Database Virtualization Concepts

Introduction

Database virtualization is a technology that allows you to create a virtual version of a database, enabling multiple environments to run on a single physical server. This approach can lead to improved resource utilization, easier management, and enhanced flexibility in database deployment.

Key Concepts

Definitions

Virtualization: The process of creating a virtual version of something, including operating systems, servers, storage devices, and databases.
Database Virtualization: The abstraction of database resources from the physical hardware infrastructure, allowing multiple databases to share the same resources without interference.
