What can Jeff implement to automatically scale CPU capacity in his private cloud?

Implementing autoscaling in Jeff's private cloud allows the system to automatically adjust the amount of CPU capacity based on current workload demands. Autoscaling helps ensure that there is enough computational power during peak usage times and conserves resources during low usage periods. This dynamic adjustment promotes cost efficiency and optimizes performance.

While Puppet and Chef are both configuration management tools that can assist in managing resources and deployment processes, they do not inherently provide the functionality to scale resources automatically based on demand. Docker, on the other hand, serves as a containerization platform that facilitates the deployment of applications but does not directly manage resource scaling like autoscaling can. Thus, autoscaling stands out as the most direct and effective method for dynamically adjusting CPU capacity in response to workload changes in a cloud environment.
