I was wondering if I could install SharePoint Workflow manager in one of the Servers where SharePoint 2013 is installed. I couldn't find an example if this kind of infrastructure was possible. All guides had a stand alone server for Workflow manager. If this is possible, which server would be appropriate for the installation WFE server of APP services server ?
Yes of course you can and the this article recommends you to be considered on both these scenarios.
- Is Workflow Manager installed on a server that is part of the SharePoint farm?
- Will communication between Workflow Manager and SharePoint Server 2013 use HTTP or HTTPS?
Yes, you can install on an existing SharePoint server or on a dedicated server.
