Difference between Cloud Computing and Virtualization
  • Last Updated : 06 May, 2020

Cloud computing: Cloud computing is a bundle of principles and approaches to deliver compute, network, and storage infrastructure resources, services, platforms and applications to users on-demand across any network. These infrastructure resources, services, and applications are sourced from clouds, which are pools of virtual resources orchestrated by management and automation software so they can be accessed by users on-demand through self-service portals supported by automatic scaling and dynamic resource allocation.

Virtualization: Virtualization is a technology that allows creating multiple simulated environments or dedicated resources from a single, physical hardware system. Software called hypervisors connects directly to that hardware and allows you to split 1 system into separate, distinct, and secure environments known as Virtual machines(VMs). These VMs rely on the hypervisor’s ability to separate the machine’s resources from the hardware and distribute them appropriately.

Below is a table of differences between Cloud Computing and Virtualization:

Features Cloud Computing Virtualization
Basic Pool and automate virtual resources for on demand use Built multiple simulated environments from one physical hardware system
Scalability High Low
Set-up Tedious Simple
Cost Private Cloud : HIGH CAPEX and low OPEX
Public Cloud : Low CAPEX and high OPEX
High Capital expenditures (CAPEX)
low Operating Expenses (OPEX)
Flexibility Very flexible Quite less
Type of service laas Saas
Dedicated hardware Multiple Single can also work
Integration Future expansion of users, application, etc Expansion of new machines within the same infrastructure
Workload stateless Stateful
Disaster recovery Depends on multiple machines Depends upon the single machine
Form Private and Public cloud Hardware and application virtualization
Accessibility Prevalently accessed Not allowed to be accessed from outside the network
