Abstract

According to one general aspect, a method may comprise identifying a provider application that is associated with a consumer application, from amongst a plurality of provider applications hosted on a provider machine. In various embodiments, the identification may be based at least in part upon the provider application'"'"'s business identifier (ID). In various embodiments, each provider application includes at least one web service. In some embodiments, the plurality of provider applications includes a plurality of instantiations of at least one of the web service. In various embodiments, the method may also include transmitting a message to one of the web services of the identified provider application.

determining, by the consumer machine, a logical port address of a web service provided by the identified provider application using mapping information, the mapping information including a list of provider applications'"'"' business IDs, and, for each provider application'"'"'s business ID, one or more web services and corresponding logical port addresses associated with a respective provider application, wherein the determining includes selecting the provider application whose provider application'"'"'s business ID matches the received provider application'"'"'s business ID and selecting the logical port address for the web service associated with the selected provider application; and

transmitting a message to the web service of the selected provider application using the logical port address.

2. The method of claim 1 wherein identifying includes:

grouping a plurality of consumer communication proxies into a consumer service group;

associating the consumer service group with the provider application'"'"'s business ID; and

identifying the logical port address that includes the provider application'"'"'s business ID associated with the consumer service group using the mapping information.

3. The method of claim 1 wherein transmitting includes:

providing a consumer communication proxy with the message and the logical port address for the selected web service;

converting, by the consumer communication proxy, the message from a first format associated with the consumer application to a second format associated with the selected web service; and

transmitting, by the communication proxy, the message to the logical port address of the selected web service.

4. The method of claim 1 wherein transmitting includes asynchronously transmitting the message to the selected web service of the identified provider application.

5. The method of claim 1 wherein identifying includes:

selecting a provider application with which to communicate based on the type of business logic to be performed;

acquiring a set of provider applications and corresponding provider applications'"'"' business IDs with which the consumer application is associated;

determining which provider application, included in the set of provider applications, includes the provider application'"'"'s business ID of the selected provider application; and

selecting a web service of the determined provider application with which to communicate based on the mapping information.

6. The method of claim 1, wherein the service registry is centrally located with an Enterprise Service Architecture (ESA) landscape.

7. The method of claim 1, further comprising:

registering the provider application with the service registry including transmitting a registration message having the provider application'"'"'s business ID and at least one web service description language (WSDL) message defining a web service provided by the provider application.

8. The method of claim 1, wherein the plurality of provider applications includes a supplier relationship management (SRM) application, a product lifecycle management (PLM) application, and a supply chain management (SCM) application, and the selected provider application is one of the SRM application, the PLM application, and the SCM application.

9. The method of claim 1, wherein the plurality of provider applications includes a first provider application and a second provider application executing on a same provider machine, and the first provider application and the second provider application include substantially equivalent web services, and the selected provider application includes one of the first provider application and the second provider application.

10. An apparatus comprising:

at least one business logic function configured to perform logical operations on business data; and

at least one consumer communication proxy configured to;

transmit a request message, to a service registry remote from the apparatus, the request message including a business application identifier (ID) that substantially uniquely identifies the at least one business logic function, the request message requesting identification of one or more provider applications associated with the at least one business logic function among a plurality of provider applications hosted on a provider machine remote from the apparatus and the service registry, each provider application including at least one web service,

receive, from the service registry, at least one provider application'"'"'s business application identifier (ID) that is associated with the business application ID in response to the request message,

identify, based at least upon the provider application'"'"'s business application ID, a provider application from amongst the plurality of provider applications,

determine a logical port address of a web service provided by the identified provider application using mapping information, the mapping information including a list of provider applications'"'"' business IDs, and, for each provider application'"'"'s business ID, one or more web services and corresponding logical port addresses associated with a respective provider application, including selecting the provider application whose provider application'"'"'s business ID matches the received provider application'"'"'s business ID and selecting the logical port address for the web service associated with the selected provider application, and

transmit a message to the web service of the selected provider application using the logical port address.

11. The apparatus of claim 10,

wherein the apparatus includes a plurality of consumer communication proxies,

wherein the apparatus is configured to group a plurality of consumer communication proxies into a consumer service group, and associate the consumer service group with the provider application'"'"'s business application ID.

12. The apparatus of claim 10, wherein the consumer communication proxy is configured to convert the message from a first format associated with the at least one business logic function to a second format associated with the selected web service, and transmit the message to the logical port address of the selected web service.

13. A computer program product, comprising a non-transitory computer-readable medium having executable instructions by at least one processor, the executable instructions configured to:

transmit a request message, from a consumer machine to a service registry remote from the consumer machine, the request message including a business application identifier (ID) that substantially uniquely identifies a consumer application executed by the consumer machine, the request message requesting identification of one or more provider applications associated with the consumer application among a plurality of provider applications hosted on a provider machine remote from the consumer machine and the service registry, each provider application including at least one web service;
