A data centre is a purpose-built facility designed to house and manage critical data and IT infrastructure. Data centres house computer systems, networking equipment and storage systems, and provide a secure, controlled environment to protect critical data and applications.

Data centres use multiple layers of security to protect against unauthorized access, physical threats and data breaches. Security measures include multi-factor access controls, surveillance systems, firewalls, intrusion detection systems, security personnel and strict security protocols.

There are several types of data centres. Hyperscale data centres are huge facilities with vast data processing and storage needs. Edge data centres are smaller data centres located closer to end users to provide low-latency computing. An enterprise data centre facility is a data centre owned or leased by a single organization. An underground data centre is a facility located underground. Iron Mountain Data Centers has an underground data centre in Boyers, PA.

Every data centre has essential infrastructure components: robust power systems with backup generators for uninterrupted power, cooling systems to prevent equipment damage, and networking infrastructure for data transfer. Physical security measures such as cameras and multi-factor access controls are necessary to safeguard against unauthorized access and threats.
