I just installed a Vanilla 9.1 instance as part of my upgrade process. I used the XP Scaled Topology, as I will need some of its features.

After installation, I found the following sites in IIS:

enter image description here

I can guess some of them - cd, cm, identityserver - but I'm at a loss for the others.


What is the function of the .collection, .ma, .mareporting, .prc, .processingEngine, .refdata, .rep, .reporting, .search websites in Sitecore 9.1?

  • All the roles are described here doc.sitecore.com/developers/91/… . I don't think copying that amount of content from official Sitecore documentation site is ok with their copyrights, so I will not include this as an answer. Mar 6, 2019 at 14:10

They are mostly self-explanatory, but here is the list of suffixes with the role names/descriptions:

  • *.cm: Content management server
  • *.cd: Content delivery server
  • *.collection: The xConnect collection server, collects contact and interaction data
  • *.identityserver: New in 9.1, this is the new Identity Server used for logging into the various other Sitecore admin pages
  • *.ma: Marketing Automation service
  • *.msreporting: Marketing Automation reporting server
  • *.prc: xDB Processing Service
  • *.processingEngine: xDB Processing Engine
  • *.refdata: Reference Data Service, Reference data includes things like event definitions.
  • *.rep: xDB Reporting
  • *.reporting: xDB Reporting Service
  • *.search: xConnect Search Indexer

For more detailed information about each role, the Sitecore documentation has a lot here: https://doc.sitecore.com/developers/91/platform-administration-and-architecture/en/roles-overview.html

  • Thank you Richard. As for the two xConnect instance, does their presence implies that xConnect is already installed as part of the XP1-SingleDeveloper.ps1 script? Mar 6, 2019 at 14:46

    Yes, that script should install an xConnect instance IIRC.
