The image shows the shared file system architecture for monitoring and tracing microservices with Oracle Cloud Infrastructure Application Performance Monitoring Cloud Service (APM). The process flow is described in the surrounding text.

The architecture includes a single Oracle Cloud Infrastructure (OCI) region that provides APM and APM Domain services. Users access microservices from the internet. The APM browser agent captures the user actions done on the browser.

The region includes 2 virtual cloud networks (VCNs). The primary VCN includes 2 subnets: a public subnet that includes a shared file system and a private subnet that includes an Oracle Cloud Infrastructure Kubernetes Engine (OKE) cluster. The OKE cluster includes 2 microservices replicas, the APM Java Agent, and a persistent volume that connects to the shared file system. A secondary VCN includes a private subnet that provides Oracle Autonomous Transaction Processing as an example microservices deployment.
