- Software versions no longer force faculty to follow IT staff schedule.

- School and Student/family-owned consumer technologies can be leveraged
- desireable to operate in a
- IT has increased flexibility to tailor/customize software
provisioning for teaching/learning

- In Scaling Up STEM Learning With the VCL, the Cloud delivered such
software as Geometer's Sketch Pad and Fathom (dynamic data software.)

- try out - be in charge
- when is it a bad idea to be root?
- provision accounts
- set permissions
- other configure the system tasks
- install and use software
- web server (e.g. Apache)
- RDBMS (e.g. MySQL)
