My experience of TF is very much the opposite. It looks fantastic on paper (well, in the browser) and I was excited to start using it. But the shine quickly wore off. It claims to be multi-cloud but it's not as if you can take some TF from AWS and run it on Azure - it's a rewrite. And it claims to be able to import existing, running cloud configurations so migrating to it should be easy, but it doesn't work, so that's a rewrite. And it is terrible at modifying existing things, the developers of TF seem to be believe that destroying everything and rebuilding from scratch is the way to, say, add another node. Of course by the time you figure all this out you have invested so much political capital in persuading the organisation and your peers to adopt it that you're stuck with it. But the lesson is really, use whatever is native to each cloud, such as CF on AWS, beyond any trivial deployment you're locked in anyway, might as well enjoy it.
