Initial considerations

🔍 Evaluate possible institutional options.

• Consult with your local IT group about whether an institutionally managed system would meet your needs. These systems are managed by technical experts at the University, divisional, or departmental level, allowing you to focus more on the task at hand, rather than maintaining the security of unmanaged systems.
