Key Concepts and Domains Tested

The AWS Certified Solutions Architect – Associate exam is divided into four primary domains, each focusing on a different aspect of AWS architecture. Understanding the weighting of each domain can help you prioritize your study efforts.

1. Domain 1: Design Resilient Architectures (30%)

This domain focuses on building fault-tolerant and highly available systems. Key topics include:

• Designing highly available and fault-tolerant systems: Learn how to design systems that can withstand failures, including understanding AWS services like Auto Scaling, Elastic Load Balancing (ELB), and Route 53.
• Choosing the right storage solution: Be familiar with Amazon S3, Glacier, EBS, and EFS for data storage.
• Implementing disaster recovery: Understand AWS strategies for backup, data replication, and recovery, such as cross-region replication and backup plans.

2. Domain 2: Define Performant Architectures (28%)

This domain focuses on creating systems that can handle high performance under varying workloads. Key topics include:

• Selecting the right compute and storage resources: AWS EC2 instances, Lambda functions, and different storage types for performance optimization.
• Optimizing application performance: Using caching, CDNs (CloudFront), and optimizing network configurations.
• Designing scalable applications: Load balancing, Auto Scaling, and database scaling techniques.

3. Domain 3: Specify Secure Applications and Architectures (24%)

Security is a key part of AWS architecture. This domain covers topics like:

• Identity and access management (IAM): Understanding IAM roles, policies, and user management to control access to AWS resources.
• Encryption and data protection: Using services like AWS Key Management Service (KMS), CloudHSM, and encryption options for data in transit and at rest.
• Designing secure network architectures: VPCs, subnets, security groups, and Network Access Control Lists (NACLs).

4. Domain 4: Design Cost and Operationally Efficient Architectures (18%)

This domain focuses on optimizing for cost and operational efficiency:

• Cost optimization strategies: Choosing the right instance types, using AWS pricing models like Reserved Instances, Spot Instances, and AWS Cost Explorer to track costs.
• Operational excellence: Implementing monitoring and automation tools like AWS CloudWatch, CloudTrail, and CloudFormation to ensure efficient management of resources.
