I am wondering what is the difference between the cost of a powerful 3-nodes cluster (let's say, 320gb of RAM, tons of CPUs), vs a 30-nodes cluster but each node as 2gb RAM and 2 CPUs.
It seems that the 3-nodes cluster will be around 15k and the 30-nodes cluster 150k (unless I can negotiate a good deal).
This doesn't make decentralization cost-effective at all. This encourages having a 3-nodes cluster and simply on-boarding clients to it, increasing the RAM and CPU as needed. Am I right?
