A technique for efficiently processing resource allocation requests in an on-demand environment. When a user logs into a resource allocation request manager, various resource requirements entered are immediately sent to a remote resource manager to allow for dynamic, real-time feedback to the user who is entering the resource requirements as to any issues or concerns regarding the requested resource(s) or plug-in element(s), such as lack of availability. The user can thus reconfigure or otherwise modify the various resource requests based on this feedback to optimize the overall resource allocation request. This also allows an organization providing services such as computer hosting services to re-allocate resources in advance if a new resource request would exceed a service level agreement outlined in advance with a customer, thereby improving resource planning in a data center environment. In addition, the dynamic feedback on the new resource request that exceeds a service level agreement can be used to develop a new service level agreement or temporary service offer that addresses the unique resource condition.
