Pick ONE OR MORE options

You notice that CPU usage is low in the instances, so you move the servers to C$5$ from MS because C instances are optimal for such workloads.

You notice that memory usage in Instances is low and CPU usage is also low, so you move the instances to R$5$ type Instances because they are suitable for such workloads.

You notice that the Instances are $"$on demand" and you find that spot instances are cheaper by $40\%,$ but you have to wait $2-3$ minutes more for them to come up$.$ So$,$ you decide to shift all of them to spot and overprovision the instances a bit, which will take care of the extra demand while the Instances come up$.$

You notice that CPU usage and memory usage are both low, so you decide to shift to an instance of smaller size but within M$5$ only.

None of these.
