-This article shows you how to configure Application Performance Management (APM) Java agent with init containers in Azure Container Apps, which injects APM solutions without modifying your app image. While you can package the APM plugin in the same image or Dockerfile with your app, doing that binds together management efforts like release and Common Vulnerabilities and Exposures (CVE) mitigation.
+This article shows you how to configure the Application Performance Management (APM) Java agent with init containers in Azure Container Apps. APM helps power observability for your container apps. You can package the APM plugin in the same image or Dockerfile with your app, but it binds together the management concerns, like release and Common Vulnerabilities and Exposures (CVE) mitigation. Rather than binding the concerns together, you can use the Java agent and init containers in Azure Container Apps to inject APM solutions without modifying your app image.
