• Targeting is easy and yet extremely granular - I can target machines by name, role, operating system, init system, distro, regex, or any combination of the above.
• Abstraction of OS, package manager and package details is far advanced beyond any other CRM I have seen. The ability to set one configuration for a package across multiple distros, and have it apply correctly no matter the distrospecific naming convention or package installation procedure, is amazing.
• Abstraction of environments is similarly valuable - I can set a firewall rule to allow ssh from "management", and have that be defined as a specific IP range per dev, test, and prod.

• The GUI: The GUI interface for Consul has gotten a lot better over the years. Since Consul is so easy to interact with via API, this isn't a showstopper, but for those that are less command line inclined it's always nice to be able to refer them to an easy to use and understand web interface
• It's chatty: Consul is extremely chatty. Sometimes it's particularly chatty at 2am with no indication as to why and eats up quite a bit of resources. Just be sure to provision your systems that typically take a heavy load with a little extra for Consul

• Managing network hardware should be more native and easy
• SaltStack should buffer jobs and, when a client returns, make sure it is executed proberly
• SaltStack should provide basic pillar and states structures to help get newbies started

• It contains a native web UI, which in contrast to its counterparts, is handy, very intuitive and - most importantly - very informative. It leaves no room for doubt about your services "forest" health. So, for that purpose, the learning curve was almost down to non-existent. Our team managed to work seamlessly with Consul being our services API
• Our management staff had a difficult time understanding what Consul was really all about. For technical staff it is pretty simple to understand the huge value such a tool can pose to our suite of solutions, but once our management staff took the grasp of its valuable handy set of tools, we didn't take long to start using it and keeping track of our Swarm overall health, with was a constant concern for the entire company before.
• For load balancing purposes, we were relying pretty much on guesses before we decided to use Consul. One would check a certain node overall health and decide if we would need to spring a new instance at AWS or Digital Ocean.

• We manage two complex highly available self-healing (all infrastructure and systems) environments using SaltStack. Only one person is needed to run SaltStack. That is a HUGE return on investment.
• Building tooling on top of SaltStack has allowed us to share administrative abilities by role - e.g. employee X can deploy software Y. No need to call a sysadmin and etc.
• Recovery from problems, or time to stand-up new systems is now counted in minutes (usually under eight) rather than hours. This is a strategic advantage for rolling out new services.
