In many ways a VPS server is relatively similar to a dedicated device. Both have dedicated resources that users can leverage, both are completely independent of other servers and both can provide powerful virtual server hosting options.
However, a recent Ars Technica report said dedicated servers differ from VPS plans because the virtual machine is directly tied to the physical device. At one time, the report said, this was an advantage because it meant they received an added layer of security. Now, VPS plans can keep virtual machines completely separate, giving the hosting plan unique advantages.
Because dedicated servers are tied to the physical device, hardware issues that arise can be difficult to deal with. While simple hardware failures may be addressed by quickly moving the virtual machine to a new physical device, the report said creating new server copies or migrating to a more powerful device can be challenging in dedicated plans.
None of these issues are relevant in VPS servers, according to the report, because a VPS is not inherently connected to the physical device.
According to a recent report from the Host Review, the separation between the physical device and virtual machine is even more apparent in cloud VPS hosting, which often allows complete freedom from physical devices.
