Abigail is responsible for datacenters in a large, multinational company. She has to support multiple datacenters in diverse geographic regions. What would be the most effective way for her to manage these centers consistently across the enterprise?

The correct answer is to implement IaC. Infrastructure as code (IaC) is the process of managing and provisioning computer datacenters through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. Whether the datacenter(s) use physical machines or virtual machines, this is an effective way to manage the datacenters. Although datacenter 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 Abigail needed to configure and manage her network based on usage and performance. Finally, this issue is not just about provisioning; it is about management.
