OnApp virtual server templates are pre-configured operating system environments that deploy in a couple of clicks.
With the full version of OnApp Cloud you get a set of base templates for your installation, and free access to a huge library of Windows, Linux and FreeBSD templates. You can also get access to the JumpBox library of Open Source web applications for a discounted monthly fee.
All templates work with Xen and KVM hypervisors unless noted.
For the list of OnApp templates, refer to http://templates.repo.onapp.com/
