ESB and Enterprise Architecture

Logical and Physical architecture:

The logical architecture is a more detailed structure defines what has to be done to support the user services. It defines the processes that perform functions and the information or data flows that are shared between these processes. Logical architecture do not include physical server names or addresses. They do include any business services, application names and details, and other relevant information for development purposes.



A physical architecture has all major components and entities identified within specific physical servers and locations or specific software services, objects, or solutions. Include all known details such as operating systems, version numbers, and even patches that are relevant. Any physical constraints or limitations should also be identified within the server components, data flows, or connections. This design usually precludes or may be included and extended by the final implementation team into an implementation design.
