So that hackers don't waste time looking at Spanner:
The price starts at north of 300$ per month (https://cloud.google.com/spanner/pricing)
[edit] I'm apparently wrong.
This is still a masterclass in how not to do a pricing page IMO.

I have no idea why they chose to structure the pricing model this way, but it makes the entry-level cost look a lot worse than it really is.
In a PG or similar architecture, node might be used to specify how many "nodes" are in a replicated setup for high availability purposes.
In Spanner, "Node" is a measure of compute capacity (as is the finer-grain processing units) allowing you to scale up/down without impacting an application's workload.
All instances get high availability regardless of number of nodes or processing units, and the specifics of this are handled by the configuration.
