BENEFITS
DEDICATED vs. VPS
Dedicated
With dedicated servers you have full control of the whole server, the hardware and all sensors. The most applications do not need the power of a complete system but there might be applications which are very performance hungry or require access to physical devices.
VPS
Virtual Private Servers are hosted on a physical machine with heavy resources. CPU power is shared, but memory and HDD space are fixed. The virtualization layer offers a lot of flexibility, such as upgrading your CPU cores or memory just in time, sometimes even without a restart of your server.
