• Subnet A (Public) with a Load Balancer. A unidirectional arrow connects the Internet Gateway to Load Balancer.
• Subnet B (Private) with an OKE cluster having Application Service, Application Deployment with three Pods, 2 worker nodes and a MySQL Custom Resource. A unidirectional arrow connects the Application Deployment to NAT Gateway. A unidirectional arrow connects the worker node to Service Gateway.
