AWS Certified Solutions Architect — Associate

Preparation for SAA-C03, taught through architecture rather than flashcards.

What you'll be able to do

  • Choose the right service for a scenario and justify the choice
  • Design for availability, durability and cost at the same time
  • Read a question and spot which constraint is actually being tested
  • Build the reference architectures, not just describe them
