Operations, Monitoring and Troubleshooting
- Monitor OCI resources and services and investigate alerts, availability, capacity and performance-related issues.
- Use OCI Logging, Monitoring, Events and Notifications to support operational monitoring and issue diagnosis.
- Troubleshoot compute, operating system, network, storage and access-related incidents, and document the root cause and resolution.
- Coordinate backups, restores, patching and disaster recovery activities; participate in recovery exercises when required.
- Maintain infrastructure documentation, operating procedures and support handover notes.
Platform and Team Support
- Provide infrastructure support for application deployments and migrations to OCI.
- Support OKE clusters, node pools, worker nodes and OCI Container Registry (OCIR) where the project requires it.
