What is cloud computing and what benefits does it bring to the business

Cloud computing consists in the on-demand distribution of IT resources via the Internet, with consumption-based pricing. Rather than buying, owning, and maintaining data centers and physical servers, you can access technology services, such as computing, storage, and databases, based on your needs by relying on a cloud provider.

Today, the Cloud is an ecosystem full of tools that can be interconnected in endless ways to create value for the enterprise. Artificial Intelligence Services, data analysis from devices that exploit the Internet of Things, creation of innovative startups: all around the so-called “cloud“, able to integrate and enable this increasingly sophisticated offer of technologies.

From a commercial point of view, Cloud Computing allows for the reduction of overall technology costs as the aggregation of different demand profiles on shared resources allows for achieving economies of scale as well as enabling the scalable and flexible delivery of services. Through this paradigm, Information Technology becomes a service purchased according to real business needs and paid according to actual consumption. In this way, the risk associated with IT projects is significantly reduced by moving from investment in fixed assets to current and variable operating expenses.

In recent years, Cloud Computing has become established in companies as a new and essential model of the use of ICT (Information & Communication Technology). The cloud allows you to access the updated and technologically advanced services of a service provider through the network, paying them directly for consumption. In this way, the internal management of IT becomes much easier and the time-to-market of digitalization is significantly reduced.

The importance and advantages of the Cloud are now known to most Italian companies that have made it an integral part of their IT strategy, considering it a preferential solution for the realization of new projects.


Types of Cloud Computing

There are different ways of deploying Cloud resources, called Public Cloud, Hybrid Cloud and Private Cloud.

Public cloud

With the Public Cloud, the resources provided belong to the provider, which makes virtual machines, storage, and applications available to companies and provides system management. With this mode, IT resources are shared by all users. The infrastructural investments are entirely supported by the supplier, while the customer pays for consumption only for the services effectively use.

Private cloud

A private cloud provides a pool of resources dedicated to the individual company that has exclusive access to the infrastructure system. This solution guarantees greater privacy as the network is not shared with other realities. The infrastructure remains dedicated exclusively to the user organization, which fully controls it. The Private Cloud can reside in the data center of the enterprise itself, remaining under the management of internal personnel, or can be entrusted to a specialized external provider, thus becoming a Managed Private Cloud.

Hybrid cloud

Hybrid clouds combine public and private clouds, united by technology that allows data and application sharing. A hybrid cloud provides more flexibility, and more deployment options, and helps optimize existing infrastructure, security, and compliance.


Cloud Computing services can also be classified according to their positioning concerning the architectural layers of the corporate information system. We identify in this sense three types of cloud separated, but from the border very labile: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software a Service).

Infrastructure as a Service (IaaS)

The provider offers the user computing resources to install and manage their applications. Infrastructure services or IaaS include networking resources, storage capacity, processing capacity, and the virtualization layer; these resources can be deployed in a scalable and flexible way according to the real needs of the business.

Platform as a Service (PaaS)

The provider offers the user, already pre-configured, platforms optimized for the development, testing, and delivery of custom applications. Tools typically included in a PaaS platform are operating systems, security systems, database management systems, application servers, integration services, business process management (BPM) tools, and software development environments. The customer controls and takes care of some aspects of the platform. At the same time, the underlying infrastructure is managed transparently by the service provider or the internal ICT management.

Software as a Service (Saas)

More and more companies are migrating to the cloud to do business. This is why it is important to have a clear strategy of how to do it safely, without exposing business processes to vulnerabilities. In fact, without upstream control of processes and data, you risk turning the cloud into a double-edged weapon that exposes even more vulnerabilities already present in companies.
