AWS recently launched AWS certification program. Lack of Certification from AWS was a big problem in the AWS ecosystem, so its certification is really exciting. I registered for the exam straight away and gave the exam today. I am glad to say I cleared the exam for AWS Certified Solutions Architecture, and I am sharing my experiences.
Types of AWS Certification
Under the AWS certification program AWS will provide three kinds of Certifications:
- AWS Certified Solutions Architect
- AWS Certified SysOps Administrator
- AWS Certified Developer
Under each of these different verticals AWS will have three different levels in future: 1) Associate, 2) Professional, and 3) Master. For now, AWS has only offered the AWS Certified Solutions Architect certification and only for Associate level. AWS says that the rest of the certifications are coming later in 2013.
What does AWS Solutions Architect Certification consists of?
According to AWS: “Earning an AWS Certified Solutions Architect – Associate Level demonstrates you have the ability to identify and define requirements for an AWS-based application, as well as follow best practices for building secure and reliable applications on the AWS platform.”
My experience: The certification exam was very comprehensive, and it covered almost all the services like EC2, VPC, EBS, S3, Route 53, IAM, RDS, SQS, DynamoDB, etc. Although a majority of the questions were based on popular services like VPC, EC2 and S3. And although the questions about these services were more high-level having hands-on knowledge will definitely be useful. A note here that from the exam, brand new services like RedShift, SES and OpsWork were missing, possibly because AWS realized that not everyone have had a chance to use them yet.
The exam is divided into four sections with different percentage representation:
1. Designing highly available, cost efficient, fault tolerant, scalable systems (60%)
This is by far the most important section of the certification with 60% representation. A lot of questions were simulations of what an architect would have to figure out when he designs an application on top of AWS. For example, characteristics of an application with multiple AZ deployment, deploying in multiple regions, what kind of AWS services would one use for a given use case, characteristics of VPC subnets, difference between private and public subnets, high-level costing topics like reserved-instances vs spot-instances, knowledge of strength and weaknesses of various services, etc .
2. Implementation/Deployment (10%)
This section deals with various deployment management scenarios. This includes Auto Scaling, Custom AMIs, difference between EBS backed AMI vs S3-Backed AMI (legacy AMI), what happens to data stored in EBS, ephemeral storage, etc. in various scenarios like instance reboot, termination, etc. It also contains questions on the best instance type, EBS types, etc. for a given use case.
3. Data Security (20%)
This section has questions about various data encryption techniques in S3, various data protection mechanism in EC2 like security groups, use of IAM roles and users, etc. This also had use case kind of questions about what would be best method to protect data give a particular use case/scenario.
4. Troubleshooting (10%)
This section had various questions about how you would troubleshoot most common errors in AWS. This contains things like trouble logging into EC2 instance, trouble with VPC setup, common mistakes with S3 ACLs, etc. Another important topic here is disaster recovery and how it is implemented on AWS.
