Bazel is part of the story of how Google manages provenance for build artifacts (https://cloud.google.com/security/binary-authorization-for-b...)

This is not entirely correct. It's not Bazel but "build system very similar to Bazel" (from your source) and that's I guess their internal Blaze tool.

I wonder what's the real usage of Bazel (not Blaze) in Google.

According to this comment [0] by laurentlb (one of the people working on Bazel who also commented in this post) from a year ago, Blaze is just Bazel but with integrations to Google-internal tools.
