Understanding these security controls helps candidates evaluate how to build secure AWS architectures.

6. Learn High Availability and Disaster Recovery Strategies

Cloud architects must design systems that can continue operating when infrastructure failures, service interruptions, or unexpected events occur.

AWS provides several services and architecture options that support availability and disaster recovery.

Multi-Availability Zone Deployment

Deploying application components across multiple Availability Zones can reduce the impact of a failure affecting one location.

Auto Scaling

Amazon EC2 Auto Scaling can adjust the number of instances based on defined conditions and application demand.

Load Balancing

Elastic Load Balancing distributes incoming traffic across multiple targets and helps maintain application availability.

Backup and Recovery

AWS Backup supports centralized backup management across supported AWS services. Candidates should understand backup policies, retention, and recovery requirements.

Disaster Recovery Approaches

Study backup and restore, pilot light, warm standby, and multi-site strategies. Understand the differences in recovery time objectives, recovery point objectives, and infrastructure costs.

These concepts help candidates evaluate architecture options based on business continuity requirements.

7. Understand AWS Cost Optimization

Cost optimization is another important skill for cloud architects. Organizations need to select services and configurations that meet technical requirements without creating unnecessary infrastructure expenses.

Candidates should understand how AWS pricing models and resource management options affect overall cloud costs.
