Abstract

A cloud manager controls the deployment and management of machines for an online service. A build system creates deployment-ready virtual hard disks (VHDs) that are installed on machines that are spread across one or more networks in farms that each may include different configurations. The build system is configured to build VHDs of differing configurations that depend on a role of the virtual machine (VM) for which the VHD will be used. The build system uses the VHDs to create virtual machines (VMs) in both test and production environments for the online service. The cloud manager system automatically provisions machines with the created virtual hard disks (VHDs). Identical VHDs can be installed directly on the machines that have already been tested.

Claims

1. A system for managing a server farm, comprising:

a data store configured to store a farm goal, wherein the farm goal is maintained within the data store;

a build system that is operative to;

access one or more build projects that specify actions to create a set of virtual hard disks and virtual machines for deployment; and

configure the farm goal responsive to changes in capacity needs of the server farm; and

a manager that is operative to;

access a goal that specifies at least a target number of machines for a virtual machine role by retrieving the farm goal from the data store; and

automatically deploy virtual machines built using the virtual hard disks based on the farm goal.

2. The system of claim 1, wherein the data store is further configured to store virtual hard disks that are used in deployment of machines.

3. The system of claim 1, wherein the farm goal is a first farm goal of a plurality of farm goals maintained by the data store for a plurality of different server farms;

and wherein the manager is further operative to;

access a second farm goal by retrieving the second farm goal from the data store, wherein the second farm goal specifies at least a target number of machines for a virtual machine role for a second server farm different from a server farm associated with the first goal; and

automatically deploy, at the second server farm, virtual machines built using the virtual hard disks based on the second farm goal.

4. The system of claim 1, wherein the farm goal includes a plurality of target numbers for a plurality of virtual machine roles.

5. The system of claim 1, wherein the build system is further operative to decommission virtual machines based on the farm goal.

6. The system of claim 1, wherein configuring the farm goal is further responsive to changes in activity of the server farm.

7. The system of claim 1, wherein the virtual machine role specifies a virtual hard disk, a number of processors used by the virtual machine, and an amount of memory used by the virtual machine.

8. A method for deploying virtual machines in a server farm, the method comprising:

accessing one or more build projects that specify actions to perform to create a set of virtual hard disks and virtual machines for deployment;

accessing a farm goal that specifies a target number of machines for a virtual machine role, wherein accessing the farm goal comprises retrieving the farm goal from a data store that maintains the farm goal;

configuring the farm goal responsive to changes in capacity needs of the server farm; and

automatically deploying virtual machines built using the virtual hard disks based on the farm goal.

9. The method of claim 8, further comprising:

storing the set of virtual hard disks in a data store; and

accessing a virtual hard disk from the set of virtual hard disks stored in the data store to build a virtual machine.

10. The method of claim 8, wherein the data store comprises a database storing the farm goal.

11. The method of claim 8, wherein the farm goal includes a plurality of target numbers for a plurality of virtual machine roles.

12. The method of claim 8, further comprising decommissioning a virtual machine based on the farm goal.

13. The method of claim 8, wherein configuring the farm goal is further responsive to changes in activity of the server farm.

14. The method of claim 8, wherein the virtual machine role specifies a virtual hard disk, a number of processors used by the virtual machine, and an amount of memory used by the virtual machine.

15. A system for managing a server farm, comprising:

a data store configured to store data for the server farm and maintain a farm goal;

a build machine that is operative to;

access one or more build projects that specify actions to perform to create a set of virtual hard disks; and

store the set of virtual hard disks in the data store; and

a manager comprising;

at least one processing device; and

at least one computer readable data storage device storing instructions that, when executed by the at least one processing device, cause the build machine to;

access the farm goal in the data store that specifies a plurality of target numbers for a plurality of virtual machine roles;

configure the farm goal responsive to changes in capacity needs of the server farm;

build a set of virtual machines using the virtual hard disks; and

automatically deploy virtual machines built using the virtual hard disks based on the farm goal.

16. The system of claim 15, wherein the virtual machine role specifies a virtual hard disk, a number of processors used by the virtual machine, and an amount of memory used by the virtual machine.

17. The system of claim 15, wherein the at least one computer readable data storage device storing instructions that, when executed by the at least one processing device, further cause the manager to decommission virtual machines based on the farm goal.

18. The system of claim 15, wherein the at least one computer readable data storage device storing instructions that, when executed by the at least one processing device, further cause the manager to automatically configure the farm goal further responsive to changes in activity of the server farm.
