If there is no local web server available to host these services, then the follow-
ing alternative configurations can be utilized:
• If the VMS is standalone, then the VMS Server can host the Web
services and applications.
• If the VMS is redundant, then another local server must host the Web
services and applications in order to retain true redundancy.
Requests and responses transmitted between the web application and the web
service use SOAP over HTTP protocol. The SOAP request is translated into an
RPC call into the VOS and the response is then returned to the web application.
This response is transformed into HTML and sent back to a web browser that
presents the user interface to the operator.
