Thanks Anthony! Thanks Tom Haslett! I am so grateful that you have provided the course material for preparing for AWS Certified Solutions Architect. This was an excellent resource for me. It is well organized, well prepared, and makes understanding of AWS very accessible! In just two months of study I was able to take the exam (scored 90% - woo hoo!). Now, I'm planning to take the AWS Developer exam on 8/22/2017. I have great expectations. Thanks!
