Multi-AZ offline-capable WMS architecture spanning two AWS availability zones with redundant EC2 instances, Lambda microservices, and ECS containers for warehouse operations. Traffic flows through CloudFront CDN and Application Load Balancers in public subnets to application and data tiers in private subnets, with RDS primary-standby replication, DynamoDB offline queues, and SQS sync orchestration. This design ensures warehouse operations continue during network outages via local sync caching and queued transactions. Fork and customize this diagram on Diagrams.so to adapt subnet ranges, instance types, or add additional AZs for your warehouse footprint.
