1. Keep in mind "potential savings" is different from "actual savings".
If the EC2 hosts have already been reserved then Netflix "cloud costs" would be relatively stable. What you might see is a reduced rate of increase y/y.
2. Keep in mind Amdhal's Law (or rather a slight variant). The absolute reduction has to be weighted against the percentage of resource usage that has been reduced.
(All numbers are made up) If previously Netflix was paying 3MM for encoding, and now they are paying 0MM; Compared to an annual 30MM on streaming with a ~25% y/y growth, you wouldn't notice the missing 3MM unless it was pointed out.
