The document provides an overview of the integration between the Homeserve USA HS Business application and the Ensura ERP system using Talend ESB. Talend ESB acts as an intermediate message transfer service, facilitating requests from the HS Business application to the Ensura application and responses back. A number of services are described for the ESB including contract, customer, partner, payment, sale and more. SoapUI NG and LoadUI NG will be used for functional testing, data driven testing, and load/performance testing of the services.
