OCI Production Three-Tier Architecture — OCI architecture diagram

About This Architecture

OCI production three-tier architecture with Internet Gateway, WAF, and Flexible Load Balancer protecting public app tier across multiple Compute instances in an autoscaling pool. Traffic flows through Route Table and Dynamic Routing Gateway to private database tier hosting MySQL Database System with standby replica and backup storage. Network segmentation via NSG and Security Lists enforces least-privilege access between tiers, while Monitoring tracks health across all layers. Fork this diagram to customize subnets, instance types, or failover policies for your OCI workload. Advanced deployments can extend with additional regions or hybrid connectivity via Dynamic Routing Gateway.

How do I design a production three-tier application architecture on OCI with load balancing, autoscaling, and database replication?

This OCI diagram shows a complete three-tier production setup: Internet Gateway and WAF protect inbound traffic, Flexible Load Balancer distributes to autoscaling Compute instances in the app tier, and Security Lists restrict access to MySQL Database System with standby replica in the private database tier. Network compartmentalization via NSG and Route Tables enforces least-privilege access while
