Difference between Cloud Computing and Virtualization
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:
|Basic||Pool and automate virtual resources for on demand use||Built multiple simulated environments from one physical hardware system|
|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|
|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.|
