What is Cloud Computing?

Cloud Computing… You’ve probably heard this term before! But what is it, and what are the advantages for businesses to step toward Cloud migration?

At the heart of information technology, Cloud Computing is revolutionizing how we manage data and applications. By allowing access to computing resources via the Internet, without the need to manage physical underlying infrastructure, Cloud Computing offers flexibility and efficiency.

Cloud Computing: Basic Principles of the Cloud

The Cloud consists of servers distributed in data centres worldwide. These remote servers host, process, and manage massive amounts of data via the Internet, therefore replacing the physical servers traditionally used by businesses.

The fundamental distinction between Cloud Computing and traditional IT systems lies in how resources are managed and utilized.

Many businesses continue to purchase and manage their own physical infrastructure, including servers and software, a practice that can be costly and complex. The Cloud offers a flexible alternative, allowing for quick adaptation to technological changes without the constraints of physical infrastructure.

How Does the Cloud Work: Virtualization

Cloud storage is based on the principle of virtualization. Users can remotely access their data from anywhere, using any device with access to an Internet connection.

Virtualization divides a physical server into multiple virtual machines (VMs), each operating independently with its own applications and operating systems. This process optimizes resource utilization and reduces costs by allowing for rapid allocation and resizing of computing resources as needed.

Different Types of Cloud Computing

There are three main types of Cloud: public, private, and hybrid.

Each has specific advantages and characteristics, offering businesses different options to meet their needs for data management, security, and accessibility.

Public Cloud

Public Cloud services are provided by Cloud service providers, such as Amazon Web Services (AWS) and are hosted off-site.

This type of Cloud, available over the Internet, offers great flexibility. Ideal for fluctuating resource needs, it allows for quick implementation without significant upfront investments.

However, it may raise security concerns for sensitive data.

Private Cloud

As the name suggests, a Private Cloud is exclusively used by a single organization.
It can be managed internally or by a third party. It is therefore hosted either on the company’s premises or in an external data centre.

Offering increased control and enhanced levels of security, Private Cloud services are preferred for critical data and essential business applications.

Hybrid Cloud

The Hybrid Cloud model is a combination of Public and Private Clouds, integrating the best features of both types to offer a flexible and customizable solution.

Companies can manage their critical applications and data privately while taking advantage of the benefits of Cloud Computing, such as the scalability, while using the efficiency of the Public Cloud for other needs.

This model facilitates a balance between security, cost, and performance, making IT infrastructure more dynamic and adaptable to changes.

Cloud Service Models

Cloud Computing consists of three main service models: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service).

Each of these models offers different levels of abstraction and management, allowing businesses to choose the level of control they want over their cloud infrastructure, cloud platforms, and cloud applications.

IaaS (Infrastructure as a Service): for network architects and system administrators

IaaS provides virtualized computing infrastructure over the Internet.

With this model, businesses rent servers, storage, and networking, eliminating the need to invest in expensive physical equipment. Users manage their applications, data, middleware, and operating systems, while the provider handles the maintenance of the virtual infrastructure.

PaaS (Platform as a Service): for developers

PaaS is a Cloud service that provides developers with a platform and environment to build applications and services on the Internet.

Users create, test, deploy, and manage their applications using tools provided by the provider. PaaS includes infrastructure (as in IaaS) but also development tools, database management systems, and more.

SaaS (Software as a Service): for end users

SaaS allows users to access software applications over the Internet, usually on a subscription basis. The provider manages the infrastructure, platform, and software itself.

Designed for end users, this model is ideal for enterprise productivity applications, email, and collaboration tools

Advantages of opting for a Cloud infrastructure

Cloud Computing transforms businesses by offering a series of compelling advantages that directly address the challenges of the digital age.

From operational flexibility to economies of scale, to enhanced data security and business continuity, every aspect of Cloud Computing contributes to a more agile and robust IT ecosystem. Let’s explore the key advantages that make Cloud Computing a cornerstone of digital transformation.

Instant Access to Critical Data

With Cloud Computing, databases and applications are accessible at any time, from any device connected to the Internet. This facilitates real-time collaboration among teams, regardless of their geographical location.

Reduction of Initial Investments

Cloud Computing operates on a pay-as-you-go model, meaning there is no need to invest heavily in infrastructure and software. In the case of Public Clouds, it’s the service provider who owns and manages all the hardware necessary for the service to function. Companies can significantly reduce their capital expenditures.


Cloud technology allows for easy adjustment of resources based on current business needs. It’s possible to scale storage capacity up or down according to the company’s fluctuating business needs.

Enhanced data security

Cloud providers invest heavily in the most advanced security technologies and practices, thereupon offering data protection often superior to what companies could provide internally.
