Whoops. I accidentally wiped the VM running my Wordpress blog.
I'm not a fan of microservice architectures like Jamstack as it tends to add complexity, cost and a dependency on potentially unreliable 3rd-parties.
That said, I don't need much functionality on my blog. This is JAMstack with very little J and no A. I may add comments at some point, but only if I can self-host them.
The founding developer of Wordpress, Matt Mullenweg, has this to say about it:
JAMstack is a regression for the vast majority of the people adopting it
Matt is biased, of course, but I agree with his arguments. Read them in more detail at thenewstack.io.
