Differences between virtualization and cloud computing
Cloud Computing
The Cloud Computing provides all that could offer a local computer system as a remote service.
Users only need a terminal (mobile or fixed) with internet access and connect to resources in the cloud contracted. This service saves investments in
servers and hardware and provide transparency in the management of these.
Virtualization
It is the creation (through software) of a virtual version of a resource of hardware, operating systems, storage devices and other network resources.
To understand the concept we can see this of a one only hardware running multiple operating systems simultaneously.
The most used solutions are VMware and Citrix.
Effects of virtualization and cloud computing in Datacenters
Decreased costs
Cloud computing offers advantages to small and medium enterprises in terms of cost reduction. You pay for what you use.
Virtualization reduces costs by leveraging the hardware much more.
Scalable Storage Options
Expansions quick and simple as needed.
Automatic updates
The CPD is responsible for updating
Remote acces
Mobility and easy access
More ecological
These data centers more energy advantage that the local installation of machinery.
Easer implementation
You can make your servers in the same time it takes to configure a Facebook account (for example).
Security
Use Cloud is always safer because they are prepared and conditioned against any security threats.
Other point is the security offered by virtualization, which allows us to easily replicate machines, useful in case of disaster or migration.
