I was playing with gcloud, particularly with deployment manager and have feeling that there are still many bugs in gcloud. DM seems like it has a good design and could be more powerful (especially ability to use templating and injecting Python code), but still feels buggy, error messages are very cryptic, and not feature full around updating (there is some rollback and preview functionality, but it is essentially useless). Nowhere close to what Cloud Formation is, even though from design it is less powerful. I was a bit skeptical why terraform is popular, doesn't feels like it brings anything new to CF, but could make a lot of sense to use instead of DM.
