Cloud Computing and Virtualization - An Insight Story

Cloud computing and server virtualization are two concepts that are often confused and yet very distinct. Simply put cloud computing is a service that relies on server virtualization, which is technology.

Let's first learn the basics of Server Virtualization

The server virtualization is to create several virtual independent servers from one physical server. This technology optimizes the resources of each server by creating a separate environment or dedicated resources.

Server virtualization can be carried out within the company, in its own data centers. But this technology makes it possible to facilitate the outsourcing of its hosting.

Although it is still possible to host physical servers with a service provider, the added value of server virtualization is that it can somehow transform a server into a large file containing the operating system, applications, and/or the data. It is therefore more easily "movable".

By moving it to the data center of a digital service provider, the company benefits from more flexibility and scalability, the hardware infrastructure of a host is generally robust and imposing than those of most SMEs.

Virtualized hosting has indeed greatly contributed to a fundamental change in the management of information systems in following manners:

  • By limiting material investment expenses.
  • By allowing companies to benefit from the advantages of a dedicated environment without having to manage the technical and operational constraints.

Cloud Computing

Cloud computing can be defined as a set of virtual resources stored on servers and accessible on demand. There are two types of cloud computing -

The public cloud:  This solution consists of hosting data on industrial data centers and publicly accessible from any terminal connected to the internet.
The private cloud:  This solution consists of hosting its data on servers dedicated to the needs of a single company and physically installed generally in a specialized data center.

The cloud is, therefore, a service. The main characteristic of cloud computing is to be reactive and adaptable to the needs of each information system. To choose your cloud service, you will have to make strategic choices

Since the cloud is based on server virtualization, it benefits from all the advantages of this technology such as dematerialization of the infrastructure, the reactivity of implementation, high availability of data, high scalability of the solution, and increased security.

To properly choose the degree of outsourcing that your information system needs, it is imperative to fully grasp all of the concepts and issues that arise from it.
