Abstract

A system, method, and computer readable medium for managing CDN service providers are provided. A network storage provider storing one or more resources on behalf of a content provider obtains client computing device requests for content. The network storage provider processes the client computing device requests and determines whether a subsequent request for the resource should be directed to a CDN service provider as a function of the updated or processed by the network storage provider storage component.

Claims

1. A computer-implemented method comprising:

under control of a hardware computing device configured with specific computer executable instructions;

obtaining, at a first DNS server, a first domain name system (DNS) query from a client computing device associated with a first point of presence (POP), wherein the first DNS query is associated with a requested resource, wherein the requested resource is associated with a content provider and wherein the first DNS server is associated with a content delivery network (CDN) service provider that is different from the content provider;

determining whether the content provider has exceeded a threshold network usage, wherein the threshold network usage is determined based at least in part on content provider pricing information, wherein the content provider pricing information indicates a price at which the CDN service provider provides content on behalf of the content provider;

selecting an alternative resource identifier associated with a second DNS server at a second POP of the CDN service provider or an internet protocol (IP) address of a cache component at the second POP if the content provider is determined to have exceeded the threshold network usage, wherein the alternative resource identifier includes information for causing a second DNS query to resolve to the second DNS server of the CDN service provider; and

transmitting, to the client computing device, the selected alternative resource identifier or the IP address.

2. The computer-implemented method of claim 1, wherein determining whether the content provider has exceeded a threshold network usage comprises:

obtaining the threshold network usage for the content provider; and

comparing current network usage data for the content provider with the threshold network usage.

3. A computer-implemented method comprising:

under control of a hardware computing device configured with specific computer executable instructions;

obtaining, at a first domain name system (DNS) server, a DNS query from a client computing device associated with a first point of presence (POP), wherein the DNS query is associated with a requested resource, wherein the requested resource is associated with a content provider and wherein the first DNS server is associated with a content delivery network (CDN) service provider;

selecting an alternative resource identifier associated with a second DNS server at a second POP or an internet protocol (IP) address of a cache component at the second POP upon determining that the content provider has exceeded a threshold network usage, wherein the threshold network usage is determined based at least in part on content provider pricing information; and

transmitting, to the client computing device, the selected alternative resource identifier or the IP address.

4. The computer-implemented method of claim 3, wherein the alternative resource identifier includes information for causing a second DNS query to resolve to the second DNS server of the CDN service provider.

5. The computer-implemented method of claim 3, wherein the alternative resource identifier is selected.

6. The computer-implemented method of claim 3 further comprising:

obtaining a second DNS query from the client computing device at the second DNS server, wherein the second DNS query is associated with the alternative resource identifier provided by the CDN service provider and wherein the second DNS server is associated with the CDN service provider;

selecting a cache component for providing the requested resource; and

transmitting, to the client computing device, information identifying the selected cache component.

7. The computer-implemented method of claim 3, wherein the alternative resource identifier is associated with a CNAME.

8. The computer-implemented method of claim 3, wherein the CDN service provider is different from the content provider.

9. The computer-implemented of claim 3, wherein the content provider pricing information indicates a price at which the CDN service provider provides content on behalf of the content provider.

10. The computer-implemented method of claim 3, wherein the content provider pricing information comprises a pricing structure for the CDN service provider to provide content on behalf of the content provider.

11. The computer-implemented method of claim 10, wherein the pricing structure is associated with a flat-rate price, wherein the threshold network usage is determined at least in part on a network usage of the content provider corresponding to the flat-rate price.

12. The computer-implemented method of claim 3, wherein selecting an alternative resource identifier associated with a second DNS server at a second POP or an internet protocol (IP) address of a cache component at the second POP is further based at least in part on a threshold content delivery bandwidth associated with the second POP.

13. A system comprising:

a first point of presence (POP) associated with a content delivery network (CDN) service provider, wherein the first POP includes a first domain name system (DNS) server that receives a first DNS query from a client computing device, wherein the DNS query is associated with a requested resource, wherein the requested resource is associated with a content provider, and wherein the first DNS server is operative to;

determine whether the content provider has exceeded a threshold network usage, wherein the threshold network usage is determined based at least in part on content provider pricing information;

select an alternative resource identifier associated with a second DNS server at a second POP of the CDN service provider or an internet protocol (IP) address of a cache component at the second POP if the content provider is determined to have exceeded the threshold network usage; and

transmit, to the client computing device, the selected alternative resource identifier or the IP address.

14. The system of claim 13, wherein the alternative resource identifier includes information for causing a second DNS query to resolve to the second DNS server of the CDN service provider.

15. The system of claim 13, wherein the alternative resource identifier is selected.

16. The system of claim 15 further comprising:

the second POP associated with the CDN service provider, wherein the second POP includes the second DNS server that receives a second DNS query from the client computing device, wherein the second DNS query is based on the determined alternative resource identifier, and wherein the second DNS server is operative to;

select a cache component for providing the requested resource; and

transmit, to the client computing device, information identifying the selected cache component.

17. The system of claim 13, wherein the content provider pricing information indicates a price at which the CDN service provider provides content on behalf of the content provider.

18. The system of claim 13, wherein the content provider pricing information comprises a flat-rate price for network usage at which the CDN service provider provides content on behalf of the content provider.

19. The system of claim 18, wherein the threshold network usage is determined at least in part on a network usage corresponding to the flat-rate price.

20. The system of claim 13, wherein selecting an alternative resource identifier associated with a second DNS server at a second POP or an internet protocol M address of a cache component at the second POP is further based at least in part on a threshold content delivery bandwidth associated with the second POP.
