With the ESB Toolkit you use Resolvers to dynamically set maps and endpoints and you get several Resolvers out of the box. The BizTalk ESB Toolkit includes the following resolvers: STATIC, UDDI, UDDI3, XPATH, BRE, BRI, ITINERARY, ITINERARY-STATIC and LDAP. When you set an endpoint in an Itinerary with the STATIC Resolver you are able to reuse Orchestration Services and Messaging Services (pipeline components) to call other web services but it’s also not ideal to store an endpoint in an itinerary because often you have other web services in your development environment than in test, acceptance and production. In that case you have to create different itineraries for all environments. In larger environments where you have a lot of services you want to have a repository to store and manage the web services. Microsoft created UDDI for that but it’s not commonly used because it’s quite complex. Microsoft partner, Nevatech offers Sentinet software product that provides SOA implementations with design-time governance and runtime management. Combined with the free Sentinet BizTalk Server Extensions you can also use it in combination with the ESB Toolkit.
