What is VPS/VDS?

VPS/VDS, in its simplest form, is a virtual server. It is obtained by dividing a physical server into multiple "small" servers using specialized software.

Although the basic principle involves creating many smaller servers from a single server, different results are achieved when different software is used for partitioning.

What is a VPS (Virtual Private Server)?

A VPS is obtained by the software-based partitioning of the main server. In this virtualization system, all VPSs on that server must use the operating system installed on the main server, and they operate as small particles dependent on this operating system. Since all processor and RAM sharing is done through software in this virtualization system, if there is an issue on the server (such as one VPS using excessive CPU or RAM, or facing an attack), all VPSs on the server are affected. The amount of RAM allocated to VPSs can be shared among them, meaning that unused RAM from one VPS can be allocated to another. While all VPSs operate independently, they are all components of the same whole. Although high performance is achieved across the system, certain operations like kernel updates may not be possible.

What is a VDS (Virtual Dedicated Server)?

A VDS is obtained by the hardware-based partitioning of the main server. VDSs that are virtualized in this way become entirely independent small servers. Each may have a different operating system, and their resource usage is entirely independent of each other. The allocated CPU and RAM are not shared with others. Therefore, VDSs do not impact each other; a VDS experiencing excessive resource usage or being attacked will not affect others. In terms of operation, there is no difference from a physically leased server, and all kinds of operations, including kernel updates, can be performed.
