A
Virtual Private Server (VPS) is a virtual machine that is emulated on a
dedicated host with the
help of a hypervisor such as
KVM. More than one VPS sits on a single dedicated host in cloud VPS environments. And
multiple VPS share all resources such as RAM, CPU, and storage. It also causes
resource congestion which can lead to websites and applications performing badly. A Virtual System is also a
Smart Dedicated Server. But the difference is that only one
virtual machine is sitting on a dedicated host. Therefore, all the resources are
dedicated to this one
single VM. Therefore, an SDS is highly reliable and guarantees good performance.
