At one point, I was considering paying out of pocket to attend the course. Fortunately, the company I was working for at the time wanted to send people to it and I got selected.
After taking the course, even if I did have to pay myself, I wouldn't have been upset.
Not a super big impact professionally. Creating and maintaining distributed systems is hard. And even harder when business requirements, stakeholders, etc. get involved.
One major take away I got from the course is to limit the more RPC-driven services I typically saw up to that point (and still see in current microservices examples to this day).
He also gave a lecture on the different types of coupling, which I had never even heard of prior to the course.
He also has a few talks on YouTube as well as others that work at Particular Software. I'd highly recommend checking out all of them.
Around April/May, they ran this course for free for 60 days. I progressed to few lessons, but had to stop as I had to focus on some critical stuff at work. I can tell it was good as far I went. I wish I convince my company next year to put us through this course.

That course is outstanding.
