Since my situation seems to fit Filemaker's definition of “Solution Bundle Hosting” https://www.filemaker.com/company/legal/docs/hosting_faq.pdf I think the best course of action is to provide hosting for my clients. This way I can provide the low price of shared hosting for the foreseeable future.
I am totally new to Filemaker server and servers in general. I will approach the subject as I approach any new subject: online research, some books from amazon, perhaps a Lynda course -- covering servers, filemaker server, and whatever else seems relevant.
However I was wondering, does the community have any sage advice to help a neophyte? Do some of you think it is not feasible for someone to go from totally ignorant to running filemaker server 24/7 in a matter of months?
