Management and Monitoring patterns

Cloud applications run in in a remote datacenter where you do not have full control of the infrastructure or, in some cases, the operating system. This can make management and monitoring more difficult than an on-premises deployment. Applications must expose runtime information that administrators and operators can use to manage and monitor the system, as well as supporting changing business requirements and customization without requiring the application to be stopped or redeployed.

Pattern Summary
External Configuration Store Move configuration information out of the application deployment package to a centralized location.
Health Endpoint Monitoring Implement functional checks in an application that external tools can access through exposed endpoints at regular intervals.
Runtime Reconfiguration Design an application so that it can be reconfigured without requiring redeployment or restarting the application.
