Hey there, those are great questions! First to answer your security questions. We're using KernelCare, which is like Ksplice. It keeps all our host kernels updated with no reboots needed.

OpenVZ, when used properly, provides us with massive performance gains along with the flexibility of "live scaling." Since we're providing containers, our customers can scale up to a larger plan with zero downtime. Their RAM and disk resources are available immediately after choosing the next package (additional cores require a reboot).
