  • Patent number: 9940210
    Abstract: Embodiments described herein are directed to migrating affected services away from a faulted cloud node and to handling faults during an upgrade. In one scenario, a computer system determines that virtual machines running on a first cloud node are in a faulted state. The computer system determines which cloud resources on the first cloud node were allocated to the faulted virtual machine, allocates the determined cloud resources of the first cloud node to a second, different cloud node and re-instantiates the faulted virtual machine on the second, different cloud node using the allocated cloud resources.

  • Patent number: 9928101
    Abstract: In an environment that includes a host computing system that executes virtual machines, and a secure cloud computing channel that communicatively couples the host to a client computing system that is assigned to a particular one of the virtual machines, the particular virtual machine generates a certificate, install the certificate on the itself, and returns a certificate representation to the client. This may occur when the virtual machine is provisioned. During a subsequent connection request from the client to the virtual machine, the virtual machine returns the certificate to the client. The client compares the certificate representation that was returned during provisioning with the certificate returned during the subsequent connection, and if there is a match, then the virtual machine is authenticated to the client. Thus, in this case, the virtual machine authenticates without the client having to generate, install, and manage security for a certificate.

  • Publication number: 20170024233
    Abstract: A virtual machine hosting environment executing on a physical machine is operable to instantiate a virtual machine that is capable of initiating I/O operations directed to a remote storage. The virtual machine hosting environment is operable to determine when an unavailability condition exists with respect to the remote storage and when such unavailability condition no longer exists. The virtual machine hosting environment is further operable to suspend the virtual machine based at least on the determination that the unavailability condition exists and to resume the virtual machine based at least on the determination that the unavailability condition no longer exists. The virtual machine hosting environment may be still further operable to save one or more pending I/O requests generated by the virtual machine in conjunction with pausing the virtual machine and to send the pending I/O request(s) to the remote storage in conjunction with resuming the virtual machine.

  • Publication number: 20160294930
    Abstract: Embodiments provide migration of services across different clusters to balance utilization and meet customer demands. Different service migration options may be performed with or without downtime. The artifacts of the service are moved to a new destination cluster. The service is created on the new destination cluster and staged so that the service is almost ready to start. In one embodiment, the service is stopped on the old cluster and started on the new cluster. After stopping the service, DNS is updated to point to the service on the new cluster. In another embodiment, the service is stopped on the old cluster and started on the new cluster with the same IP address to avoid DNS reprogramming and associated delays. In a further embodiment, the migration is performed without downtime by moving the service part by part from one cluster to another.

  • Patent number: 9436492
    Abstract: The provisioning of a virtual machine when booted from virtual storage. During virtual machine boot from an image, the virtual machine detects storage media. The virtual machine acquires a provisioning agent and provisioning data from the detected storage media. The virtual machine uses the provisioning data to provision itself, and executes the provisioning agent. The provisioning agent may monitor the progress of the provisioning and/or report a status of the provisioning. The virtual machine may operate in a cloud computing environment, the status of the provisioning agent being returned to the user through the cloud environment. The user need not generate the provisioning data in a format readable by the virtual machine. Instead, perhaps some naturally entered user input is used to automatically generate the properly formatted provisioning data using perhaps a service in the cloud.

  • Publication number: 20160070563
    Abstract: Methods, systems, and computer-readable media for deploying an updated image to nodes propagated throughout a distributed computing platform are provided. Upon receiving an indication to install a patch to an operating system residing on the nodes, an existing image of the operating system is accessed at a staging service. The staging service generates the updated image by applying the patch to the existing image. The process of applying the patch includes mounting the existing image of the operating system to a virtual machine, copying the patch to the mounted existing image, setting a command within the existing image that executes upon activating the virtual machine, and activating the virtual machine, thereby executing the command. This directs the patch to be installed. The updated image is pushed to the nodes. The nodes are configured to utilize the updated image as the operating system without performing an individual installation of the patch.

  • Patent number: 9262366
    Abstract: Software deployment to server nodes within large-scale networked systems is provided using image-based deployment. A mostly immutable image is provided at a central service and transferred from the central service to the server nodes. The image includes a base image, which is immutable, and a delta image, which is writable and provides role-specific and/or node-specific state to the base portion. When a server node receives an image from the central server, the server node stores the image intact without installation. The server node then runs software directly from the stored image.

  • Publication number: 20160006666
    Abstract: Tenant and server platform coordination of the performance of atomic tasks that are to be performed by the platform, but which have at least a potential impact on the tenant. The server platform allows a particular tenant a timeframe within which the tenant itself may approve of initiation of each of one or more tasks. The server platform may protect itself from delayed action by imposing time constraints on the timeframe such that after the timeframe is elapsed, the tenant no longer has control over triggering the initiation of the particular task. Accordingly, the tenant is provided with flexibility on controlling initiation of a task performed by the server platform, while the server platform maintains a level of control to protect its resources and balances the needs of the various tenants.

  • Patent number: 9229839
    Abstract: Embodiments are directed to implementing rate controls to limit faults detected by timeout and to learning and adjusting an optimal timeout value. In one scenario, a computer system identifies cloud components that have the potential to fail within a time frame that is specified by a timeout value. The computer system establishes a number of components that are allowed to fail during the time frame specified by the timeout value and further determines that the number of component failures within the time frame specified by the timeout value has exceeded the established number of components that are allowed to fail. In response, the computer system increases the timeout value by a specified amount of time to ensure that fewer than or equal to the established number of components fail within the time frame specified by the timeout value.

  • Patent number: 9172551
    Abstract: A form of multicast, referred to as “on-demand multicast,” provides a methodology that allows for “on demand” multicasting of data. On-demand multicast allows clients to join or leave a transmission at any point. There is no transmission session start or end time—the session is continuously available, although data is not necessarily continuously transmitted. Data blocks missed by late-joining clients are retransmitted per amalgamated client requests through multiple transmission cycles until all clients that have joined the transmission session receive all content. Once a client has received all data blocks comprising the content for the session, the client may exit the ongoing session.

  • Patent number: 8996932
    Abstract: Embodiments are directed to establishing a model for testing cloud components and to preventing cascading failures in cloud components. In one scenario, a computer system models identified cloud components (including cloud hardware components and/or cloud software components) as health entities. Each health entity is configured to provide state information about the cloud component. The computer system establishes declarative safety conditions which declaratively describe cloud computing conditions that are to be maintained at the identified cloud components. The computer system then tests against the declarative safety conditions to determine which cloud components are or are becoming problematic. Upon determining that an error has occurred, the computer system notifies users of the error and the component at which the error occurred. Guarded interfaces are established to ensure that actions taken to fix the error do not cause further failures.

  • Patent number: 8924969
    Abstract: A system that includes multiple hosts, each having physical resources, a hypervisor, and a host agent that causes the virtual machines to operate above the hypervisor so as to be abstracted from the physical resources. A host fabric reviews requests to instantiate or upgrade a virtual machine, identifies a corresponding virtual machine image to instantiate the virtual machine from in order to honor the request, and determines whether the virtual machine to be instantiated has a valid lease on the virtual machine image. If the requestor does not have a valid lease, the request is blocked. If the requestor does have a valid lease, the host fabric facilitates the instantiation of the virtual machine from the virtual machine image. This prevents or eliminates the chances of multiple instances of the same virtual machine image writing to the virtual machine image at the same time.
