VM Sprawl
VM Sprawl refers to a common challenge in companies where virtual machines (think of them as digital computers running inside actual computers) multiply without proper control. It's like having too many unused apps on your phone taking up space. When candidates mention managing VM sprawl, they're talking about their experience in keeping these virtual environments organized, cost-efficient, and well-managed. This is important because uncontrolled growth of virtual machines can waste company resources and increase IT costs unnecessarily.
