Hypervisor

Meaning in cloud computing & devops, with examples

/ˈhaɪpərˌvaɪzər/nounCommon term

In cloud computing & devops, hypervisor means: Software that creates and runs virtual machines, sharing one physical computer's CPU, memory and storage between them and keeping them separate.

In Turkish: hipervizör, sanallaştırma katmanı
