Abstract

Systems, methods, and other embodiments associated with automated upgrade of an operating system are described. In one embodiment, a method includes receiving a request for an upgrade package in a gateway server from a remote device and determining a source location for the upgrade package. The example method may also include sending the request to the source location to cause the source location to provide the upgrade package to the remote device.

Claims

1. A non-transitory computer storage medium storing computer-executable instructions that when executed by a gateway server cause the gateway server to perform a method, the instructions comprising instructions configured for:

receiving, by the gateway server over a network, a request for an upgrade package, wherein the request is received from a remote device initiating an operating system (OS) upgrade from a configuration file;

resolving, in the gateway server, a source location for the upgrade package based, at least in part, on metadata in the request, wherein the metadata is from the configuration file,

wherein resolving the source location includes assessing attributes of the remote device to determine whether the remote device is capable of running the OS upgrade;

if the remote device is not capable of running the OS upgrade, returning an error message to the remote device;

if the remote device is capable of running the OS upgrade, redirecting, by the gateway server, the request over the network to the resolved source location for the upgrade package to cause an upgrade server associated with the resolved source location to send the upgrade package to the remote device, wherein the resolved source location is remote from the gateway server and the remote device, and wherein redirecting the request to the resolved source location includes changing a destination of the request from an original destination to the resolved source location; and

further comprising resolving the source location for the upgrade package by;

determining one or more available source locations for the upgrade package by querying a lookup table that includes a plurality of source locations, wherein querying the lookup table includes using attributes of the remote device and the metadata from the request as inputs to the lookup table to determine the one or more available source locations,

wherein the attributes include a proximity of the remote device to the one or more available source locations and performance characteristics of the remote device, and wherein the metadata includes an identifier of the original destination; and

selecting a source location from the one or more available source locations based, at least in part, on one or more attributes of the remote device, wherein selecting the source location includes selecting according to current processing loads of the one or more available source locations and availability of additional upgrade packages.

2. The non-transitory computer storage medium of claim 1, wherein the configuration file is an RPM package manager (RPM) configuration file that identifies at least the upgrade package, wherein the configuration file is obtained individually and separate from the upgrade package, wherein the configuration file is for obtaining the upgrade package and is not associated with another upgrade package, and wherein the operating system is an open source operating system.

3. The non-transitory computer storage medium of claim 1, wherein the gateway server receives the request in response to the remote device initiating a package management system using the configuration file, and wherein the remote device is a client that is installing the upgrade package.

4. The non-transitory computer storage medium of claim 1, wherein the one or more attributes of the remote device include a list of previously installed upgrades on the remote device for the operating system.

5. The non-transitory computer storage medium of claim 1, wherein the gateway server intercepts the request on the network before the request arrives at an original destination identified in the request.

6. The non-transitory computer storage medium of claim 1, wherein the gateway server is a router, and wherein sending the request to the resolved source location includes redirecting the request from an original destination to the resolved source location.

7. An upgrade controller, comprising:

upgrade logic, comprising a hardware processor, configured to;

receive a request for an upgrade package, wherein the request is from a remote device initiating an operating system (OS) upgrade from a configuration file;

resolve a source location for the upgrade package by performing a lookup in a lookup table based, at least in part, on metadata in the request, wherein the metadata is from the configuration file and the source location is in a network associated with the upgrade controller,

wherein the upgrade logic is configured to resolve the source location upon assessing attributes of the remote device to determine whether the remote device is capable of running the upgrade package;

if the remote device is not capable of running the upgrade package, return an error message to the remote device; and

if the remote device is capable of running the upgrade package, redirect the request over a network to the resolved source location for the upgrade package to cause an upgrade server associated with the resolved source location to send the upgrade package to the remote device,

wherein the upgrade controller is in a gateway server that is remote from the resolved source location and the remote device, and wherein the upgrade controller is configured to redirect the request to the resolved source location by changing a destination of the request from an original destination to the resolved source location,

wherein the upgrade logic is further configured to resolve the source location for the upgrade package by;

determining one or more available source locations for the upgrade package from a plurality of source locations in the lookup table based, at least in part, on the metadata and attributes of the remote device,

wherein the attributes include a proximity of the remote device to the one or more available source locations and performance characteristics of the remote device, and wherein the metadata includes an identifier of the original destination, and

selecting a source location from the one or more available source locations based, at least in part, on the attributes of the remote device.

8. The upgrade controller of claim 7, wherein the configuration file is an RPM package manager (RPM) configuration file that identifies at least the upgrade package, wherein the configuration file is obtained individually and separate from the upgrade package, wherein the configuration file is for obtaining the upgrade package and is not associated with another upgrade package, and wherein the operating system is an open source operating system.

9. The upgrade controller of claim 7, wherein the upgrade logic is configured to receive the request in response to the remote device initiating a package management system using the configuration file, and wherein the upgrade logic is configured to receive the request by intercepting the request when the request is being communicated to the original destination.

10. The upgrade controller of claim 7, wherein the one or more attributes of the remote device include a list of previously installed upgrades on the remote device for the operating system.

11. The upgrade controller of claim 7, wherein the upgrade controller is embodied in a gateway server, wherein the upgrade logic is configured to intercept the request on the network before the request arrives at an original destination identified in the request.

12. The upgrade controller of claim 7, wherein the upgrade controller is embodied in a router, and wherein the upgrade logic is configured to send the request to the resolved source location by redirecting the request from an original destination to the resolved source location.

13. A method, comprising:

intercepting, in a gateway server, a request for an upgrade package wherein the request is received over a network from a remote device initiating a configuration file, a request for an upgrade package;

resolving, in the gateway server, a source location for the upgrade package from a lookup table based, at least in part, on metadata in the request,

wherein resolving the source location includes assessing attributes of the remote device to determine whether the remote device is capable of running the OS upgrade;

if the remote device is not capable of running the upgrade package, returning an error message to the remote device; and

if the remote device is capable of running the upgrade package, re-directing, by the gateway server, the request over the network to the source location resolved from the lookup table to cause an upgrade server associated with the source location to send the upgrade package to the remote device, wherein the resolved source location is remote from the gateway server and the remote device and wherein redirecting the request to the source location includes changing a destination of the request from an original destination to the source location,

further comprising resolving the source location for the upgrade package by;

determining one or more available source locations for the upgrade package by querying a lookup table that includes a plurality of source locations for obtaining the upgrade package, wherein querying the lookup table includes using attributes of the remote device and the request as inputs to the lookup table to determine the one or more available source locations,
