What is a Tier 4 data center?

The concept of a Tier 4 data center refers to the Uptime Institute’s classification, which evaluates the level of redundancy and resilience of the infrastructure. A Tier 4 data center is the highest level:

• 99.995% availability: Less than 26 minutes of downtime per year.
• Full redundancy: Each critical component (power supply, cooling, network) is duplicated to avoid any single point of failure.
• Fault tolerance: Even if a piece of equipment fails, the data center continues to operate without interruption.

Why choose a quality and secure data center?

Unparalleled availability

A quality data center ensures the continuity of your services, whether it is an e-commerce site, business applications or VoIP communication systems.

• Disaster recovery plan: In the event of a major incident, redundant failover mechanisms guarantee almost instantaneous restart.

Advanced security

• Highly controlled access: CCTV cameras, biometric airlocks, regular patrols.
• Fire and intrusion protection: Early detection systems, automatic extinguishers and rapid intervention procedures.
• 24/7 monitoring: A secure data center must prevent any attack or failure through proactive monitoring.

Regulatory compliance

• Multiple certifications: Tier 4 data centers often obtain approvals (ISO 27001, HADS, PCI-DSS) as a guarantee of reliability.
• Data protection: Storing your data in an environment that meets international standards makes it easier to comply with legal obligations (GDPR).

How to recognize a Tier 4 data center?

• Dual power supply: At least two independent sources to compensate for any outage.
• N+1 redundancy: An additional component is always available in the event of a breakdown.
• Uninterrupted maintenance: Maintenance operations are carried out without impacting your services.
• Performance index: The availability rate is guaranteed by strict SLAs.
