Difference between Cloud Computing and Virtualization

Cloud computing: Cloud computing is a bundle of principles and approaches to deliver computer 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
Configuration	In Cloud Computing , Configuration is image based.	In Virtualization, Configuration is template based.
