The techniques include generating an application template and an application template clone that include application attributes usable to deploy an application stack at an application site. The techniques also include sending the application template clone to a disaster recovery site group to await deployment instructions. In some examples, an observer may determine that a health metric of the application site indicates that a disaster recovery process be triggered. A disaster recovery site of the disaster recovery site group may be selected based at least in part on a performance metric. The application stack may be deployed at the disaster recovery site utilizing the application template clone. ## Claims ### Claim 1 A computer-implemented method comprising: sending an application template to an application site group, the application template representing application attributes that are usable to deploy an application stack at an application site of the application site group; causing the application stack to be deployed at the application site; generating an application template clone of the application template; sending the application template clone to one or more disaster recovery sites; in response to a predicted failure of the application stack at the application site, selecting, based at least in part on a performance metric associated with the one or more disaster recovery sites, a particular disaster recovery site for deployment of the application stack; and causing the particular disaster recovery site to deploy the application stack using the application template clone. ### Claim 2 (depends on 1) The computer-implemented method of claim 1, wherein the application template and the application template clone comprise application structure information and application data that are used to deploy the application stack. ### Claim 3 (depends on 1) The computer-implemented method of claim 1, wherein the predicted failure of the application stack is based at least in part on monitoring a health metric that comprises a resource utilization value. ### Claim 4 (depends on 1) The computer-implemented method of claim 1, further comprising: storing the application template clone in memory at the particular disaster recovery site; and provisioning the application template clone to deploy the application stack at the particular disaster recovery site in response to the predicted failure of the application stack at the application site. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, wherein the performance metric comprises a resource utilization pattern. ### Claim 6 (depends on 5) The computer-implemented method of claim 5, further comprising: ranking the one or more disaster recovery sites based at least in part on the resource utilization pattern;
