Abstract

A method, computer program product, and data processing system for providing an improved directory service for storing information about hardware and software components is disclosed. The directory service stores not only the information that other hardware and software components require to locate, and make use of, the components listed in the directory, but is also able to dynamically construct ‘meta services’ that fulfill a client'"'"'s functionality requirements.

Claims

1. A computer-implemented process for storing information about hardware and software components comprising:

receiving a request containing a specified functional requirement for a service, wherein the specified functional requirement is in addition to current functional requirements for the hardware and software components deployed in a computing environment, wherein the request is made by a client;

consulting a directory to determine if a single component from the hardware and software components exists that satisfies the specified functional requirement for the service;

in response to a determination that the single component that satisfies the specified functional requirement does not exist, forwarding the request to a composition service;

determining, by the composition service, whether the specified functional requirement can be satisfied from a history database, wherein the history database stores previously-derived combinations of services;

in response to a determination that the composition service can not satisfy the specified functional requirement, employing a composition logic to identifying a plurality of derived functionalities that, when combined according to a combination method, would satisfy the specified functional requirement for the service;

identifying a plurality of components satisfying the plurality of derived functionalities; and

storing, information about the plurality of components satisfying the plurality of derived functionalities, into the history database, wherein the plurality of derived functionalities is equivalent to the specified functional requirement for the service.

2. The computer-implemented process of claim 1, further comprising:

verifying that the plurality of components is combinable.

3. The computer-implemented process of claim 1, the process further comprising:

returning the instructions to the client,

whereby the client may utilize the plurality of components to achieve the specified functional requirement.

4. The computer-implemented process of claim 1, the process further comprising:

providing the instructions to a remote meta-service provider so that the remote meta-service provider may provide functionality satisfying the specified functional requirement to the client by combining the plurality of components into a meta-service.

5. The computer-implemented process of claim 1, further comprising:

registering an identification of the plurality of components with the directory for future use without reidentifying the plurality of components.

6. The computer-implemented process of claim 1, further comprising:

registering an identification of the plurality of components with a plurality of directories for future use from multiple sources without reidentifying the plurality of components.

7. The computer-implemented process of claim 1, wherein the request is made by a client and the process further comprises:

making an identification of the plurality of components available to services other than the client.

8. The computer-implemented process of claim 1, wherein the request is made by a client and the process further comprises:

identifying a plurality of combinations of components satisfying the plurality of derived functionalities; and

offering the client a choice of a combination from the plurality of combinations.

9. The computer-implemented process of claim 8, wherein offering the client a choice of a combinations from the plurality of combinations further includes:

providing additional information regarding each of the plurality of combinations such that the client may utilize the additional information as selection criteria for choosing a combination from the plurality of combinations.

10. The computer-implemented process of claim 1, wherein the request is made by a client and the process further comprises:

identifying a plurality of combinations of components satisfying the plurality of derived functionalities;

querying the client to determine additional preferences; and

choosing, based on the additional preferences, at least one combination from the plurality of combinations to offer to the client.

11. A computer-readable storage medium storing a computer program product, the computer program product comprising functional descriptive material that, when executed by a computer, enables the computer to perform acts including:

receiving a request containing a specified functional requirement for a service, wherein the specified functional requirement is in addition to current functional requirements for the hardware and software components deployed in a computing environment, wherein the request is made by a client;

consulting a directory to determine if a single component from the hardware and software components exists that satisfies the specified functional requirement for the service;

in response to a determination that the single component that satisfies the specified functional requirement does not exist, forwarding the request to a composition service;

determining, by the composition service, whether the specified functional requirement can be satisfied from a history database, wherein the history database stores previously-derived combinations of services;

in response to a determination that the composition service can not satisfy the specified functional requirement, employing a composition logic to identifying a plurality of derived functionalities that, when combined according to a combination method, would satisfy the specified functional requirement for the service;

identifying a plurality of components satisfying the plurality of derived functionalities; and

storing information about the plurality of components satisfying the plurality of derived functionalities, into the history database, wherein the plurality of derived functionalities is equivalent to the specified functional requirement for the service.

12. The computer program product of claim 11, comprising additional functional descriptive material that, when executed by the computer, enables the computer to perform additional acts including:

verifying that the plurality of components is combinable.
