About This Architecture
Multi-AZ e-commerce architecture leveraging CloudFront CDN, AWS WAF, Route 53, and API Gateway for global content delivery and DDoS protection. Application tier spans two availability zones with Auto Scaling Groups of EC2 t3.large instances behind Application Load Balancers, while ElastiCache Redis and Memcached clusters provide session and product caching across AZs. Aurora PostgreSQL primary-replica database with db.r6g.2xlarge instances ensures data consistency and failover capability, with CloudWatch and CloudTrail monitoring operational health and compliance. This architecture demonstrates multi-tier separation, cross-AZ redundancy, and caching strategies essential for handling Harbolnas flash-sale traffic spikes. Fork and customize this diagram on Diagrams.so to adapt instance types, subnet ranges, or add additional services like SQS or SNS for asynchronous workloads.
