The Extensions Framework in Apache CloudStack is designed to provide a flexible and standardised mechanism for integrating external systems and custom workflows into CloudStack’s orchestration process. By defining structured hook points during key operations—such as virtual machine deployment, resource preparation, and lifecycle events—the framework allows administrators and developers to extend CloudStack’s behaviour without modifying its core codebase.
