In this article, we will explore each of these domains in detail. Understanding the exam content will help you prioritize your study efforts, identify your strengths and weaknesses, and build a solid foundation to pass the exam confidently.
Domain 1: Development with AWS Services
This domain accounts for the largest portion of the exam and focuses on your ability to write code that interacts with AWS services. It tests your knowledge of how to build applications using AWS’s core compute, storage, database, and messaging services.
One key skill is developing code for applications hosted on AWS. This involves understanding different architectural patterns such as event-driven, microservices, monolithic, choreography, and orchestration. For example, event-driven architectures rely on asynchronous events to trigger processes, which is critical when designing serverless applications using AWS Lambda. Microservices architectures break down applications into loosely coupled services, allowing for more scalable and maintainable systems.
Understanding idempotency is also important. Idempotent operations can be performed multiple times without changing the result beyond the initial application. This concept helps developers design fault-tolerant systems that can safely retry failed operations, a common scenario in distributed applications.
You will also need to distinguish between stateful and stateless applications. Stateless applications do not retain client data between sessions, making them easier to scale, while stateful applications keep data that influences the behavior of the system. AWS services like Lambda encourage stateless designs for serverless functions.
Fault-tolerant design patterns such as retries with exponential backoff and jitter, and the use of dead-letter queues are essential topics. Retries with backoff and jitter help avoid overwhelming systems by spacing out repeated requests. Dead-letter queues capture messages that cannot be processed successfully, enabling troubleshooting and recovery.
In addition to architectural knowledge, you will be tested on your ability to write code using AWS SDKs and APIs. This includes creating and maintaining APIs, performing unit testing with tools like AWS Serverless Application Model (SAM), and handling data streaming through services such as Amazon Kinesis.
Developing code for AWS Lambda is another critical part of the exam. You should understand how Lambda functions work, including configuring environment variables, memory allocation, timeouts, concurrency, layers, and triggers. Knowledge of event source mappings, stateless applications, unit testing, and scalability concepts is also tested.
When working with AWS Lambda, you must also be familiar with accessing private resources in a Virtual Private Cloud (VPC), handling event lifecycle and errors with dead-letter queues or Lambda Destinations, and tuning function performance.
Data storage is an equally important topic in this domain. You will be tested on your knowledge of relational and non-relational databases such as Amazon RDS and DynamoDB. Understanding create, read, update, and delete (CRUD) operations, database consistency models, caching strategies, and differences between ephemeral and persistent storage is crucial.
Amazon S3 tiers and lifecycle management are important, as well as serialization and deserialization of data for persistence. Managing data lifecycles and caching data effectively ensures your applications perform optimally and scale well.
Domain 2: Security
Security is a vital aspect of any cloud application, and AWS places strong emphasis on this area in the exam. You will need to understand how to implement authentication and authorization for applications and AWS services.
Knowledge of identity federation using standards like SAML and OpenID Connect is tested, along with how Amazon Cognito manages user pools and identity pools. You should be able to configure resource-based policies, service policies, and principal policies, as well as role-based access control (RBAC).
The principle of least privilege, which means granting only the permissions necessary to perform a task, is a foundational security concept. You will also need to distinguish between AWS-managed policies and customer-managed policies.
Skills include using identity providers to implement federated access, securing applications with bearer tokens like JWT, configuring programmatic access to AWS resources, making authenticated API calls, and defining permissions for principals.
Encryption is another key security topic. You will be tested on encryption at rest and in transit, certificate management with AWS Certificate Manager and Private Certificate Authority, key protection including rotation using AWS Key Management Service (KMS), and the differences between client-side and server-side encryption.
Managing sensitive data in application code is also covered. This includes data classification, the secure handling of environment variables, secrets management using AWS Secrets Manager and Systems Manager Parameter Store, and sanitizing sensitive information to prevent leaks.
Domain 3: Deployment
The deployment domain evaluates your ability to prepare application artifacts and deploy them on AWS. You will be tested on managing dependencies, organizing files and directory structures, and using version control tools such as AWS CodeCommit.
Understanding Lambda deployment packages, layers, and configuration options is crucial. You must also know how to manage container images and use AWS AppConfig, Secrets Manager, and Parameter Store for application configuration data.
Testing applications in development environments is another important skill. You should be familiar with AWS deployment services and how to perform integration testing using mock endpoints in API Gateway. Knowledge of Lambda versions and aliases for managing different deployment stages is necessary.
Automating deployment testing with continuous integration and continuous delivery (CI/CD) workflows is a major part of this domain. You will need to understand how to create test events, deploy API resources across environments, use approved versions for integration testing, and implement infrastructure as code (IaC) templates using AWS SAM and CloudFormation.
Deploying code using AWS CI/CD services like CodePipeline, CodeCommit, and CodeBuild is essential. This includes managing manual and automated approvals, access to application configurations, and applying deployment strategies such as canary, blue/green, and rolling deployments.
Domain 4: Troubleshooting and Optimization
While this domain is less formally defined in the exam blueprint, practical troubleshooting skills are tested throughout the exam. You will be expected to identify and resolve issues related to application performance, security, and deployment failures.
Troubleshooting AWS Lambda functions includes debugging errors, managing timeouts, and tuning memory allocation. You should be comfortable using AWS CloudWatch for logging, monitoring metrics, and setting alarms to proactively detect problems.
Optimizing application performance through caching strategies, database tuning, and efficient use of AWS services is vital. Understanding how to scale applications using elastic load balancing, auto-scaling groups, and serverless technologies ensures that your solutions remain reliable under varying workloads.
