In one embodiment, an exemplary method comprises receiving a request to assign a first role to at least one virtual server; configuring the virtual server to associate the first role with a first resource of the virtual server; modifying a database to include an identifier associated with the virtual server and an identifier of the first role assigned to the virtual server; receiving, from the virtual server, indications of resource usage for a plurality of roles; calculating an efficiency metric associated with the first role, the efficiency based on resource usage associated with the first role and resource usage associated with the plurality of roles; modifying a user interface element for presentation on a web page to include the calculated efficiency metric for the first role; receiving a request from a user; and delivering the web page. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 A first server having at least one designated role, the server comprising: a memory storing instructions; and at least one processor configured to execute the instructions to: receive a resource usage request for at least one resource from a first client; determine a role associated with the resource usage request; determine if an efficiency metric of the server satisfies a threshold; allocate, based on the resource usage request and when the efficiency metric satisfies the threshold, an amount of the at least one resource; generate an indication of resource usage, the indication including the determined role; and provide the indication to a system, wherein the server is configured to automatically transfer the at least one designated role to a second server when the efficiency metric does not satisfy the threshold. ### Claim 22 (depends on 21) The first server of claim 21, wherein the resource usage request comprises a request for an operation, a request to modify data, a request to store data, or a request to transfer data. ### Claim 23 (depends on 21) The first server of claim 21, wherein the role associated with the resource usage request is determined based on an identity of the first client. ### Claim 24 (depends on 23) The first server of claim 23, wherein the identity of the first client comprises a media access control (MAC) address or an Internet Protocol (IP) address. ### Claim 25 (depends on 21) The first server of claim 21, wherein: the resource usage request is a first resource usage request; and the role associated with the resource usage request is determined based on a similarity of the first received resource usage request and a second resource usage request. ### Claim 26 (depends on 21) The first server of claim 21, wherein the at least one resource is a processing resource, a storage resource, or a connectivity resource. ### Claim 27 (depends on 21) The first server of claim 21, wherein automatically transferring the at least one designated role to the second server comprises: assembling a configuration file containing settings or variables; and transferring the configuration file to the second server. ### Claim 28 (depends on 21) The first server of claim 21, wherein the indication is provided to the system in response to a request received via an application programming interface (API). ### Claim 29 (depends on 21) The first server of claim 21, wherein the at least one processor is further configured to execute an instruction to determine the efficiency metric. ### Claim 30 (depends on 29) The first server of claim 29, wherein determining the efficiency metric comprises: receiving a plurality of indications of resource usages;

determining a second difference between the resource usage associated with a highest resource usage among the plurality and the resource usage associated with the lowest resource usage among the plurality; and dividing the first difference by the second difference to determine the efficiency metric. ### Claim 33 (depends on 30) The first server of claim 30, wherein determining the efficiency metric further comprises: determining a first difference between a natural logarithm of the resource usage associated with the determined role and a natural logarithm of a lowest resource usage among the plurality; determining a second difference between a natural logarithm of the resource usage associated with a highest resource usage among the plurality and the natural logarithm of the resource usage associated with the lowest resource usage among the plurality; and dividing the first difference by the second difference to determine the efficiency metric. ### Claim 34 (depends on 29) The first server of claim 29, wherein the efficiency metric is determined based on usage statistics aggregated over a period of time. ### Claim 35 (depends on 21) The first server of claim 21, wherein the first server and the second server are virtual servers. ### Claim 36 A computer-implemented method for transferring roles between servers, the method comprising receiving a resource usage request for at least one resource from a first client; determining a role associated with the resource usage request; determining if an efficiency metric of the server satisfies a threshold; allocating, based on the resource usage request and when the efficiency metric satisfies the threshold, an amount of the at least one resource; generating an indication of resource usage, the indication including the determined role; providing the indication to a system; and automatically transferring at least one designated role from a first server to a second server when the efficiency metric does not satisfy the threshold. ### Claim 37 (depends on 36) The computer-implemented method of claim 36, wherein the role is determined based on an identity of the first client. ### Claim 38 (depends on 36) The computer-implemented method of claim 36 further comprising: assembling a configuration file containing settings or variables;
