Request routing in a networked environment

A system for request routing comprising:

• a processor operative to execute instructions stored in memory to obtain registration information at a service provider for registering a content provider with the service provider, the registration information including a registration request by the content provider for the service provider to provide at least a portion of request routing functionality associated with one or more resources provided by the content provider, wherein the registration request for request routing functionality is different from a registration request for hosting or providing content on behalf of the content provider;
• a first network point of presence associated with a service provider, wherein the first network point of presence includes a DNS server that receives a DNS query from a client computing device, wherein the DNS query corresponds to a requested resource associated with a first resource identifier, and wherein the DNS server in the first network point of presence includes a processor and is operative to execute instructions stored in memory to:
• provide the client computing device with at least one of an identifier corresponding to a storage component for the requested resource based on supplemental request routing information not included in the first resource identifier or an alternative resource identifier query to resolve to a domain corresponding to the service provider, wherein the alternative resource identifier includes the supplemental request routing information not included in the first resource identifier.

A non-transitory, computer-readable storage medium having computer-executable modules for managing resources, the computer-executable modules comprising:

• one or more modules configured to:
• obtain registration information at a service provider for registering a content provider with the service provider, the registration information including a registration request by the content provider for the service provider to provide at least a portion of request routing functionality associated with one or more resources provided by the content provider, wherein the registration request for request routing functionality is different from a registration request for hosting or providing content on behalf of the content provider;
• obtain a DNS query from a client computing device at a first DNS server, wherein the DNS query corresponds to a requested resource associated with a first resource identifier and wherein the first DNS server corresponds to the service provider;
• and
• provide the client computing device with at least one of an identifier corresponding to a storage component for the requested resource based on supplemental request routing information not included in the first resource identifier or an alternative resource identifier query to resolve to a domain corresponding to the service provider, wherein the alternative resource identifier includes the supplemental request routing information not included in the first resource identifier.
