Mind-blown moment 🤯
Both pods block an entire node, but cost differently.
It's time for better cost tools and models!

Plot twist: AWS uses a 90/10 split!

90% of cost based on CPU
10% of cost based on memory

Let's calculate... 🧮
4/6 Pod A (CPU beast):
90% * (2/2 CPU) + 10% * (0.1/8 GB) = 0.90 or $63/month
5/6 Pod B (Memory monster):
90% * (0.5/2 CPU) + 10% * (8/8 GB) = 0.325 or $23/month

First insight: Each pod blocks a whole node! 🤔
Pod A maxes CPU (2/2)
Pod B maxes memory (8/8)
So they should both cost $70/month... right?
