CONSISTENT PROVISION OF MEMBER NODE GROUP INFORMATION ON VIRTUAL OVERLAY NETWORK

Abstract:

A method, computer system, and computer program product for provisioning member node group information on a virtual overlay network in a multi-controller cloud environment are provided. The embodiment may include one of the controllers receiving a group association call from user interface for a target node, wherein the group message is either an association-add the target node to or association-remove the target node from a node group. The embodiment may also include the controller performing consistent database manipulation by updating a database based on the received association-add or association-remove call, wherein the controller first updates a database by adding or removing the target node to or from, respectively, the node group in the database. The embodiment may further include the controller reading out the updated member node group from the database before issuing a provision-create or a provision-remove request to the target node.
