What Is The Private Cloud?


Cloud computing opens new horizons for companies, facilitating the development of new services or making more advanced technologies and infrastructures more accessible.

But this technology is still scary, especially on data security in the “cloud”. The news does not help to restore confidence: cyber attacks, security flaws, data leaks, all this (often mistaken) the image of the Cloud.

In return, companies are becoming more aware of the weight of their data and the importance of protecting them.

To take advantage of the benefits offered by the cloud while ensuring the security and the sovereignty of the data, the best solution is found.

The private cloud, a total control of the infrastructure

The company invests in its own infrastructure and makes it available for self-service to its employees.

A tailor-made installation

The company, therefore, masters the infrastructure from A to Z: from the choice of hardware (CPU, storage, licenses, bays, etc.) to the creation of virtual servers through the layout of the server room ( power and air conditioning).

Full control of the data

The infrastructure is the exclusive property of the company, it is not shared as it is the case of a public cloud.

The company can also implement the security measures of its choice: antivirus, security gateways, VPN, anti-DDOS, etc.

The limits of the private cloud

This is not a quick fix and is therefore not fault-free, the most important being the high cost of investing in a complete IT infrastructure.

A significant investment

Between the hardware costs (servers and components/storage arrays/licenses), installation and configuration, not to mention the labor costs for maintenance, the investment represents a significant budget.

To this initial investment, we must add the “hidden” costs of maintenance of equipment, administration, and regular updates, but also the regular renewal of equipment.

Specific skills needed

The administration is very time-consuming: between energy maintenance, air conditioning, updating software and operating systems, deployment and configuration of cybersecurity solutions, all this takes time!

Evolutions are expensive

The company today must demonstrate great agility and its IT infrastructure must follow.

Whether it’s launching a new product, opening a production site or recruiting employees: IT resources are needed.

However, a 100% on-site infrastructure does not offer this agility because it is not very scalable: hardware limitations frequently require new investments.

Similarly, the company can quickly face the lack of space: a server room requires space and specific amenities (especially in terms of air conditioning and power).

One solution: the hosted private cloud

Faced with the constraints of a private cloud on site, hosting is a solution that has many advantages.

We talk about a hosted (or external) cloud when the infrastructure used to build it is hosted by a provider.

Hosted infrastructure offers the same benefits as the on-premise infrastructure without the hassle.

Limit investments

Infrastructure as a Service (IaaS) provider provides the company with an on-demand data center and infrastructure resource.

This service is usually billed on a monthly basis and has the advantage of not investing in the infrastructure, which is available immediately.

The company moves from Capex to Opex, which facilitates accounting.

Relieve internal IT teams

Part of the maintenance (including material) is taken care of by the supplier, who is engaged with a specific contract and SLA (Service-level Agreement).

The internal IT department can, therefore, devote itself to projects with the higher added value around the IS.

100% scalable infrastructure

The data center is maintained and updated by the supplier, who is responsible for changing the fleet according to the latest technologies and standards.

Unlike an on-premises infrastructure, resources are calibrated to exactly match the needs of the business.

In addition, they are 100% scalable: it is possible to add resources on the fly, whether storage space, computing power or other.

A private cloud is a suitable option for companies who want to benefit from certain advantages while controlling the infrastructure and their budget.
