Associating virtual IP address of virtual server with appropriate operating system in server cluster

Abstract:

According to one or more embodiments, a computer implemented method includes receiving, by an operating system of a computer server, a request to execute an instance of a computer application. The method further includes deploying a virtual container for the instance of the computer application, the virtual container is allocated a dynamic virtual interne protocol address (DVIPA). The method further includes instantiating an application instance of the computer application in the virtual container. The method further includes, based on a determination that the computer application is a non-native application for the operating system, creating for the virtual container, a virtual network interface card (NIC) that translates network communication between the application instance and a physical NIC of the computer server. The method further includes selecting, by the virtual NIC, a communication protocol stack, from multiple communication protocol stacks, to bind the application instance for transferring the network communication.
