When editing documents, only a web end is required. As above, results are given for both the recommended Green Zone performance characteristics as well as upper limits specified by the Red Zone table.

Renders are then placed in the Web App cache. The details below give an indication of results for a topology where the web front ends and the app server back ends are changed (that is, a 1x2 would be one front end with two app servers, all supported by an instance of SQL Server). The user count is an estimate on the number of users that are actively viewing a document using the PowerPoint Web App that the topology could support.
