The Deploy Tab is a control panel for your Processes. You can define the Atoms where processes will run and identify the required process versions. Once you have built and tested a Process using Test Mode, you will need to deploy it to an Atom to run in "production". Deployed processes do not have any of the data volume limitations of Test Mode and can execute automatically according to their configured schedules. Connections contained within deployed processes do count towards your AtomSphere subscription.
Deploying a process creates a new deployment version of that process, which enables you to perform change management of your integrations. You can configure and test (using Test Mode) changes and enhancements to your processes without affecting the versions running in production. When you're satisfied with the changes, you simply deploy a new version of the process and it will update the configuration running in your Atom.
You can also "roll back" deployments. Because every deployment version is tracked, you can re-deploy a previous version if you ever needed to roll back a change that was made. For example, if you deployed an enhancement that broke the process, you could quickly re-deploy the previous version to get it running again while you troubleshoot the problem using Test Mode.
