment, a virtual machine resource usage pattern having attributes matching a subset of attributes in than ordered sequence of attributes is selected from at least one virtual machine resource usage pattern stored in a virtual machine resource usage pattern library, based on an ordering of the attributes in the ordered sequence of attributes, wherein the virtual machine resource usage pattern library stores usage patterns for virtual machines previously deployed. A node on which the virtual machine is to be deployed is selected, based on the selected virtual machine resource usage pattern and predicted runtime resource requirements of the virtual machine to be deployed based on historical running data of virtual machines. The virtual machine is configured for being deployed on the selected node. The virtual machine is deployed on the selected node.

A method and associated system. A request to deploy a virtual machine in a computing environment is received. The request identifies an ordered sequence of attributes that the virtual machine to be deployed includes. In response to the request, a virtual machine resource usage pattern having attributes matching a subset of attributes in the ordered sequence of attributes is selected, based on an ordering of the attributes in the ordered sequence of attributes. A node on which the virtual machine is to be deployed is selected from two or more nodes in the computing environment, based on the selected virtual machine resource usage pattern and predicted runtime resource requirements of the virtual machine to be deployed.

The present application provides a method and system for Cross Domain Single Sign On. The method comprises: receiving a request from a user to a service provider; processing the user request prior to relaying the request to the service provider; forwarding the processed request to the corresponding service provider according to the type of request; in response to receiving a response to the request from the service provider, processing the response, and forwarding the processed response to the user. By adopting the method and system of the present application, a Single Sign On management proxy is introduced as a united management system for a session lifetime of the user. The SSO management proxy manages operations of logging in, checking a session expiration and recovering, logging out, URL mapping, error processing, and access control, and effectively improves the availability, security, functional continuity of the service as well as the user's experience.
