A resource supply manager in communication with the application manager manages a plurality of computing resources in a shared computing environment. The application manager is operable to request the set of required computing resources from the computing resource supply manager, and wherein the resource supply manager determines the availability of the required computing resources within the shared computing environment according to resource allocation policies and allocates computing resources to the application manager, and wherein the application manager is operable manage allocation of the computing resources to the first application, the application manager operable to create and manage deployment of instances of each application component of the first application on the allocated computing resources. ## Claims ### Claim 1 A system to manage a plurality of applications in a distributed computing environment, the system comprising: an application manager executable by one or more processors in a distributed environment, wherein the application manager is configured to: receive a service specification for a first application of the plurality of applications in the distributed computing environment, wherein the service specification defines a first plurality of computing resources used to execute the first application; and request the first plurality of computing resources out of a plurality of potential computing resources that include the first plurality of computing resources; and a resource supply manager executable by one or more processors in the distributed computing environment, wherein the resource supply manager is in communication with the application manager and is configured to: manage the plurality of potential computing resources in the distributed computing environment, receive the request from the application manager; responsive to the request, determine availability of the first plurality of computing resources within the distributed computing environment according to resource allocation policies; and allocate the first plurality of computing resources to the application manager, wherein the application manager is configured to manage allocation of the first plurality of computing resources to the first application. ### Claim 2 (depends on 1) The system of claim 1, wherein the service specification defines a set of constraints for the plurality of potential computing resources, and wherein the application manager takes the constraints into account when requesting the first plurality of computing resources from the resource supply manager. ### Claim 3 (depends on 2) The system of claim 2, wherein the constraints define which computing resources of the plurality of potential computing resources can be allocated to the application manager to execute the first application. ### Claim 4 (depends on 2) The system of claim 2, wherein the request is based at least in part on the set of constraints in relation to constraints for a second application. ### Claim 5 (depends on 4) The system of claim 4, wherein the second application utilizes a second plurality of computing resources to execute the second application. ### Claim 6 (depends on 2) The system of claim 2, wherein the set of constraints define the first plurality of computing resources to prevent the first application from having a single point of fail tire. ### Claim 7 (depends on 1) The system of claim 1, wherein the service specification defines a priority for one or more of the plurality of applications, and wherein the application manager manages the plurality of applications based at least in part on the priority. ### Claim 8 (depends on 1) The system of claim 1, wherein the application manager monitors a status of the first plurality of computing resources on which the first application is running, and where there is an instance of failure, the application manager restarts a portion of the first application on corresponding allocated computing resource of the first plurality of computing resources. ### Claim 9 (depends on 1) The system of claim 1, wherein the application manager monitors a status of the first plurality of computing resources on which the first application is running, and where there is an instance of failure, the application manager requests a replacement computing resource from the resource supply manager and restarts a portion of the first application that has failed on the corresponding replacement computing resource. ### Claim 10 A method, comprising: managing, via an application manager, a plurality of applications in a distributed computing environment; receiving, at the application manager, a service specification for a first application of the plurality of applications, wherein the service specification defines a plurality of computing resources used to execute the first application;
