Yes. Jamf is an MDM. There are many. In no particular order or preference, others include Intune (from Microsoft), Mosyle, Jamf Now, Airwatch, MobileIron, Apple Business Essentials, and many more. Ideally, you will need the following:
• Sign up for Apple Business Manager (this is not Apple Business Essentials as Essentials is the Apple MDM while ABM is the chain of custody asset system
• Select and MDM
• Link your ABM to your reseller(s) (or Apple if you buy direct) so all new hardware is automatically assigned to ABM at time of purchase
• Define an MDM in ABM and set the assets to auto-assign to the MDM at time of ABM assignment
• Craft a process for managing existing devices - again, can be done without system wipe but you will not have the highest level of management.
• Craft an automated enrollment process
As for tutorials, Jamf offers the 100 classes for free on their website. Higher levels of certification are available but you need to take the classes. https://www.jamf.com/training/online-training/100/.
However, if you are buying directly from Jamf, you will need to perform a Jumpstart. This is a multi-day consulting engagement where Jamf will train you on the product. macOS and iOS are included. And if you need more, Jamf does offer onboarding services. The Jumpstart is to train you on the product, not to setup your specific environment. Onboarding services will setup your environment. I will assume these are both available in your region.
As for Apple Business Manager, you can initiate the sign up without calling Apple. https://business.apple.com/#/enrollment/form. You will need a person who can enter into legal contracts to be involved into the process and Apple will call you to ask a series of questions. Pro tip. Once you have ABM setup, make sure you create at least two admin accounts.
Again, the MDM solution will provide initial deployment, OS patching, app patching, app settings, restrictions, printers, etc. If you want a remote support tool, that remains an independent initiative.
Hope this helps you on your journey.
