Phased server reservation with a server level allocation and an allotment level allocation
A method of resource allocation is disclosed. A request from a user to allocate computing resources for specified compute processing is received. A server level allocation is performed, including by determining a full server reservation estimate corresponding to the request, wherein the full server reservation estimate comprises a count of how many servers are reserved for the specified compute processing. A virtual server pool is formed based at least in part on the full server reservation estimate. An allotment level allocation is performed, including by assigning among the virtual server pool one or more allotments for the specified compute processing.

9 . The method of claim 1 , wherein the tax percentage rate has a range between five percent and ten percent.
10 . The method of claim 1 , wherein the forming of the virtual server pool based at least in part on the full server reservation estimate comprises:
combining the full server reservation estimate corresponding to the request with one or more other full server reservation estimates corresponding to one or more other requests to allocate the computing resources for the specified compute processing to determine a number of servers forming the virtual server pool.
11 . The method of claim 1 , wherein the forming of the virtual server pool based at least in part on the full server reservation estimate comprises:
combining the full server reservation estimate corresponding to the request, one or more other full server reservation estimates corresponding to one or more other requests to allocate the computing resources for the specified compute processing, and a predetermined number of buffer servers to determine a number of servers forming the virtual server pool.
12 . The method of claim 1 , further comprising:
configuring a solver performing an allotment level allocation such that a previous allotment to the user is assigned to the user.
13 . A system, comprising:
one or more processors configured to:
receive a request from a user to allocate computing resources for specified compute processing;
determine a full server reservation estimate corresponding to the request, wherein the full server reservation estimate comprises a count of how many servers are reserved for the specified compute processing, and wherein the full server reservation estimate is based at least in part on a scale factor that is greater than one, and wherein the scale factor is based on a tax percentage rate;
form a virtual server pool based at least in part on the full server reservation estimate;
assigning among the virtual server pool one or more allotments for the specified compute processing, wherein the one or more allotments is a are separate less than full server portions of one or more servers in the virtual server pool, wherein the request from the user to allocate the computing resources for the specified compute processing specifies a memory shape size and a memory shape count associated with the one or more allotments for the specified compute processing; and
allocate the one or more allotments for the request; and
memory coupled to at least one of the one or more processors and configured to provide the at least one of the one or more processors with instructions.
14 . The system of claim 13 , wherein the request from the user to allocate the computing resources for the specified compute processing specifies that an allotment of the one or more allotments for the specified compute processing has a granularity of a portion of a full server.
15 . The system of claim 13 , wherein the memory shape count specifies a number of requested units of memory with the memory shape size.
16 . The system of claim 13 , wherein being configured to form the virtual server pool based at least in part on the full server reservation estimate comprises being configured to:
combine the full server reservation estimate corresponding to the request with one or more other full server reservation estimates corresponding to one or more other requests to allocate the computing resources for the specified compute processing to determine a number of servers forming the virtual server pool.
17 . A computer program product embodied in a non-transitory computer readable medium and comprising computer instructions for:
receiving a request from a user to allocate computing resources for specified compute processing;
