👉 Ghost computing refers to the practice of using computing resources, such as servers, virtual machines, or cloud instances, without them being directly utilized by end-users or applications. These resources are often idle or underutilized, yet they remain available for potential future use, typically to optimize costs or handle unexpected demand spikes. In essence, ghost computing involves allocating unused computing power to a network of idle machines, which can then be brought online as needed, effectively "computing ghostly" when no active tasks require their services. This approach is particularly common in cloud computing environments, where providers can dynamically allocate resources based on demand, ensuring efficient use of infrastructure while minimizing waste.
