responsive to the request, determine availability of the requested computing resources within the distributed computing environment; and allocate a subset of the plurality of computing resources to the application manager for the application based at least in part on a service specification, wherein the subset of the computing resources is less than all of the requested computing resources using relaxed resource requirements received from the application manager based at least in part on an unavailability of the requested computing resources. ### Claim 2 (depends on 1) The system of claim 1, wherein the service specification is received from the application manager and used by the application manager to generate the request. ### Claim 3 (depends on 1) The system of claim 1 wherein the service specification defines a set of constraints for the plurality of computing resources. ### Claim 4 (depends on 3) The system of claim 3, wherein the set of constraints define which computing resources of the plurality of computing resources are allocatable to the application manager to execute the application. ### Claim 5 (depends on 3) The system of claim 3, wherein the request is based at least in part on the set of constraints in relation to constraints for another application of a plurality of applications managed by the application manager. ### Claim 6 (depends on 3) The system of claim 3, wherein the set of constraints defines the requested computing resources to prevent the application from having a single point of failure. ### Claim 7 (depends on 1) The system of claim 1, wherein the service specification defines a priority for one or more of a plurality of applications that includes the application and that is managed by the application manager. ### Claim 8 (depends on 1) The system of claim 1, wherein the instructions are configured to cause the one or more processors to: receive a replacement request for a replacement computing resource from the application manager when there is an instance of failure in the subset of the computing resources on which the application is running; and allocating the replacement computing resource to cause the application manager to restart at least a portion of the application that has failed on the replacement computing resource. ### Claim 9 (depends on 1) The system of claim 1, wherein allocating the subset of the plurality of computing resources comprises: determining that a full set of the requested computing resources are not available, and allocating the subset in response to the determination that the full set of requested computing resources are not available and in response to a subsequent request from the application manager, wherein the service specification defines the relaxed resource requirements when the full set is unavailable. ### Claim 10 (depends on 9) The system of claim 9, wherein the full set of the requested computing resources are not available due to constraints specified in the service specification. ### Claim 11 A method, comprising: receiving a service specification for a first application of a plurality of applications at an application manager implemented using one or more processors, wherein the service specification defines a set of computing resources of a plurality of computing resources of a shared computing environment that are to run each application component of the first application, and wherein the application manager is configured to manage allocations of the plurality of computing resources from a resource supply, manager to the plurality of applications;
