Data center engineering includes basic environmental construction projects such as computer room decoration, computer room power distribution, precision air conditioning, computer room UPS, lightning protection grounding, etc

The core concept of virtualization and cloud is to create usable environments from abstract resources, so it is easy to confuse them. Virtualization is a technology that allows users to create multiple simulated environments or dedicated resources based on a single physical hardware system. Cloud is an IT environment that can abstract, aggregate, and share scalable resources across the entire network. In short, virtualization is a technology, while cloud is an environment.

Data communication is a new form of communication that combines communication technology and computer technology. The transmission channel connects data terminals with computers, enabling the sharing of software, hardware, and information resources among data terminals in different locations.

Hyper converged infrastructure (HCI) combines general-purpose data center hardware and intelligent software that use locally connected storage resources to create flexible building blocks, replacing traditional infrastructure consisting of individual servers, storage networks, and storage arrays. Its advantages lie in reducing total cost of ownership, improving performance, and enhancing the efficiency of the IT team.
