With many other VPS plans, they cut off and limit your resource usage. Our Cloud VPS plans are different in the sense that they offer Burstable RAM limits. You will have a dedicated amount of RAM during low traffic periods (1.5GB for Cloud VPS-1000, 3GB for Cloud VPS-2000 and 6GB for Cloud VPS-3000), but are able to use a higher amount during high traffic surges and spikes.
The fun part starts when you try to secure your server. I configured CSF (ConfigServer Security & Firewall) and cPHulk Brute Force Protection to make sure the server is secure. As i am responsible for the security of my own server, i am always having to spend valuable time to stop any attack or hacks. I usually get notifications of hackers trying to get in but the server hardening work has made it impossible to hack. The only thing is, now, i wouldn't mind paying the extra to get a managed server so i can use the time elsewhere.
