The application server needs to have:
- RAM: 512 MB+.
- CPU: At least dual-core to run both server/worker.
- HDD: Depends on your needs, but at least 2 GB to install the app and dependencies.
Keep in mind that the more users you have, the better server you will need.
Besides, some SciNote functions, such as Microsoft Office Online, cannot work when SciNote is installed locally. In this case, if you want Microsoft Office Online to work you need to have Microsoft Exchange Server and some configuration is needed on your end as well.
