Abstract

Technologies are described for updating a live system with static changes. According to some examples, changes such as installing and/or removing features may be applied to a cloud based service in live environment without disrupting the service. New software may be patched and installed on an upgraded machine (i.e., server). New features, diagnostics, and language packs may be added. Existing features and certificates may be removed. To accomplish these, new software to be installed and existing software to be removed may be detected. Removal and additions may be performed without preparation and activation of replacement farms.

First claim

What is claimed is:

1. A computing device to provide updates to a live system with static changes, the computing device comprising:
a memory;
a processor coupled to the memory, the processor executing a cloud based service in conjunction with instructions stored in the memory, wherein the cloud based service includes:
an orchestration module to manage updates to the cloud based service, the orchestration module configured to:
confirm server level upgradability by verifying that one or more properties indicate that a server farm hosting the cloud based service is capable of an upgrade and the server farm is backward compatible;
upgrade a configuration database associated with the cloud based service by setting a status of configuration database objects to indicate the upgrade being in progress in order to notify other components of the service such that no write operation is allowed on the configuration database until the upgrade is completed;
construct an object tree that represents an upgrade hierarchy, the object tree comprising a plurality of objects configurable to be marked with an upgrade status, wherein the plurality of objects include one or more of: a server object representing a server in the server farm, a webservice instance object representing an instance of the cloud based service, a webservice object representing the cloud based service, a web application object representing an application within the cloud based service, or a website object representing a website associated with the cloud based service;
determine an object to be upgraded with the object tree, removed from the object tree, or added to the object tree based on the upgrade hierarchy; and
upgrade, remove, or add a component of the cloud based service represented by the object according to the determination.

2. The computing device of claim 1 , wherein the orchestration module is further configured to:
scan through servers within the cloud based service to ensure each server is upgraded.

3. The computing device of claim 1 , wherein each server object is assigned a status property.

4. The computing device of claim 3 , wherein the status property includes one of a plurality of values indicating that the server represented by the server object is running, enabled, disabled, offline, being unprovisioned, being provisioned, or being patched.

5. The computing device of claim 1 , wherein the orchestration module is configured to upgrade the configuration database by:
performing a schema upgrade phase, wherein configuration database schemas are upgraded for tables and views,
performing a stored procedure upgrade phase, wherein stored procedures are upgraded, and
performing a data upgrade phase, wherein data in the configuration database is upgraded.

6. The computing device of claim 1 , wherein the computing device is a management server of a datacenter executing the cloud based service.

7. The computing device of claim 1 , wherein the computing device is a third party upgrade server communicatively coupled to a datacenter executing the cloud based service.

8. A method executed at a datacenter server to provide updates to a live system with static changes, the method comprising:
confirming server level upgradability by verifying that one or more properties indicate that a server farm hosting a service is capable of an upgrade and the server farm is backward compatible;
upgrading a configuration database associated with the service by setting a status of configuration database objects to indicate the upgrade being in progress in order to notify other components of the service such that no write operation is allowed on the configuration database until the upgrade is completed;
constructing an object tree that represents an upgrade hierarchy, the object tree comprising a plurality of objects configurable to be marked with an upgrade status, wherein the plurality of objects includes one or more of: a server object representing a server in the server farm, a webservice instance object representing an instance of a cloud based service, a webservice object representing the cloud based service, a web application object representing an application within the cloud based service, or a website object representing a website associated with the cloud based service;
determine an object to be upgraded with the object tree, removed from the object tree, or added to the object tree based on the upgrade hierarchy; and
upgrading, removing, or adding a component of the cloud based service represented by the object according to the determination.

9. The method of claim 8 , further comprising:
increasing a granularity of objects at a server level.

10. The method of claim 8 , wherein determining the object to be upgraded with the object tree, removed from the object tree, or added to the object tree comprises:
checking a status of each object;
determining whether each object is upgradable;
determining whether each object needs an upgrade; and
determining whether each object is backward compatible.

11. A computer-readable memory device with instructions stored thereon to provide updates to a cloud based collaboration service with static changes, the instructions comprising:
confirming server level upgradability by verifying that one or more properties indicate that a server farm hosting the cloud based collaboration service is capable of an upgrade and the server farm is backward compatible;
upgrading a configuration database associated with the cloud based collaboration service by setting a status of configuration database objects to indicate the upgrade being in progress in order to notify other components of the cloud based collaboration service such that no write operation is allowed on the configuration database until the upgrade is completed;
constructing an object tree that represents an upgrade hierarchy, the object tree comprising a plurality of objects configurable to be marked with an upgrade status, wherein the plurality of objects includes one or more of: a server level object representing a server in the server farm, a webservice instance object representing an instance of the cloud based collaboration service, a webservice object representing the cloud based collaboration service, a web application object representing an application within the cloud based collaboration service, or a website object representing a website associated with the cloud based collaboration service;
determining an object to be upgraded with the object tree, removed from the object tree, or added to the object tree based on the object tree;
upgrading, removing, or adding a component of the cloud based collaboration service represented by the object according to the determination; and
scanning through virtual machines (VMs) within the cloud based collaboration service to ensure each VM is upgraded.

12. The computer-readable memory device of claim 11 , wherein the instructions further comprise:
employing a GridVM object and a GridFarm object to manage upgrade of the VMs.

13. The computer-readable memory device of claim 12 , wherein a property on the GridVM object and the GridFarm object is used to indicate up to which action the upgrade is run into.

14. The computer-readable memory device of claim 13 , wherein the instructions further comprise:
using the property on the GridVM object and the GridFarm object to determine which action to start a subsequent upgrade from.
