Need some advice. I recently received a bad grade on my literature review assignment. The next assignment deals with research methods and methodology to answer my research questions. Need some advice on how to proceed. These are the questions I am trying to answer. If anyone could provide guidance on how to narrow the scope of the questions or recommendations on research methods and methodology, it would be greatly appreciated.

In regard to Terraform, Ansible, Chef, and Puppet IaC tools,

How does the execution speed of each tool compare in cloud$-$native and hybrid cloud environments, more specifically for multi$-$cloud setups?

How well does each tool detect and prevent common security risks in configuration scripts?

How effectively does each tool handle failures in large and multi$-$cloud deployments?

How well does each tool integrate with security tools and manage configurations securely in large$/$multi$-$cloud environments?

What is the cost difference for each tool, based on the environment, to be implemented?
