Content Outline

• Module1

  Design Resilient Architectures (30%)

  • single AZ : not for scalability, availability
  • managing service : for redundancy, availability in region
  • 내결함성 : 성능상의 요구조건을 충족시키지 못한 것
    • ex. 어떤 서비스가 반드시 성능을 만족시키기 위해 4대가 동작해야함. 하지만 2개의 AZ에 instance가 2개씩 있음. 1개의 AZ가 다운 되더라도 나머지 AZ는 돌아감. -> 내구성 O
    • 고가용성 O, but 내결함성은 X (결함 발생한 거라서)
      • 가용성 : 시스템의 내구성을 측정하는 방법
  • ex. 2 AZ에 각각 4개의 instance가 있음. -> 고가용성 O, 내결함성 O
  • 모든 구성요소에서 장애가 발생할 수 있음
    • 자동으로 복구되거나
    • multi machine이 동작할 수 있도록 분산해서 처리하도록 설계하는 것이 중요

• Module2

  Define Performant Architectures (28%)

• Module3

  Specify Secure Applications and Architectures (24%)

• Module4

  Design Cost-Optimized Architectures (18%)

Dump

I studied examtopic dump(574 questions) twice and tried to analyze and remember some keywords on each question. Some questions have the specific pattern like having same keywords. But I heard there are not similar questions on the real test. I felt I need to study and get used to many kinds of situation of efficient AWS solutions. And When I take a test, I exactly felt it and I did good study.

For studying AWS SAA, I could know and understand flow of AWS and how to use many AWS solutions easily and efficiently. I totally can sure that AWS SAA will help our backend development skill improve.
