S4S can be installed on-premise, in hosted VMs, or in Azure PaaS. Some out-of-the-box features may be impacted by topology chosen. S4S has functionality to support Sitecore XP (SXP), and Email Experience Manager (EXM).
S4S is compatible only with Sitecore Experience Platform. S4S is not used with Sitecore Federated Experience Manager (FXM) or Sitecore Print Experience Manager (PXM). S4S libraries can be used by any ASP.NET application on the Sitecore server to programmatically access Salesforce.
Sitecore Versions
S4S releases are frequently published to support new Sitecore versions, new Salesforce API versions, implement extension functionality and fix bugs. For these reasons, you should strive to update S4S whenever conveniently possible.
