INCREASING AVAILABILITY OF STATEFUL APPLICATIONS
First Claim
1. One or more computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method for facilitating interaction between a fabric controller of a cloud-computing network and a service application running in the cloud-computing network, the method comprising:
- selecting a first update domain (UD) that includes one or more role instances of the service application, wherein the one or more role instances are operating in an online condition;
preparing the first UD for execution of a tenant job, wherein preparing the first UD comprises;
(a) notifying a management role within the service application of the fabric controller'"'"'s intent to execute the tenant job; and
(b) receiving a response from the management role upon determining whether an internal state of the one or more role instances affected by the tenant job is replicated on a portion of the service application that is unaffected by the tenant job;
initiating disablement of the one or more role instances of the first UD to an offline condition; and
allowing the tenant job to execute on the first UD.

Abstract
Methods, systems, and computer-readable media for facilitating coordination between a fabric controller of a cloud-computing network and a service application running in the cloud-computing network are provided. Initially, an update domain (UD) that includes role instance(s) of the service application is selected, where the service application represents a stateful application is targeted for receiving a tenant job executed thereon. The process of coordination involves preparing the UD for execution of the tenant job, disabling the role instance(s) of the UD to an offline condition, allowing the tenant job to execute, and restoring the role instance(s) to an online condition upon completing execution of the tenant job. Preparing the UD includes notifying a management role established within the service application of the fabric controller'"'"'s intent to execute the tenant job and receiving a management-role response communicating a presence of replications of internal state(s) of the role instance(s) affected by the tenant job.

10. A computerized method for scheduling a high-priority job when executing a tenant job, the method comprising:
-
receiving an indication to execute the tenant job on a service application; identifying an update domain (UD) that includes one or more role instances of the service application, wherein the one or more role instances are operating in an online condition; preparing the UD for execution of the tenant job; initiating disablement of the one or more role instances of the UD to an offline condition; receiving an indication to implement a high-priority job, wherein the high-priority job is predetermined to preempt the tenant job within a priority scheme; yielding deployment of the tenant job to the high-priority job, wherein the process of yielding comprises; (a) instructing the service application to perform a truncated set of operations that restore the one or more role instances to the online condition; (b) placing the tenant job on hold; and (c) initiating execution of the high-priority job on the one or more role instances; upon completing execution of the high-priority job, resuming deployment of the tenant job, wherein the process of resuming comprises; (a) reinitiating disablement of the one or more role instances of the UD to the offline condition; and (b) allowing execution of the tenant job on the one or more role instances; and upon completing execution of the tenant job, restoring the one or more role instances of the UD to the online condition. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A computer system for performing a method that coordinates the incremental deployment of a tenant job to portions of a service application, the computer system comprising a processing unit coupled to a computer storage medium, the computer storage medium having stored thereon a plurality of computer software components executable by the processing unit, the computer software components comprising:
-
one or more role instances of the service application, wherein the role instances represent the component programs that support the functionality of the service application; a tenant-change manager for directing deployment of the tenant job, wherein the process of directing deployment involves communicating an indication of the deployment of the tenant job, initiating disablement of the one or more role instances to an offline condition, allowing for execution of the tenant job on the one or more role instances, and initiating restoration of the one or more role instances to the online condition; and a management role of the service application for monitoring an internal state of the one or more role instances, wherein, upon receiving the indication of the deployment of the tenant job, the management role is responsible for determining whether the monitored internal state of the one or more role instances affected by the tenant job is replicated on a portion of the service application that is unaffected by the tenant job and for communicating an indication of availability of the internal state to the tenant-change manager. - View Dependent Claims (18, 19, 20)
