The course had a balanced structure with labs that helped supplement the learning material and it was incredibly beginner friendly.

Thank you for training on AWS development. Course was good and encouraging but labs need to be improved and provide more information and ask students to more work than provide solutions.

Instructor was engaging, very knowledgeable, and explained things clearly. Labs were helpful in getting used to the tools that were being taught. Course location (Atlanta Microtek facility) was very comfortably set up. I'd definitely recommend this to anyone learning a new skill. (I took the 3-day AWS Big Data training).

Awesome instructor with in-depth knowledge and the ability to present in a meaningful & understandable way. This course will provide a solid foundation within DataStage that can be used immediately. I highly recommend this course.

I just finished the 3 days training on AWS Solution Architect course instructed by Seid. He is very knowledgeable. He engaged the students and he is very friendly. The labs were well planned. I strongly suggest people to take the course.
