What you’ll learn

  1. Building and powerDescribe power redundancy, PUE, and airflow layout.Data centres engineer power paths and aisle airflow to keep racks running efficiently.
  2. Compute and networkExplain racks, virtualization, latency, and interconnection.Physical racks host virtual workloads; placement trades cost against round-trip time.
  3. Cooling, security, and opsCover cooling, physical security, maintenance, and region choice.Heat rejection and access control protect uptime; regions define failure domains.

Questions this course answers

What does PUE measure?

PUE compares overhead energy to IT load; lower usually means less waste heat and losses.

Why do providers offer edge locations?

Distance and routing hops add delay; edge sites shorten paths for latency-sensitive workloads.

What happens if cooling fails in a dense hall?

Without heat removal, chip temperatures rise until protective shutdown.

What is the cold aisle for?

Cold/hot aisle layouts separate intake and exhaust airflow in rack rows.
