I Have worked around with some SQL stuff with Azure along with working around doing random things with the instances you can use on there.
I personally have a lot of experience with oracle cloud as a online cloud hosting platform
While I was at I was working on a range of different small projects That Ranged from stetting up and deploying entire set of computers ready for people to be able to use.
I have done a fair amount of projects around VMWorkstation where I worked on my deployment skill and learned a lot about operating systems (like Windows server and ubuntu server) and so much more about the software.
