This illustration is a high-level architecture diagram that shows how you can use Oracle Application Performance Monitoring in Oracle Management Cloud to monitor the performance metrics of applications running in Oracle Container Engine for Kubernetes. Icons represent Oracle Application Performance Monitoring agents, virtual network firewall, applications running in container nodes, a user, Oracle Management Cloud, and Oracle Application Performance Monitoring. A cloud icon on the top right of the image inside a box depicts Oracle Cloud. A box representing a Oracle Container Engine for Kubernetes container is placed inside the Oracle Cloud box. The Oracle Container Engine for Kubernetes contains two nodes represented by two boxes, each of which contains an application and an Oracle Application Performance Monitoring agent. A virtual network firewall is outside the cloud. The flow of information uses https to go from the cloud, through the virtual network to a box containing Oracle Management Cloud. Inside the Oracle Management Cloud box is Oracle Application Performance Monitoring. End users use https to access Oracle Management Cloud.
