Described herein are systems, methods, and software to handle requests to an application file shared by a plurality of applications on a computing system. In one implementation, a method of handling request for an application file shared by a plurality of applications on a computing system includes identifying a request for the application file on the computing system, wherein each application in the plurality of applications is associated with an individualized version of the application file, and wherein the plurality of applications is stored on separate application storage volumes attached to the computing system. The method further provides identifying an application associated with the request, and identifying an application storage volume in the application storage volumes that stores the application. Once identified, the method also includes retrieving the application file from the identified storage volume to support the request.

Resolving conflicts of application runtime dependencies

A method to improve virtual desktop infrastructure (VDI) user experience includes providing a user access to a first virtual desktop executing a first set of applications and having a first virtual machine (VM) configuration, collecting VDI performance metrics associated with the first virtual desktop, detecting a problem from the VDI performance metrics, and changing a first remote display protocol configuration to address the problem. The method further includes collecting the user's feedback, training a model with the first VM configuration, the first set of applications, the user's feedback, and the first remote display protocol configuration, receiving a second VM configuration for a second virtual machine providing a second virtual desktop and a second set of applications on the second virtual desktop, using the model to generate a second remote display protocol configuration for the second virtual desktop, and configuring the second virtual desktop with the second remote display protocol configuration.

Solution which can improve VDI user experience automatically

A system can allow a user to continue using a virtual machine while a background reboot occurs on a clone of the virtual machine. A backup agent operating on a server can receive a request from a virtual machine operating in an active state, to complete a reboot operation without operational interruption. A hypervisor can clone the virtual machine. During and after cloning, the backup agent can cause a filter agent to capture changes to the virtual machine. The virtual machine clone can notify the backup agent that the reboot is complete. Changes made in the interim on the virtual machine can be integrated on the virtual machine clone. Then the hypervisor can transition usage from the virtual machine to the virtual machine clone.

Preventing interruption during virtual machine reboot

Techniques are disclosed herein for managing network bandwidth in a distributed system having multiple endpoints that upload data to a central server or server cluster. One embodiment provides a computer-implemented method that includes receiving a logical topology of the network that is determined based on network measurements. The method further includes generating a tree having links of the logical network topology as nodes, and allocating bandwidth during a traversal of the tree to obtain a bandwidth allocation scheme for the endpoints uploading data. In addition, the method includes controlling bandwidth consumption by the endpoints based on the determined bandwidth allocation scheme.

Reverse breadth-first search method for optimizing network traffic in a distributed system with a point of convergence

A method of rebooting a computing system in which a virtual machine (VM) runs on top of a hypervisor and a host operating system (OS) includes the following steps. Those steps are sending, from the host OS to the hypervisor, a pre-reboot notification that the host OS is going to reboot, in response to reception of the pre-reboot notification, saving by the hypervisor state of a session that is executing in the VM, rebooting the host OS, after the host OS is rebooted, logging on to the host OS using a credential provider that was previously registered with the host OS and sending a post-reboot notification from the host OS to the hypervisor, and in response to reception of the post-reboot notification, instantiating by the hypervisor a VM in which the session is resumed using the saved state of the session.

Saving data for virtual machine (VM) sessions upon update of host operating system

Techniques are disclosed herein for managing network bandwidth in a distributed system having multiple endpoints that upload data to a central server or server cluster. One embodiment provides a computer-implemented method that includes collecting network measurements from traffic flows in a network over which the endpoints upload the data to the central server or server cluster. The method further includes determining a logical topology of the network based on the network measurements, and solving an optimization problem to determine a bandwidth allocation scheme for the endpoints uploading data, wherein capacity of links in the logical topology are constraints in the optimization problem. In addition, the method includes controlling bandwidth consumption by the endpoints based on the determined bandwidth allocation scheme.

Method and system for optimizing network traffic in a distributed system with a point of convergence

Techniques are disclosed herein for managing network bandwidth in a distributed system having multiple endpoints that upload data to a central server or server cluster. One embodiment provides a computer-implemented method that includes receiving a logical topology of the network that is determined based on network measurements. The method further includes resolving a convex optimization problem over the logical topology to determine a bandwidth allocation scheme for the endpoints uploading data. In addition, the method includes controlling bandwidth consumption by the endpoints based on the determined bandwidth allocation scheme.
