Virtual Server (VPS/VDS)

Both VPS and VDS refer to virtual private server technology, which allows a single physical server to be divided into multiple independent virtual machines. In practice, these terms are often used interchangeably, and there is no difference between them.

Historically, VPS (Virtual Private Server) was more often associated with operating system-level virtualization (e.g., OpenVZ), where resources could be less isolated, while VDS (Virtual Dedicated Server) was associated with hardware virtualization (e.g., KVM, Xen), which provided more complete isolation and dedicated resources.

However, with advances in technology, modern providers almost always use hardware virtualization, regardless of whether they call their product VPS or VDS. Therefore, when choosing a service, it's more important to pay attention not to the name, but to the virtualization technology used (e.g., KVM), server specifications, and the provider's reputation.
