VMs are booted in a big data framework within the context of a cluster of computing and storage devices. The big data framework comprises a distributed, location aware file system and a cluster resource manager that assigns computing resources. VM images are stored as data in the distributed file system. Computing resources and hosts are allocated to specific VMs. The allocated hosts are within given levels of proximity to target data. VMs are booted and run on the hosts, and applications are run on the VMs, processing target data in the distributed file system. Prior to booting a given VM, a stored image can be converted between formats. This enables dynamically determining the VM format at boot time, based on what is supported by the hypervisor available on the target host.

Booting virtual machine instances in a distributed data processing architecture

A computer-implemented method for provisioning computing systems with applications may include (1) identifying a request to provision a computing system with an application in a pre-determined configuration state, where the pre-determined configuration state of the application is separated from a prior configuration state of the application by at least one configuration step, (2) locating a backup system that stores a pre-configured instance of the application that has been configured to the pre-determined configuration state at least in part by the configuration step, (3) retrieving the pre-configured instance of the application from the backup system, and (4) provisioning the computing system with the application in the pre-determined configuration state without performing the configuration step by copying the pre-configured instance of application that was retrieved from the backup system to the computing system. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for provisioning computing systems with applications

Various systems and methods for automated error recovery in workflows. For example, one method involves executing operations of a first task. A workflow includes multiple tasks that include the first task. Each of the tasks represents one or more operations that are configured to access one or more elements. The method also involves detecting an error in execution of the one or more first operations, where the error indicates inaccessible elements. In response to the error detection, the method can automatically execute an error recovery portion of the first task. Execution of the error recovery portion includes receiving one or more responses, where the first task can use the response(s) instead of the one or more inaccessible elements.

Automated error recovery for workflows

A method for maintaining applications may include: (1) receiving a request to recover a first application, (2) identifying a first production topology of the first application that identifies a set of resources upon which the application depends, (3) maintaining a template for transforming the first production topology of the first application into a first recovery topology for the first application, the template comprising information for mapping the first production topology to the first recovery topology, (4) applying the template to the first production topology at a first point in time to create the first recovery topology, and (5) recovering the first application to a first computing system using the first recovery topology. Various other methods, systems, and computer-readable media are also disclosed herein.

Systems and methods for managing applications

Techniques are disclosed relating to storing a log of write operations made to a first storage device by one of a plurality of host computers running an instance of a distributed application. The log of write operations is stored at a second storage device. The plurality of host computers communicate status information to the second storage device over respective communication paths. Upon a failure to communicate status information between one of the host computers and the second storage device, the second storage device reads from a predetermined location in the first storage device to determine whether the host computer is still performing write operations. If the second storage device reads an expected signature value written by the host computer, the host computer is deemed to have written data, which indicates that the host computer is operational but that the write operations have not been recorded by the second storage device.
