isäntälaitteiston
Isäntälaitteisto, often translated as host hardware or host system, refers to the physical computer or server that a virtual machine or other guest system runs upon. It provides the fundamental resources necessary for the guest to operate, including processing power (CPU), memory (RAM), storage (hard drives or SSDs), and network interfaces. The isäntälaitteisto is the bedrock upon which virtualization technologies are built.
The performance of the isäntälaitteisto directly impacts the performance of any guest systems running on it.
In many cloud computing scenarios, the isäntälaitteisto resides in large data centers, operated by service providers.
