Virtualization vs Cloud Computing: What's the Difference?

 

What is Virtualization?

Virtualization is a technology that allows a single physical machine to run multiple virtual machines (VMs) using software called a hypervisor. Each virtual machine works like an independent system with its own operating system and applications. The main goal of virtualization is to use hardware resources efficiently.

What is Cloud Computing?

Cloud computing is a service model that provides computing resources such as servers, storage, databases, and applications over the internet. Users can access these resources on demand without owning or managing physical hardware. Cloud computing uses virtualization as its base but adds flexibility, scalability, and remote access.

Key Differences Between Virtualization and Cloud Computing

• Nature: Virtualization is a technology, while cloud computing is a service delivered over the internet.
• Purpose: Virtualization focuses on creating virtual environments on physical hardware. Cloud computing focuses on delivering IT resources to users on demand.
• Scalability: Virtualization has limited scalability based on hardware capacity. Cloud computing allows easy scaling up or down as needed.
• Accessibility: Virtualized systems are usually managed internally. Cloud services can be accessed from anywhere through the internet.
• Dependency: Cloud computing depends on virtualization, but virtualization can exist without cloud computing.

How Virtualization Supports Cloud Computing

Virtualization forms the foundation of cloud computing by enabling the creation of virtual servers, storage, and networks. Cloud providers use virtualization to offer shared resources to multiple users efficiently.

Virtualization and cloud computing are closely related but serve different purposes. Virtualization creates virtual systems, while cloud computing delivers those systems as scalable services. Understanding their differences helps businesses choose the right technology for their needs.
