Environments are now free!
As many of our clients have pointed out, it doesn't make sense to charge for additional environments, especially when Scalr asks you to choose a plan based on a number of managed instances. Therefore, all environments are free—effective immediately. Have at it!
Scalr environments are now free
For those that need a refresher, an environment is a set of cloud infrastructure keys used together to create farms. For example, if your production environment contains some Rackspace and some AWS keys, then you can create a farm that includes instances from both providers: if one goes offline, your traffic goes to the remaining one.
Multiple environments allow you to isolate farms entirely. This can be useful to make sure your Dev environment doesn't screw up your Production one. You can even set up an environment for each one of your clients so that billing, farms, and access are all separate.
