Data centers are centralized locations that organizations or companies use to house their applications and data. It is designed on a network of computing and resources that enable the delivery of shared applications and data. Due to the growth in big data and cloud computing, data centers have evolved from stacks of servers that are placed in a room. It is calculated that there are more than millions of data centers all around the world. Big companies like amazon, google, Microsoft, etc. have more than 50 data centers with more than a million servers. These data centers have other resources as well such as Power supply, Air conditioner, batteries, etc. AR assistance can be done to help solve unknown problems. They can be used to put experts from around the world for support. They can help on-site workers with the help of AR devices and see a real-time view of the data center and suggest the right actions needed to fix the problem.
Augmented Reality (AR) is a technology that reacts to real-time changes shown by a person.  AR applications help make virtual objects and allow them to move the objects. In data centers, augmented reality will give the users the capability to better interact with the environment, having contextual information always at hand and allowing the mechanics to execute maintenance work at a faster speed, lower costs, and unaltered quality. AR can be used to execute complex work, like cabling, stacking, etc. A mixed-reality application will show the engineers through mounting and installation, offer visual improvements through holograms such as cabling sequences and mounting positions, and keep the design and layout information near the engineer at all times.
