How should you run this reverse proxy?
A . Create a Cloud Memorystore for Redis instance with 32-GB capacity.
B . Run it on Compute Engine, and choose a custom instance type with 6 vCPUs and 32 GB of memory.
C . Package it in a container image, and run it on Kubernetes Engine, using n1-standard-32 instances as nodes.
D . Run it on Compute Engine, choose the instance type n1-standard-1, and add an SSD persistent disk of 32 GB.
