Personally, I farm to work out to the cloud.

I simply purchase whatever I need, have it delivered to an Amazon locker nearby, and then when I’m done with it I throw it out and order a new one.

The most frequently used ones are always at the locker and the least frequently used one is automatically returned for a refund. The cache miss is approximately two days.

It’s expensive, but you can’t beat the fact that it scales to a practically unlimited degree.

I call it “bowl-less” caching.
