The advantage of a VPS is that you don’t have to worry about hardware management
— so you would not need to monitor the status of the physical server, i.e. temperature, power, etc.
They are adapted to host most types of web projects that are moderately sized.
A dedicated server is recommend if you want to manage the hardware aspects yourself,
build more elaborate architectures, create an infrastructure that includes a private network (vRack),
and deploy other complex solutions that are not web services.
As a general rule, users with a growing volume of web activity either move up to dedicated servers,
or Public Cloud solutions. These services offer more complex, flexible infrastructures that can adapt to
a high level of growth.
