I passed the AWS Certified DevOps Engineer - Professional after about one month of study, so here’s a brief note.

Preparation Method

• Exam Guide
• BlackBelt materials for important services
• Official free practice e-learning
  • Exam Readiness: AWS Certified DevOps Engineer - Professional
• Hands-on practice (especially CF and Code series)
• Official practice exam
• Paid question bank (Whizlabs)
• Whitepapers
  • Practicing Continuous Integration and Continuous Delivery on AWS

Study Subjects

Having studied broadly for the Solutions Architect Professional and various Specialty certifications, I focused on hands-on practice and study of key services. I was able to progress smoothly in part because I had already obtained SAP and others.

Important Services

• Systems Manager
• CloudFormation
• Elastic Beanstalk
• Config
• CodePipeline/CodeBuild/CodeDeploy
• CloudWatch (especially Logs, Events, etc.)
• AutoScaling
• ECS

Required Concepts

• CI/CD
• Disaster recovery design
• Deployment (Blue/Green, Canary releases, etc.)
  • This is a good reference:
    • AWS Black Belt Online Seminar: Deployment on AWS
• RTO/RPO concepts
  • Whether you can choose the appropriate backup and design for each use case
• Backup/Recovery

Services Worth Studying at a High Level

• Inspector
• EC2
• Opsworks
• StepFunction
• GuardDuty
• Macie
• KMS
• DynamoDB

Impressions and Other Notes

I feel like I’ve gained the concepts needed for DevOps starting with CI/CD, knowledge and skills needed for operations. During the exam, I felt that many of the scenarios closely resembled situations I had considered in my actual work, and it seemed applicable to my day-to-day job.

Passing this, I now have 11 certifications. With this many, 12 certifications is the final goal, but I plan to study for the G Certification for deepening ML knowledge and IPA exams in winter and spring.
