Some Important Services to Focus on for DVA-C02:
- Make sure you are proficient in integrating Amazon EC2 with ELBs and Auto Scaling.
- Learn about the situations where AWS Elastic Beanstalk is a better fit than alternative compute solutions or infrastructure-as-code technologies like CloudFormation or OpsWorks.
- Examine how to include Amazon ECS into a CI/CD pipeline to expedite deployment procedures.
- Examine your options for integrating AWS Lambda with other services and learn how to use Lambda functions to record and process incoming events.
- Amazon RDS/Amazon Aurora: Understand how Amazon RDS integrates with your application, whether through EC2, ECS, Elastic Beanstalk, or other services.
- Amazon DynamoDB: Dive into the DynamoDB documentation, which provides more detailed and informative content than the FAQs.
- Amazon S3 is frequently the first option when it comes to object storage. Examine the many approaches to object security in S3, including bucket policies, ACLs, and KMS encryption.
- Amazon EFS is employed to establish file systems for multiple EC2 instances.
- Amazon Kinesis: Familiarize yourself with Kinesis APIs, sharding concepts, and integration aspects with storage services like S3 and compute services such as Lambda.
- Understand the architecture of Amazon API Gateway, including ideas about stages, methods, and resources. Examine the options for integrating with other AWS services, including CloudFront or Lambda.
- Amazon Cognito: Cognito is frequently mentioned in test questions, particularly when discussing situations requiring web and mobile authentication, Lambda, API Gateway, and DynamoDB.
- Amazon SQS: Investigate timeouts, learn about the features of different SQS queues, and look at how messages are handled in queues.
- Amazon CloudWatch: CloudWatch is the main tool you use to monitor AWS services. Make sure you are aware of the metrics that CloudWatch monitoring offers and determine which metrics call for installing a CloudWatch agent.
- Your cloud environment’s security center is Amazon IAM. It is essential that you familiarize yourself with the many IAM features.
- AWS CodeBuild/AWS CodeCommit/AWS CodeDeploy/AWS CodePipeline: These tools are essential for implementing Continuous Integration/Continuous Deployment (CI/CD) in AWS. Pay particular attention to learning how to use build specifications (Buildspec) to design apps in CodeBuild. Learn how to generate CodeDeploy configuration files (AppSpec) as well. Given that CodeCommit is a Git repository, it is beneficial to know Git. To get knowledge about efficient code deployment management, think about creating a simple pipeline in CodePipeline.
- AWS CloudFormation: Learn how to work with both YAML and JSON forms. Explore the details of stacksets. Make a list of the services that use CloudFormation backend to provision AWS resources, such as SAM, and how it integrates with CI/CD workflows.
Step 5: Assess your Exam Readiness
Before scheduling your exam, make sure to review the whitepapers provided by AWS.
These are some important whitepapers provided by AWS:
- Microservices on AWS – This paper introduces the ways you can implement a microservice system on different AWS Compute platforms. You should study how these systems are built and the reasoning behind the chosen services for that system.
- Running Containerized Microservices on AWS – This paper talks about the best practices in deploying a containerized microservice system in AWS. Focus on the example scenarios where the best practices are applied, how they are applied, and using which services to do so.
- AWS Serverless Multi-Tier Architectures with Amazon API Gateway and AWS Lambda – Learn how to implement common Serverless patterns on applications such as microservices, mobile backends, and single-page applications, and manage multi-tiered applications.
- Practicing Continuous Integration and Continuous Delivery on AWS Accelerating Software Delivery with DevOps – If you are a developer aiming for the DevOps track, then this whitepaper is packed with practices for you to learn. CI/CD involves many stages that allow you to deploy your applications faster.
- Blue/Green Deployments on AWS – Blue/Green Deployments is a popular deployment method that you should learn as an AWS Developer. Study how blue/green deployments are implemented, and using what set of AWS services.
