I'm assuming you aren't aware of FoundationDB: https://www.foundationdb.org/files/fdb-paper.pdf

Having that context puts the post in a much better perspective. It's definitely an introduction post (the company has been developing this in stealth mode for the past few years), but it is most certainly _not_ a marketing post. These people developed extremely novel testing techniques for FoundationDB and are now generalizing them to work with any containerized application.

It's a big deal.
