Hi everyone. I am founder of Codenvy. We are introducing pay-as-you-go metering and pricing construct. This effectively unlocks all limits in the system and lets users create as many projects, workspaces, and machines as they'd like. IDE time is free. We count time used for machines to perform builds and runs, and then measure that consumption for billable elements. All users have a free monthly allotment, and then a credit card can be added for any other consumption. Pre-paid bulk purchases can also be made. All users optionally have always-on machines if they'd like, or to use machines that are only active for the duration of a build / run event. We hope the community provides feedback on the new system and gets value out of it.

We use Codenvy for TeachingKidsProgramming for this reason. Plus they have excellent support for Java IDE features.

Cloud == Elasticity + Multi tenancy + Meter based pricing ==> Codenvy == The Cloud Development Environment !
