The most expensive server costs over $250 per hour. It comes with 448 vCPUs and 24TB RAM.
Most regions have 3 independent zones.
Some are single-zone, and one have 6 zones.
While spot prices are relatively stable nowadays, they can still fluctuate by up to 10% within a day.
There is a 2500x performance difference between the fastest and slowest nodes.
Some vendors charge 6+ times the price of a public IPv4 address compared to others.
