Abstract

Techniques are described to incrementally change the availability of a feature of a software service to clients over a network based on a configuration setting indicating the proportion of the clients that is eligible to receive the feature. In an implementation, a client rank is generated for a client on the network based on a client identification that identifies the client and a feature identification that identifies the feature. The feature may then be made available to the clients via the network if a comparison of the client rank with the configuration setting indicates that the client is eligible to access the feature.

Claims

1. A computer-implemented method comprising:

generating, using the computer, a client rank for a client based on a client identification that identifies the client and a feature identification that identifies a feature of a software service configured to be provided via a network, the generating comprising;

combining the client identification and the feature identification to form a combined client identification and feature identification;

subjecting the combined client identification and feature identification to a hash function to generate a hash value; and

subjecting the hash value to a modulo operation to generate the client rank;

comparing, using the computer, the client rank with a configuration setting, the configuration setting indicating a proportion of clients that is eligible to access the feature; and

making, using the computer, the feature available to the client via the network if the client rank indicates that the client is eligible to access the feature.

2. A method as described in claim 1, further comprising adjusting, using the computer, the configuration setting to increase or decrease the proportion of clients that is eligible to receive the feature.

3. A method as described in claim 1, wherein subjecting the hash value to the modulo operation comprises subjecting the hash value to an n modulo 100 operation, where n is the hash value.

4. A method as described in claim 3, wherein the configuration setting comprises a percentage between 0% and 100% and the client rank comprises a value between 0 and 99.

5. A method as described in claim 1, wherein comparing the client rank with the configuration setting comprises determining if the client rank is less than or equal to the configuration setting.

6. The computer-implemented method of claim 1, wherein the feature identification comprises a text string.

7. A system comprising:

one or more hardware processors;

one or more computer-readable storage media hardware;

a module embodied on the one or more computer-readable storage media hardware, the module embodying instructions that are executable by the one or more hardware processors, the module configured to;

receive a configuration setting that indicates a proportion of clients on a network that is eligible to receive a feature of a software service configured to be provided via the network, the configuration setting is adjustable to increase or decrease the proportion of clients that is eligible to receive the feature;

generate a client rank for a client on the network based on a client identification that identifies the client and a feature identification that identifies the feature, by;

combining the client identification with the feature identification to generate a combined client identification and feature identification;

subjecting the combined client identification and feature identification to a hash function to generate a hash value; and

subjecting the hash value to a modulo operation to generate the client rank; and

make the feature available to the client via the network if a comparison of the client rank with the configuration setting indicates that the client is eligible to access the feature.

8. The system of claim 7, wherein the module is further configured to:

retrieve at least two configuration settings;

determine a span of values based, at least in part, on the at least two configuration settings; and

make the feature available to the client via the network if the client rank falls within the span of values.

9. The system of claim 7, wherein the client identification comprises a globally unique identifier (GUID).

10. One or more computer-readable storage media hardware comprising computer-executable instructions which, responsive to execution by at least one processor, are configured to:

generate a client rank for a client based on a client identification that identifies the client and a feature identification that identifies a feature of a software service configured to be provided via a network, the instructions to generate the client rank further comprise instructions configured to;

combine the client identification and the feature identification to form a combined client identification and feature identification;

subject the combined client identification and feature identification to a hash function to generate a hash value; and

subject the hash value to a modulo operation to generate the client rank;

compare the client rank with a configuration setting, the configuration setting indicating a proportion of clients that is eligible to access the feature; and

make the feature available to the client via the network if the client rank indicates that the client is eligible to access the feature.

11. The one or more computer-readable storage media hardware as described in claim 10, wherein the instructions are further configured to generate an add/block list of clients configured to indicate select clients, of one or more clients, that are ineligible to receive the feature of the software service, regardless of an associated client rank of the select clients.

12. The one or more computer-readable storage media hardware as described in claim 10, wherein the instructions are further configured to adjust the configuration setting to increase or decrease the proportion of clients that is eligible to receive the feature.

13. The one or more computer-readable storage media hardware as described in claim 10, wherein the instruction configured to subject the hash value to the modulo operation are further configured to subject the hash value to an n modulo 100 operation, where n is the hash value.

14. The one or more computer-readable storage media hardware as described in claim 13, wherein the configuration setting comprises a percentage between 0% and 100% and the client rank comprises a value between 0 and 99.

15. The one or more computer-readable storage media hardware as described in claim 10, wherein the instructions configured to compare the client rank with the configuration setting are further configured to determine if the client rank is less than or equal to the configuration setting.

16. The one or more computer-readable storage media hardware as described in claim 10, wherein the computer-executable instructions are further configured to make the feature available to the client via a webpage.
