Commerce Connect needs to be installed on all servers used by either SCpbCS and SCpbMD, as both products build on top of Commerce Connect. For example, CM, CD, and processing servers.

SCpbCS	An extension to Sitecore Commerce Connect that exposes Commerce Server data to Sitecore. SCpbCS is made up of two packages, one package for the API level integration, and another for the Merchandising Manager tool. This Commerce Server Connect package is required on CM, CD, and processing servers.

SCpbMD
All packages	An extension to Sitecore Commerce Connect that exposes Microsoft Dynamics AX to Sitecore. This package is required on CM, CD, and processing servers.
Transaction Service	The runtime communication layer for that allows the Sitecore site to manage user and order data in Microsoft Dynamics AX. This service can be used with the Sitecore CM or CD servers, or as a standalone IIS service.
Routing service	Used to transfer catalog data from the Dynamics AX Channel database into Commerce Server Catalog. This service can run inside of Sitecore as a job, or externally as a console app or Windows service.

Microsoft Dynamics AX AOS Server	This should be installed on its own server in the internal network.
