CLOUD COMPUTING AND VIRTUALIZATION: CAN CLOUD COMPUTING EXIST SEPARATELY FROM VIRTUALIZATION?

Abstract

Virtualization is a software technique that emulates the operation of the entire computer. Depending on the needs
and the powers of the physical computer, several virtual machines can be installed at the same time. The resources
of physical computers will be shared between all virtual machines and because of that, virtual machines will be
working slower. A virtual machine uses a combination of software and an existing computer to provide additional
computer machines, all in one physical device. Cloud computing involves delivering hosted services and cloud
applications over the internet and enables users to obtain a shared pool of data from remote physical servers,
databases, and computers. Although virtualization and cloud computing are seen as two different techniques, they
are interconnected and cannot exist without each other. Virtualization in cloud computing can prevent the IT
system from failing and can protect the IT environment from bugs and viruses. In IT infrastructure, cloud
computing and virtualization are used together to build a cloud infrastructure. The aim of this study is to define
and analyze what virtualization and cloud computing are. Then through a comparison to show how these
techniques are related to each other and consequently a conclusion will be drawn.
