IT side of GIS

I have been a GIS Analyst/Specialist for the past 18 + years. I feel when it comes to ESRI/Pro I can “figure it out.” However, after over the years I have realized I could use more seasoning on the IT side of GIS.

I am particularly intersted in learning SQL, improving my knowledge of programming, Microsoft Server, etc. Does anyone have any reccommendations on coursework I could complete to help aid in this effort?
