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
