The Cost of Multiple Platforms
I ran into an interesting post that noted the modern data platform can have a bunch of different systems underlying it. The example might be that your "software" could use PostgreSQL, MongoDB, Cassandra, Clickhouse, and something NewSQL (Spanner, CockroachDB, etc,). Some of you might think that's not reality, but keep in mind that for a lot of your organizations, the "software" is what the customer uses.
