What's really got me excited lately is the combination of Ansible (for dirty work) and container orchestration systems like Kubernetes/Rancher/etc (also, tools that go from one orchestrated host to many like dokku and flynn).
While I appreciate the competition from GCE and Azure, what I really want is a tool that will run in any one of their clouds, but offers the same ease-of-management, and lets me go from one cloud to another or to a private cloud without breaking a sweat. I want the competition to be 70% on price and 20% on added-management-value and 10% on bundled services.
Terraform is basically this tool, but I want an even easier interface, terraform still feels somewhat too specific to me -- I don't want to even have to write config or specify some "aws" adapter that will make my config work on some provider. I want instant, multi-cloud (possibly) heroku, using only the network, hard-drive-space, ram, and lxc "primitives".
Someone (maybe me if I ever find time) just needs to get to work making F/OSS versions of all the bundled tech (ex. blob storage, cloud function runners, dynamically configurable DNS resolvers, simple alerting, etc) that runs in a container, and then the question just becomes "where can I get the cheapest most performant VPS that will host my containers".
