Method and system for modeling and analyzing computing resource requirements of software applications in a shared and distributed computing environment

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;
• requesting, by the application manager, the set of computing resources from the resource supply manager;
• receiving, at the application manager from the resource supply manager, an indication of allocated computing resources of the plurality of computing resources allocated to the first application, wherein the allocated computing resources include fewer resources than are included in the set of computing resources based at least in part on respective availability statuses of the set of computing resources determined by the resource supply manager using resource allocation policies and the service specification indicating an allowable reduction in allocated resources from the set of computing resources to the allocated computing resources;
• and
• deploying and managing instances of each application component of the first application on the allocated computing resources using the application manager.

A tangible;

• non-transitory, and computer-readable medium storing instructions, that when executed by one or more processors are configured to cause the one or more processors to:
• receive, at an application manager, a service specification for an application of a plurality of applications that defines a set of computing resources that are to run each application component of the application, wherein the application manager is implemented using one or more processors and is configured to manage the plurality of applications each having one or more application components in a shared computing environment;
• transmit a request, from the application manager to a resource supply manager, for the set of computing resources from the resource supply manager;
• receive, at the application manager and from the resource supply manager, an indication that the set of computing resources is unavailable based on resource allocation policies;
• in response to receiving the indication, transmit a subsequent request, from the application manager to the resource supply manager, for a relaxed set of computing resources that comprises only a portion of the set of the computing resources;
• receive;
• at the application manager from the resource supply manager;
• an allocation of the portion of the set of computing resources to the application;
• and
• deploy and manage instances of each application component of the application on the portion of the set of computing resources.
