I just bought myself a dedicated server and already have 2 other VPS on different providers. I have a small 1 GB single core with 4 ips and 25GB storage VPS A 2 GB twin core with 3 ips and 50 GB VPS and now the new 8 core 4GB, 4 ips and 500 GB RAID Dedicated Server. All systems run Centos (2 x v7 and 1 x v6.5) (The VPS running V6.5 will be updated to V7) The 2 old VPSs are setup in a small cluster for the DNS etc I am thinking of instead of hosting sites on all of them, I would rather have the dedicated as the main hosting and use the VPS for seperate Mail, DNS, backup etc I am looking for some ideas and info regarding th best way to go about this, remembering that the 2 VPS are currently hosting a few sites that I'll need to move. My main aim is for security and performance. My thought at this stage is transfer all to the dedicated then then setup the 2 VPS for their new roles and then link all as required. Anyone done similar of is their any tutorials on muti server setups etc.?
