The 6 essential criteria for choosing the right data center

Increasing your hosting space for your IT equipment, having high-performance connectivity with as many players in your digital ecosystem as possible, ensuring the backup of a main site, are among the reasons for using the services of a data center. If the choice of data center depends on the needs and objectives of the companies, it is above all a question of finding the installation which will best ensure the continuity of the activity.

Connectivity: a direct link with your partners

Evaluating the connectivity offered by a data center amounts to studying its community of members whose machines are installed on site, with the possibility of connecting directly to them. One of the criteria to consider is the variety of this community to offer all the direct connections expected – telecom operators, cloud, content, application providers, ISPs, content delivery networks, Internet peering points, freight forwarders, hosts… In which case it will be possible to connect to everyone, without going through intermediaries, or overcharging the costs. Even better: when a data center operator connects its facilities by direct and private link, its customers have access to the communities of all its sites and thus increases their connection possibilities tenfold.

SLA: the guarantee of service availability

Service availability is obviously the cornerstone of business continuity for data center customers. To guarantee it on all fronts, data centers deploy numerous physical and logical safeguards to avoid any interruption. Also, most have convincing availability rates, often over 99%.

To get an idea of ​​network availability and potential downtime, it all comes down to the decimal point: the higher the availability rate, the less downtime. Thus, a network that guarantees operation at 99.999% or 99.99% of the time does not quite provide the same service, because the authorized downtime can vary by a few minutes per year, but this can greatly impact operations. . Power supply: protect against unplanned service interruptions

The power supply of a data center must follow the growth of the hosted infrastructures. The ideal: an electrical configuration in N+1 as standard, with the possibility of doubling on request.

In addition, if the data centers provide emergency power solutions and electrical redundancy in the event of a breakdown, the backup time is not the same everywhere. Hence the interest of checking the electrical power (per square meter, per rack, etc.), the capacities of the backup units, or whether the dedicated rooms have their own power supply unit.

Respect for the environment: must have or nice to have?

For a long time, data centers have been working to reduce their energy consumption. Good practices include the use of renewable energies, the cooling of rooms by “free cooling” using outside air and less air conditioning, or by confining cold and hot air aisles to preserve the first and better evacuate the second. Signs of a state-of-the-art facility: ISO 14001 certification for environmental management. Better still, the datacenter can undertake environmental measures on other fronts, less expected, but signs of its commitment. This is the case for initiatives such as recycling rainwater for outdoor watering or reusing the heat released for heating public buildings.

Access control: ensuring the physical security of infrastructures

The control and protection of physical access are the essential link in any data center security policy. They concern the building itself, its perimeter and the servers it houses within its walls. These checks are based on technological devices (badges, biometric readers, video surveillance, etc.) and human presence (staff on site 24 hours a day, walkways, verification of the identity of visitors). The physical security of a data center also plans to cut short any disaster that could interrupt the activity – fire, water leak in priority. The more security a data center has, the more reliable it is.

Quality of service: beyond standard services

ISO 9001 is the certification to expect in terms of quality of service, coupled with ISO 27001 for information security. In addition, the “extras” offered alongside the basic IT hosting services are a good indicator of a datacenter’s quality of service.

The ideal would be to opt for a bundle of services that brings together in one place all that is necessary for the protection and archiving of the company’s computer data.
