Thanks! If there's a public dataset that you're mirroring, maybe we should be hosting it for everyone under our public datasets program (feel free to ping me with your details).
Sadly, extended memory does not mean you can arbitrarily scale RAM versus cores for free. The memory above a certain ratio per vcpu is charged at a higher marginal rate. The focus of the product is for people that might only want more RAM, but if they add cpus something bad will happen (e.g., they don't have enough licenses for their software, or their code will literally crash). We'll try to update the docs to be clearer about this.
