Abstract

A system and method for patching cloud services for use with a cloud computing environment. In accordance with an embodiment, a cloud environment includes a cloud services infrastructure, which allows a suite of software applications, middleware, and database offerings to be delivered to customers in a self-service, elastically scalable manner. Over time, it may become necessary to update one or more of the deployed services. In accordance with an embodiment, services can be patched using a two phase approach. During an offline phase, patches are used to update shared components, such as middleware volumes, without disrupting any currently running services. Subsequently, during an online phase, patched components are enabled on all service hosts, and any necessary domain update/upgrade operations are invoked.

First claim

What is claimed is:

1. A system for patching cloud services for use with a cloud computing environment, comprising:
one or more computers, including a cloud computing environment executing thereon;
wherein the cloud computing environment provides hardware resources to a plurality of tenants substantially isolated from one another;
a cloud service component, which orchestrates, alone or in combination with other cloud computing environment components, creation and updating of one or more instances of a cloud service, including provisioning and deployment of the one or more instances of the cloud service customized for use by a tenant from the plurality of tenants and/or deployment of user applications thereto; and
a patching component that receives patch or update information for one or more patches to the cloud service based on a version of the cloud service, and applies the one or more patches to each of the one or more instances of the cloud service that is deployed for use by the tenant from the plurality of tenants and shared software components therein using a two-phase approach;
wherein, during a first phase of the two-phase approach, the one or more patches for the shared software components are configured and deployed to a shared volume visible to each of the one or more deployed instances of the cloud service; and
wherein, during a second phase of the two-phase approach occurring within a maintenance window of system down time defined for the one or more deployed instances of the cloud service, the configured one or more patches for the shared software components are applied to the shared software components within each of the one or more deployed instances of the cloud service and thereafter, each of the one or more deployed instances of the cloud service is restarted.

2. The system of claim 1 , wherein the shared volume contains all tooling components and is mounted on all service hosts.

3. The system of claim 1 , wherein one or more of the one or more patches are composite patches that patch a plurality of different software components within at least one of the one or more deployed instances of the cloud service.

4. The system of claim 1 , wherein one or more of the one or more deployed instances of the cloud service are Java cloud service instances, and wherein one or more of the one or more patches are composite patches that patch a plurality of different software components within the Java cloud service instances running within the cloud computing environment.

5. The system of claim 1 , wherein the shared software components within each of the one or more deployed instances of the cloud service include one or more of an operating system component, application server component, application, or other component.

6. The system of claim 1 , further comprising:
a patch inventory for storing metadata of the one or more applied patches, wherein the patching component uses the patch inventory to keep track of what patches have been applied to each of the one or more deployed instances of the cloud service and the shared software components therein.

7. The system of claim 1 , wherein configuring the one or more patches for the shared software components during the first phase of the two-phase approach includes setting values of middleware volumes and locations thereof.

8. A method of patching cloud services for use with a cloud computing environment, comprising:
providing at one or more computers, a cloud computing environment executing thereon;
wherein the cloud computing environment provides hardware resources to a plurality of tenants substantially isolated from one another;
providing a cloud service component, which orchestrates, alone or in combination with other cloud computing environment components, creation and updating of one or more instances of a cloud service, including provisioning and deployment of the one or more instances of the cloud service customized for use by a tenant from the plurality of tenants and/or deployment of user applications thereto; and
receiving patch or update information for one or more patches to the cloud service based on a version of the cloud service, and applying the one or more patches to each of the one or more instances of the cloud service that is deployed for use by the tenant from the plurality of tenants and shared software components therein using a two-phase approach;
wherein, during a first phase of the two-phase approach, the one or more patches for the shared software components are configured and deployed to a shared volume visible to each of the one or more deployed instances of the cloud service; and
wherein, during a second phase of the two-phase approach occurring within a maintenance window of system down time defined for the one or more deployed instances of the cloud service, the configured one or more patches for the shared software components are applied to the shared software components within each of the one or more deployed instances of the cloud service and thereafter, each of the one or more deployed instances of the cloud service is restarted.

9. The method of claim 8 , wherein the shared volume contains all tooling components and is mounted on all service hosts.

10. The method of claim 8 , wherein one or more of the one or more patches are composite patches that patch a plurality of different software components within at least one of the one or more deployed instances of the cloud service.

11. The method of claim 8 , wherein one or more of the one or more deployed instances of the cloud service are Java cloud service instances, and wherein one or more of the one or more patches are composite patches that patch a plurality of different software components within the Java cloud service instances running within the cloud computing environment.

12. The method of claim 8 , wherein the shared software components within each of the one or more deployed instances of the cloud service include one or more of an operating system component, application server component, application, or other component.

13. The method of claim 8 , further comprising:
maintaining a patch inventory that stores metadata of the one or more applied patches, wherein a patching component uses the patch inventory to keep track of what patches have been applied to each of the one or more deployed instances of the cloud service and the shared software components therein.

14. The method of claim 8 , wherein configuring the one or more patches for the shared software components during the first phase of the two-phase approach includes setting values of middleware volumes and locations thereof.

15. A non-transitory computer readable storage medium, including instructions stored thereon which when read and executed by one or more computers cause the one or more computers to perform the steps comprising:
providing at one or more computers, a cloud computing environment executing thereon;
wherein the cloud computing environment provides hardware resources to a plurality of tenants substantially isolated from one another;
providing a cloud service component, which orchestrates, alone or in combination with other cloud computing environment components, creation and updating of one or more instances of a cloud service, including provisioning and deployment of the one or more instances of the cloud service customized for use by a tenant from the plurality of tenants and/or deployment of user applications thereto; and
receiving patch or update information for one or more patches to the cloud service based on a version of the cloud service, and applying the one or more patches to each
