Architecture patterns are where individual decisions become complete systems.
While pillars explain how to make specific decisions and topics organize what decisions you’ll face, patterns show how everything fits together in production-ready architectures.
These aren’t theoretical patterns. They’re the recurring enterprise architectures that AWS Solutions Architects design repeatedly—and that SAP-C02 tests repeatedly.
In the AWS Certified Solutions Architect Professional (SAP-C02) exam, Global Scalability represents the pinnacle of architectural complexity. This pattern focuses on designing systems that span multiple AWS Regions to provide low-latency access to a global user base and achieve high levels of business continuity.
🏗️ Core Architectural Patterns #
When solving global-scale scenarios, the exam tests your ability to balance Latency, Consistency, and Cost.
1. Global Traffic Routing #
How users reach your application from across the world.
- Route 53: Latency-based, Geolocation, and Geoproximity routing.
- AWS Global Accelerator: Using the AWS private network to bypass the public internet via Anycast IP.
- Amazon CloudFront: Edge caching for static and dynamic content.
2. Multi-Region Data Consistency #
The most difficult trade-off in SAP-C02.
- Amazon Aurora Global Database: Storage-based replication with < 1 second typical latency.
- Amazon DynamoDB Global Tables: Multi-active, last-writer-wins reconciliation.
- Amazon S3 Cross-Region Replication (CRR): Asynchronous replication for compliance and backup.
📚 Key Decision Pillars (Deep Dives) #
To master this pattern, you must understand the following decision-making frameworks:
- Active-Active Multi-Region Architecture: Understanding write-local/read-global patterns.
- Route 53 Resolver for Hybrid DNS: Connecting global VPCs with on-premises DNS.
- CloudFront & Global Accelerator Patterns: Choosing the right edge acceleration strategy.
- Aurora & DynamoDB Global Data Patterns: Solving data sovereignty and latency issues.
