Extensions are plug-ins that enhance Elastic Compute Service (ECS) instances with runtime environments (Java, Python, PHP), monitoring agents (CloudMonitor agent), and management tools (BT panel). With CloudOps Orchestration Service (OOS) Quick Setup, you can install, update, or uninstall extensions on ECS instances across multiple regions in a single operation.
This topic covers multi-region extension deployment. To manage extensions for a single region, see Extensions.
