Hmm, this is the second such post I've seen recently that lays out the company's infrastructure stack and after a few points, it mentions how they've outsourced all their logging and alerting to DataDog who solved all their problems in that area. DataDog seems like a nice product, and I know nothing about it, but after seeing how ... aggressively they were marketing at re:Invent, color me skeptical that these stack discussions are entirely spontaneous.
