I was going to mention CloudRun as a specific counterpoint to the author's opinion on serverless functions. It can't get much more portable than a container running on arbitrary HTTP triggers. We use pub/sub as a trigger because we like the functionality but you can do whatever you want. You can, for example, containerize your monolith and expose task triggers via API endpoints so your web server doesn't have to do that work. I really like it.
