Preparing for AWS Certified Developer Beta Exam Presentation Transcript

  • 1. Preparing for AWS Certified Developer Beta Exam Bhavesh Goswami CloudThat Technologies
  • 2. AWS Certified Developer Beta Exam • Amazon has now released Beta for “AWS Certified Developer” and “AWS Certified SysOps” at Associate level. • Until now only the “AWS Certified Solutions Architect” was available at the Associate Level. • The “AWS Certified Developer certification at Associate Level” is now available through Kryterion testing centers. • The cost of the certification is $75 (compared to the $150 price for the Solutions Architect, possibly because its beta). • The beta certification has twice the number of questions and even the results are not provided immediately. But AWS says that the results will be provided in 8-10 weeks post the beta start date. • Also, if you fail the beta exam, you get a free voucher to give the exam again when it comes out of beta.
  • 3. Current and Future Certifications in the Pipeline Source: http://aws.amazon.com/certification/
  • 4. AWS Certified Solutions Architect vs. AWS Certified Developer Beta exams
  • 5. Topics for AWS Certified Developer Associate Level Exam 1. 2. 3. 4. AWS Fundamentals (10%) Designing and Developing (40%) Deployment and Security (30%) Debugging (20%)
  • 6. AWS Fundamentals (10%) This section tests basic knowledge about AWS. AWS blueprint says that the following services are part of the certification: • Core AWS Services (S3, IAM, RDS, EC2, ELB, EBS, VPC, etc.) • DynamoDB • Simple Queue Service (SQS) • Simple Notification Service (SNS) • Simple Workflow Service (SWS) • AWS Elastic Beanstalk • AWS CloudFormation
  • 7. Designing and Developing (40%) This is the section with highest weightage at 40%. You will be required to know the general architecture and use cases for all the AWS services mentioned in the previous slide. There can be questions on feasibility of using a particular service for a particular use case, or which service (or group of services) will be best suited for a given use case. Another consideration is how to most efficiently use a service. Some types of questions might be: • Given a dataset what will be the best indexing strategy for DynamoDB for a given use case. • The best strategy for designing S3 key space and ACLs given a particular type of dataset and use case. • Consistency model of each of these services. For example, S3 is eventually consistent while DynamoDB has a consistent read option.
  • 8. Designing and Developing (40%) contd.. • Various limitations of the Services. For example, in S3 how many buckets can you create for an account, in Dynamo how many indices can you create, size limitations on hashpartitions, etc. • Most popular S3 APIs are GetObject, ListBucket, PutObject, etc. and for SQS it is CreateQueue, SendMessage, DeleteMessage, etc. • AWS SDKs available for different programming languages
  • 9. Deployment and Security (30%) This section will have questions on various ways infrastructure on AWS can be secured. There could be multiple ways infrastructure can be secured and knowledge of these methods is necessary. For example, VPC public & private subnet, EC2 Security Groups, S3 bucket policies and ACLs, IAM user & groups, etc. Deployment part of this section has more developer centric deployment questions. For example, given a use case, will it be better to use pre-configured AMI or CloudFormation for deployment, integration of deployment management tools like Chef with AWS services, and so on.
  • 10. Debugging (20%) This section has questions on the most efficient ways to debug applications deployed on AWS. Questions range from some of the most common mistakes like launching public facing servers in private subnet, improper ACLs for S3 objects, improper IAM policies, etc.
  • 11. Summary Overall the exam is comprehensive and hands-on experience programming with AWS is a must. If you need to get ramped up quickly for the certification, you can consider our Developing Cloud Applications with AWS course.
