You need to deploy a new service to production. The service needs to automatically scale using a Managed Instance Group (MIG) and should be deployed over multiple regions. The service needs a large number of resources for each instance and you need to plan for capacity. What should you do?

A. Use the n1-highcpu-96 machine type in the configuration of the MIG. B. Monitor results of Stackdriver Trace to determine the required amount of resources. C. Validate that the resource requirements are within the available quota limits of each region. D. Deploy the service in one region and use a global load balancer to route traffic to this region.
