Cheryl is responsible for data centers in a large, multinational organization. She has to support multiple data centers in diverse geographic regions. Which of the following is the MOST effective method for her to manage these centers consistently across the enterprise?

Infrastructure as code (IaC) is the process of managing and provisioning computer data centers through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. Whether the data center(s) use physical machines or virtual machines, this is an effective way to manage the data centers. Although data center managers may be needed, that won’t necessarily provide consistent management across the enterprise. Software-defined networking (SDN) will not fix this problem, but it would help if she needed to configure and manage her network based on usage and performance. Finally, this issue is not just about provisioning; it is about management.
