4 Core Domains
Here’s a detailed explanation of the four core domains of the AWS Certified Solutions Architect – Associate certification:
1. Design Secure Architectures
Security is the foundation of AWS’s shared responsibility model, and designing secure architectures is paramount in any cloud solution. This domain focuses on building systems that maintain confidentiality, integrity, and availability of data. Key considerations include proper use of Identity and Access Management (IAM). AWS recommends the principle of least privilege—only granting users and applications the permissions necessary to perform their functions. You must understand IAM roles, policies, and access controls across services.
Another important concept is network security, where the Virtual Private Cloud (VPC) enables segmentation of resources. Configuring security groups, network ACLs, and VPC subnets correctly ensures that only trusted traffic reaches sensitive instances. Data protection is also a major element—data should be encrypted at rest using AWS Key Management Service (KMS) or server-side encryption and in transit using TLS protocols. For applications requiring higher compliance, integrating AWS Shield or Web Application Firewall (WAF) helps mitigate attacks.
The domain also includes implementing multi-factor authentication (MFA), auditing with AWS CloudTrail, and automating compliance via AWS Config. By mastering this domain, architects can ensure systems are secure by design, proactively guard against threats, and comply with organizational and regulatory requirements. Security should never be an afterthought—it’s an ongoing process integrated into every AWS solution.
2. Design Resilient Architectures
Designing resilient architectures ensures systems can withstand and recover from failures. In AWS, resilience is achieved by leveraging built-in redundancy, fault tolerance, and elasticity.
A core principle here is high availability (HA). By deploying resources across multiple Availability Zones (AZs), applications can survive localized failures. For example, load-balanced EC2 instances in different AZs ensure seamless failover during outages. Elastic Load Balancing (ELB) distributes traffic automatically across healthy instances, while Auto Scaling Groups (ASGs) dynamically adjust capacity based on demand or health. These features support both high availability and cost-efficiency. Amazon Route 53, AWS’s scalable DNS, adds resiliency at the global level. With features like health checks and routing policies (failover, latency-based), it helps ensure traffic is directed to healthy endpoints. Disaster recovery (DR) strategies also fall under this domain. AWS recommends different DR patterns—backup and restore, pilot light, warm standby, or multi-site—for varying levels of cost and recovery time objectives (RTOs). Resilience further includes data replication strategies, such as cross-region replication for S3, multi-AZ for RDS, and read replicas for scaling and durability.
Ultimately, this domain prepares architects to build systems that remain functional and recover quickly from faults—ensuring minimal business disruption. Designing for failure, rather than assuming uptime, is a best practice in the cloud.
3. Design High-Performing Architectures
High performance in the cloud isn’t just about speed—it’s about responsiveness, scalability, and efficiency under varied workloads. This domain focuses on building systems that can meet performance requirements, regardless of scale or complexity.
The first consideration is compute performance. Choosing the right EC2 instance type (e.g., compute-optimized, memory-optimized, GPU-backed) for specific workloads (e.g., machine learning, web servers) is crucial. Serverless options like AWS Lambda provide auto-scaling and millisecond latency for event-driven applications. Storage performance is another key area. Architects must decide between S3, EBS, EFS, or FSx based on latency, throughput, and IOPS requirements. For high-performance transactional applications, Provisioned IOPS volumes (io1/io2) are ideal. For massive object storage with high durability, Amazon S3 fits best.
Database design also affects performance. AWS training offers tailored options—Amazon Aurora for high-speed relational workloads, DynamoDB for low-latency key-value storage, and Elasticache for in-memory caching. Partitioning, indexing, and choosing the right consistency models are important design decisions. Networking optimization plays a big role too. Placement Groups, enhanced networking, VPC endpoints, and AWS Global Accelerator help minimize latency and improve throughput. Monitoring performance using CloudWatch, setting custom metrics and alarms, and auto-scaling based on usage patterns ensures sustained performance without overprovisioning.
This domain trains architects to match services to workload demands while maintaining speed, responsiveness, and scalability—creating seamless end-user experiences.
4. Design Cost-Optimized Architectures
Designing cost-optimized architectures ensures businesses only pay for what they use, maximizing return on investment. AWS provides a pay-as-you-go model, but poor design can still lead to wasteful spending. This domain teaches architects how to architect solutions that meet requirements while minimizing cost.
One key principle is right-sizing resources. Selecting the correct EC2 instance type and size based on historical usage prevents overprovisioning. AWS Compute Optimizer recommends instance resizing for better efficiency. Auto Scaling ensures that compute resources increase during demand spikes and decrease when idle. Similarly, Lambda’s event-driven model eliminates the need to provision infrastructure for sporadic tasks, greatly reducing costs.
Storage optimization involves choosing the right service for the job. For example, S3 Intelligent-Tiering automatically moves data to the most cost-effective storage class. Amazon Glacier and Glacier Deep Archive offer extremely low-cost options for long-term storage. Reserved Instances (RIs) and Savings Plans provide significant discounts for predictable workloads. Spot Instances can offer up to 90% savings for fault-tolerant applications. Monitoring and alerting via AWS Budgets, Cost Explorer, and CloudWatch allows ongoing cost control. Architects can set alarms when usage exceeds thresholds and identify unused or underutilized resources for decommissioning. Cost optimization also involves data transfer management—using CloudFront for content delivery, VPC endpoints for private traffic, and consolidating accounts using AWS Organizations for volume discounts.
In summary, this domain empowers architects to balance performance and resilience with financial prudence—ensuring solutions are not only effective but also sustainable.
