Distributed Systems Training Courses

I have a lot of time on my hands in the next couple of months and I want to spend some of it learning. Can you folks recommend courses for distributed computing that i can take whether online or in person here in SF/bay area? If it has to be taken during business hours for a week i dont have issues with that, and if it’s a little pricey i don’t mind paying the difference on what our training budget will allow. No trolls please. TC 275k
