Each of which seems to be its own "hammer" for various problems. Yet each is also a kind of "factory" to make specialized "hammers," if you will.
ex: Seastar is a shared-nothing, highly distributed, highly async framework upon which folks have built a database (Scylla — disclosure, my employer), but also a streaming data platform (Redpanda), and a storage platform (Ceph's replacement, Crimson).
So maybe the one option the author left out is "a factory-building hammer."
