Abstract

Systems and methods are disclosed that facilitate the updating of target host computing devices based on versioning information. A set of computing devices are provisioned with a local computing device management component. Each local computing device management component periodically transmits a request to a version control component to determine whether version information associated with the respective computing device corresponds to version filter information. Based on a processing of the version filter information with the current version information of the computing device, the version control component can facilitate the implementation of updates to the requesting computing device. Moreover, clients may be enabled to cause a local computing device management component to transmit a request to the version control component, thereby enabling real-time or near-real-updates to computing devices.

Claims21

Dependent claims

A computer-implemented method for managing a host computing device, wherein the host computing device hosts one or more virtual machine instances, the method comprising:

under control of one or more processors configured with specific executable instructions,
obtaining, at a version control component, desired version information for a set of host computing devices, wherein the desired version information corresponds to a desired configuration of each of the set of host computing devices;
during each interval in a set of intervals:
receiving a version verification request at the version control component from a host computing device of the set of host computing devices, wherein the version verification request includes version information associated with a current configuration of the host computing device, and wherein the version verification request is received in accordance with a time distribution of version verification requests across the set of computing devices;
determining, at the version control component, whether the version information included in the request corresponds to the desired version information for the host computing device;
transmitting information responsive to the determination to the host computing device from the version control component;
receiving, at the version control component, a version verification trigger request from a client computing device, wherein the version verification trigger request corresponds to a request to initiate a version verification on the host computing device responsive to a modification of the desired version information of the host computing device;
in response to a modification of the desired version information of the host computing device, transmitting a version trigger command from the version control component to the host computing device to cause the host computing device to transmit a version verification request, wherein the version trigger command does not include the desired version information;
receiving, at the version control component, a second version verification request from the host computing device;
and
transmitting second information responsive to the host computing device from the version control component.

8 more elements

A system for managing computing devices, the system comprising:

at least one data store configured to store desired version information for a target computing device, wherein the desired version information corresponds to a desired configuration of the target computing device, and wherein the target computing device corresponds to a host computing device hosting one or more virtual machine instances;
and
one or more processors in communication with the at least one data store, the one or more processors configured to:
receive a request to trigger a version verification on the target computing device;
transmit a version trigger to the target computing device to cause the target computing device to transmit a version verification request, wherein the version trigger corresponds to a trigger file, wherein the target computing device is configured to periodically monitor for the existence of the trigger file and transmit a version verification request in response to detecting the trigger file, and wherein the version trigger identifies a timing, based on a time distribution of configuration requests, for transmitting a version verification request;
receive a version verification request in accordance with the time distribution, responsive to received version trigger information, to check for a configuration update for the target computing device, the version verification request including version information associated with a current configuration of the target computing device;
determine whether the version information included in the request corresponds to the desired version information in the at least one data store;
and
transmit information responsive to the determination to the target computing device.

6 more elements

A computer-implemented method for managing computing devices, the method comprising:

under control of one or more processors configured with specific executable instructions,
receiving a request to trigger a version verification on a target computing device that hosts one or more virtual machine instances;
transmitting a trigger file to the target computing device to cause the target computing device to transmit a version verification request, wherein the target computing device is configured to transmit a version verification request in response to detecting the trigger file, and wherein the trigger file identifies a timing, based on a time distribution of configuration requests, for transmitting a version verification request;
receiving a version verification request responsive to received version trigger information in accordance with the time distribution, to check for a configuration update for the target computing device, the version verification request including version information associated with a current configuration of the target computing device;
determining whether the version information included in the request corresponds to a desired configuration of the target computing device;
and
transmitting information responsive to the determination to the requesting target computing device.
