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

incrementally change availability of a feature of a software service to one or more clients over a network based on a configuration setting indicating a proportion of the one or more clients that is eligible to receive the feature, the eligibility of a respective client of the one or more clients based, at least in part, on a respective client rank, the respective client rank based, at least in part, on a respective client identification, that identifies the respective client, and a feature identification, that identifies the feature, that are combined to generate a respective combined client identification and feature identification; and

generate the respective client rank based, at least in part, on the respective combined client identification and feature identification;

determine whether access to the respective client identification exists;

responsive to determining access to the respective client identification exists, generate the respective client rank based, at least in part, on combining the respective client identification with the feature identification to generate a respective combined client identification with the feature identification value; and

responsive to determining access to the respective client identification does not currently exist for at least one client, generate the respective client rank by assigning a random number as the respective client rank.

2. The one or more computer-readable storage media hardware as described in claim 1, wherein the configuration setting is adjustable to increase or decrease the proportion of clients that is eligible to receive the feature.

3. The one or more computer-readable storage media hardware as described in claim 2, wherein the configuration setting is set to an initial value to deploy the feature to an initial proportion of the clients and is thereafter increased over time to deploy the feature to an increasing proportion of the one or more clients.

4. The one or more computer-readable storage media hardware as described in claim 2, wherein the configuration setting is decreased from a first value to a null value in response to detecting a failure associated with the feature and is thereafter increased from the null value to an increased value to deploy the feature to an additional proportion of the one or more clients.

5. The one or more computer-readable storage media hardware as described in claim 1, further comprising processor-executable instructions that are configured to:

compare the respective client rank with the configuration setting to determine if the respective client is eligible to receive the feature.

6. The one or more computer-readable storage media hardware as described in claim 1, wherein the processor-executable instructions to generate the respective client rank are further configured to:

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

subject the hash value to a modulo operation to generate the respective client rank.

7. The one or more computer-readable storage media hardware as described in claim 1, further comprising processor-executable instructions that are configured to compare the respective client identification of each of the one or more clients with a list of clients, the list of clients indicating for selected clients of the one or more clients whether the selected clients are one of eligible to receive the feature or ineligible to receive the feature regardless of the respective client ranks of the select clients.

8. The one or more computer-readable storage media hardware of claim 1, wherein the processor-executable instructions are further configured to receive the respective client identification from an authentication procedure associated with the respective client.

9. The one or more computer-readable storage media hardware of claim 1, wherein the processor-executable instructions are further configured to obtain the configuration setting from a configuration file.

10. A computer-implemented method comprising:

incrementally changing availability of a feature of a software service to one or more clients over a network based, at least in part, on;

a configuration setting indicating a proportion of the clients of the one or more clients that is eligible to receive the feature, the configuration setting configurable to;

increase or decrease the proportion of clients that is eligible to receive the feature; and

prevent the feature from being made available to the clients by utilizing a null value; and

a respective client rank of each respective client of the one or more clients, the respective client rank based, at least in part, on a respective client identification that identifies the respective client and a feature identification that identifies the feature of the software service,

the changing the availability comprising;

determining whether access to the respective client identification exists;

responsive to determining access to the respective client identification exists, generating the respective client rank based, at least in part, on combining the respective client identification with the feature identification; and

responsive to determining access to the respective client identification does not currently exist, generating the respective client rank by assigning a random number as the respective client rank.

11. The computer-implemented method as described in claim 10, further comprising:

setting the configuration setting to an initial value effective to deploy the feature to an initial proportion of the clients; and

thereafter increasing the configuration setting over time to deploy the feature to an increasing proportion of the clients.

12. The computer-implemented method as described in claim 10, further comprising:

decreasing the configuration setting from a first value to the null value effective to prevent the feature from being made available to the clients; and

thereafter increasing the configuration setting from the null value to an initial value to deploy the feature to an initial proportion of the clients.

13. The computer-implemented method as described in claim 10, further comprising:

comparing the respective client rank with the configuration setting to determine if the respective client is eligible to receive the feature.

14. A system comprising:

at least one processor; and

one or more computer-readable storage media hardware comprising processor-executable instructions which, responsive to execution by the at least one processor, are configured to enable the system to;

incrementally change availability of a feature of a software service, provided by a service provider, to one or more clients over a network based on a configuration setting indicating a proportion of the one or more clients that is eligible to receive the feature, the eligibility of a respective client of the one or more clients based, at least in part, on a respective client rank, the respective client rank based, at least in part, on a respective client identification, that identifies the respective client, and a feature identification, that identifies the feature of the software service, the configuration setting being adjustable to increase or decrease the proportion of clients that is eligible to receive the feature,

the system further configured to;

determine whether access to the respective client identification exists;

responsive to determining access to the respective client identification exists, generate the respective client rank based, at least in part, on combining the respective client identification with the feature identification to generate a respective combined client identification with the feature identification value; and

responsive to determining access to the respective client identification does not currently exist, generate the respective client rank by assigning a random number as the respective client rank.

15. The system as described in claim 14 further comprising processor-executable instructions that are configured to:

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

subject the respective hash value to a modulo operation to generate the respective client rank.

16. The system as described in claim 15, wherein:

the modulo operation comprises an n modulo 100 operation, where n is the hash value, the configuration setting is a percentage between 0% and 100%, and the client rank is a value between 0 and 99.

17. The system as described in claim 14, wherein the processor-executable instructions are further configured to:

compare the respective client identification of each respective client of the one or more clients with a list of clients, the list of clients indicating for selected clients of the one or more clients whether the selected clients are one of eligible to receive the feature or ineligible to receive the feature regardless of the client ranks of the select clients.

18. The system as described in claim 14 further configured to obtain the configuration setting from a configuration file, the configuration file comprising an Extensible Markup Language (XML) file.

19. The system as described in claim 14, wherein the system is further configured to:

allow a respective client of the one or more clients access to the feature based on the respective client identification being present in an add/block list, regardless of the respective client rank of the respective client.
