GCP Apigee multi-cloud platform integrating Google Cloud and Oracle Cloud Infrastructure through hybrid connectivity and centralized API governance. Traffic flows from internet clients through Cloud Armor DDoS/WAF protection and external load balancers into a GCP VPC spanning DMZ, Apigee runtime, GKE private, and connectivity subnets, with Apigee API Platform and Sense providing API management and threat detection across Springboot microservices. Hybrid connectivity via Cloud VPN Gateway and Dedicated Interconnect links the GCP platform to an on-premises Edarat data center and OCI me-jeddah-1 region, where OKE clusters and Oracle Autonomous Database extend the architecture. Cloud Monitoring, Logging, IAM, and KMS provide observability and security across all layers.
