I have a MacPro and a rented CloudLinux dedicated server with +20 domains. My question is, is it wise to replace CloudLinux with the OSX Server app? My reasons Using MacPro more logically. She is wasting as an in-office server. I want to own my own dedicated server, not a rented one. OSX Server's built-in services like calendar, contacts, time machine, XCode. This choise will reduce my costs to ~%50. If I want to rent a dedicated linux server as powerful as my MacPro, I will need to pay ~3 times more than I pay now. I'm used to use OSX rather than Linux My unrest points Linking osx server with non-native servers/services like MySQL is hard and complicated as I know. You cannot find help/resource about osx server easily when you need. I tried OSX Server once, ~3 years ago I love using MacPro in office We're using MAMP for development, and we like it. (Wow. I think MAMP is my 3rd option ) Security/Reliability etc. Services/Applications/Servers I generally use mySQL (Generally) PostgreSQL (not likely) Wordpress (not likely) IMAP/POP3 (I know OSX Server has these but I suffered trying to setup when I tried long ago) Composer and some more PHP stuff (I cannot remember now) XMPP (will use in 6 months) (Can I use OSX Server's Messages service) VOIP (will use in 1 year) We may create JAVA based Web Apps Git (may create as replacement of BitBucket for office use) These are all I come up with for now. Thanks for help.
