I’ve been using Habitat (by Chef) since its initial release. That makes it approximately 2 years. I’ve been using it more seriously in the past year, after a visit from Habitat engineers, and opportunities to engage with it in my regular work. Additionally I’ve been able to sink a bit of personal time into it. But what is it? Habitat is 3 primary things to me: Portable application builds! Networked, cluster-aware process supervisor Release / deployment management These are all HUGE for any application developer.
