I've never used any of Hashicorps stuff (thought consul did arrive on my radar theother day..). Any recommendations? We use the Atlassian stack here (stash, bamboo, etc) and deploy to AWS (regular AMIs rather than any of that fancy docker stuff). Anything here we should look into?
I don't really use anything of Hashicorp's except for Vagrant. That his been fairly revolutionary for all of the teams I've brought it to. That is, Vagrant + Ansible. A repository of Ansible configuration scripts that can easily be slurped down to provision a Vagrant image means much more portable development environments.
In the case of the company I'm currently at it's even more important because we have a firmware build system with a non-trivial configuration that would take days to replicate correctly (because of all the "missing pieces" required that the original developer forgot to write down when documenting the process post-setting it up).
Packer is great for generating AMIs, particularly if you're already using some form of config mgmt. It will let you tie in your existing puppet/chef/salt/ansible/shell/etc. and output amis based on your config.
