Abstract: A computer-implemented technique is described herein for monitoring a web application that runs on plural computing machines provided by a network-accessible system. The technique involves determining a set of application instances that are assessed as healthy by the system, generating addresses for those application instances, and then testing the application instances in the set using their respective addresses. Overall, the technique can be considered to employ an “outside-in” strategy insofar as it interacts with the system from the vantage point of an end user.

Abstract: A schema browsing system is described herein that allows a user to quickly consume information about one or more XML schema elements of a schema set that the user is interested in and to visualize relationships of other elements to the elements of interest, irrespective of how the elements are physically stored and subdivided in XSD or other schema files. The system displays elements selected by the user and excludes portions of the schema set that are not related to the displayed elements. The system displays the selected elements along with a visual indication of the relationships between the selected elements. By repeating the process of selecting elements, the user can use the system to build up a display that includes only those elements and relationships in which the user is interested.
