Cluster Orchestrator (Infrastructure Node) is a set of internal components for managing resources, processing requests, and supporting CirrusGrid system maintenance.
For high availability, CirrusGrid platform is running on two infrastructure nodes. With a help of synchronization each server is running as an independent identical copy of CirrusGrid infrastructure.
The components of infra node are running in a separate virtual Virtuozzo Containers for Linux on CentOS and are responsible for:
- Templates configuration and clustering binding
- Environment’s lifecycle management
- Applications deployment
- Scalability management
- Handling requests via Shared Resolver
- Logs and statistics
