Which type of data centre is commonly deployed for low-latency processing near users?

Edge data centres are small, decentralized facilities strategically placed closer to end-users and devices at the network's edge. Their primary purpose is to process data locally rather than sending it to a centralized cloud or enterprise data centre. This proximity significantly reduces latency, which is the time delay in data transmission. By minimizing the physical distance data must travel, edge data centres enable real-time applications such as IoT data processing, autonomous vehicles, and augmented reality, which are highly sensitive to delays. This architecture improves response times and saves network bandwidth.

A. Enterprise data centre: These are centralized facilities optimized for corporate needs, not specifically for low latency to a widely distributed user base.

C. Modular container: This describes a physical form factor (a prefabricated module), not a deployment strategy defined by location or latency reduction.

D. Legacy data centre: This term refers to older, often inefficient data centres, not a specific type designed for low-latency processing.
