Which term describes the ability of a cloud environment to add resources to service an increase in demand, thus allowing the system to effectively manage the additional workload?
The correct answer is 'Auto-scaling' because it refers to the process where the cloud environment can automatically adjust resource allocation based on the current demand, without manual intervention. This ensures that the system can handle increased workloads effectively. The other options, although related to cloud computing, do not accurately describe the automated process of adjusting resources to meet varying workloads.
