The image shows the OpenTelemetry Operator 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 a private subnet that includes an OpenTelemetry Operator instance, an Oracle Cloud Infrastructure Kubernetes Engine (OKE) cluster with 2 microservices replicas, and access to an OCI APM Java Agent Docker image in Oracle Container Registry. A secondary VCN includes a private subnet that provides Oracle Autonomous Transaction Processing as an example microservices deployment.
