Abstract

A system, method and computer-readable medium for request routing. A DNS server at a content delivery network service provider obtains a DNS query corresponding to a resource requested from a client computing device and associated with a first resource identifier. The first resource identifier includes a first portion with DNS information and a second portion with path information. The DNS server selects a network computing component for processing the requested resource based on the DNS portion of the resource identifier and transmits information identifying the selected network computing component to the client computing device.

Claims

1. A method for request routing comprising:

obtaining 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 a content delivery network service provider;

selecting a network computing component for processing the requested resource from a plurality of network computing components based on an application identifier included in the first resource identifier; and

transmitting information identifying the selected network computing component from the first DNS server to the client computing device;

wherein the network computing component is operable to dynamically cause the creation of an instance of a virtual machine for processing the requested resource.

2. The method as recited in claim 1, wherein the network computing component comprises an application for processing the requested resource.

3. The method as recited in claim 1, wherein the application is a data streaming application.

4. The method as recited in claim 1, wherein the first resource identifier includes a first portion for identifying information associated with a service plan provided by an original content provider and wherein a network computing component is selected based on the first portion.

5. The method as recited in claim 1, wherein the first resource identifier includes a first portion for identifying information associated with the file type of the requested resource and wherein a network computing component is selected at the first DNS server based on the file type.

6. The method as recited in claim 1, wherein the first resource identifier includes a first portion for identifying information associated with network computing component selection information, wherein the selection information includes quality of service information.

7. The method as recited in claim 1, wherein selecting a network computing component is further based on information associated with the geographic location of the client computing device.

8. The method as recited in claim 1, wherein selecting a network computing component is further based on performance metrics associated with one or more network computing components.

9. A method for request routing comprising:

obtaining 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 a content delivery network service provider;

selecting a network computing component for processing the requested resource from a plurality of network computing components, wherein the first resource identifier includes a DNS portion and a path portion, wherein the DNS portion includes a file identifier and wherein selecting the network computing component is based on the file identifier included in the DNS portion of the first resource identifier; and

transmitting information identifying the selected network computing component from the first DNS server to the client computing device;

wherein the network computing component is operable to dynamically cause the creation of an instance of a virtual machine for processing the requested resource.

10. A system for request routing comprising:

a first network point of presence associated with a content delivery network 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 is operable to;

select a network computing component for processing the requested resource from a plurality of network computing components based on an application identifier included in the first resource identifier; and

transmit information identifying the selected network computing component from the first DNS server to the client computing device;

wherein the network computing component is operable to dynamically cause the creation of an instance of a virtual machine for processing the requested resource.

11. The system as recited in claim 10, wherein the network computing component comprises an application for processing the requested resource.

12. The system as recited in claim 10, wherein the application is a data streaming application.

13. The system as recited in claim 10, wherein the first resource identifier includes a first portion for identifying information associated with a service plan provided by an original content provider and wherein the selection of the network computing component by the DNS server is further based on the first portion of the first resource identifier.

14. The system as recited in claim 10, wherein the first resource identifier includes a first portion for identifying information associated with the file type of the requested resource and wherein the selection of the network computing component by the DNS server is further based on the file type.

15. The system as recited in claim 10, wherein the first resource identifier includes a DNS portion and a path portion, wherein the DNS portion includes a file identifier and wherein the selection of the network computing component by the DNS server is further based on the file identifier included in the DNS portion of the first resource identifier.
