A Tier III data center provides 99.98% availability. With this configuration, it is possible to provide maintenance without affecting the continuity of service provision on the servers. However, these data centers are not protected from outages in the event of serious accidents on the various components of the infrastructure. In other words, Tier III data centers do not have overall modular redundancy.
This is the highest Tier of guarantee that a data center can provide with 99.99% availability. This category of data centers is fully reserved for electrical circuits, cooling, and network. This architecture can withstand even the most serious technical failures on the server without any consequences for the availability of the system.
