"I hear and I forget. I see and I remember. I do and I understand."
I always like to do more hands on practices which help me remember and understand better. Below has many good and easy to follow workshops for many AWS and partner services:
1/ https://workshops.aws/ (100 workshops and growing)
2/ https://awsworkshop.io/ (many partners here)
3/ https://awesome-aws-workshops.com/ (Unofficial Curated list of awesome workshops found around in the internet.)
Just remember to do the last CLEAN UP step to delete those resources you do not need AFTER the workshops. I did a workshop a few months ago with Sysdig and EKS but forgot to delete IGW (which was to ship the EKS metrics, data to Sysdig monitoring), so a few more dollars till my billing budget alerts showed up.
