Guidelines for Selecting the Server Node

Hi Team, Is there any predefine guidelines in selecting the App node server for application. when do i select S21 and when do I select M21, I would like to know how to recommend the nodes based on the no of users, concurrency and microflow load.

No there are no guidelines. Because it is not only dependent on the number of concurrent users but also what they do in the model and how big your model is. I would start with small because you can easily upgrade if during the first usage you notice that the environment in to small. Just watching the metrics for a couple of days will already give you the info about the usage of your app. And upgrading is always easier then downgrading. And those upgrades can be done fast by Mendix.
