Just finished a three day virtual class on "Data Warehousing in AWS" offered by ExitCertified. The course content and instructor (Chris Littlefield) were top notch. I learned more than I expected to in the time spent. I appreciate that we get 90 days in which to continue to access the lab environment to repeat/review the course labs, as well as 2 years' access to the course e-book which provides pretty much the entire slide presentation, a valuable appendix and links to other content. Highly recommend this class for anyone needing the ability to analyze massive amounts of data in AWS.
