Data center houses critical computing resources such as server racks, routers, switches, redundant power sources, and firewalls. A data center infrastructure covers all of the physical or hardware-based components, including servers, computers, networking equipment, such as routers or switches, security, and storage equipment, and data center management software, as well as non-computing resources.
Data center design should cover IT resources, architectural layout, and infrastructure. There are some standards for data center infrastructure. Data center tiers are used for explaining specific kinds of data center depending on specific features. Tier certification proves some features of a data center such as respect, guidance, risk avoidance, higher efficiency.
