Monitoring of application environments is very important, and there are many kinds of monitoring to consider – infrastructure capacity and availability, as well as application responsiveness and availability to name a few. This is also true in a Platform-as-a-Service (PaaS) environment, such as one running the Red Hat OpenShift Container Platform. The use of containers mean that applications can be built as an immutable image that is deployed and promoted to multiple hosting environments at a rapid pace. This makes monitoring more complex, and the need for dynamic adaptation to the running environment is key to success. But what is the best way to deploy and manage the monitoring solution itself, which in many cases is also running fully or partially within containers? This is where Infrastructure-as-Code (IaC) comes in a useful approach. First, let’s define IaC.
