Platform and application ownership
Managed Kubernetes delivers an agreed scope of cluster lifecycle and infrastructure operations as a service. Application code, images and business logic do not automatically become the provider's responsibility. Identify owners for the control plane, worker nodes, network, storage and ingress. Define the application team's deployment and configuration privileges explicitly.
Why upgrades need a process
An upgrade is more than running a new binary. Check API compatibility, add-ons, storage drivers and application behavior. Use a test environment, a planned maintenance window and a rollback approach. Verify supported versions during discovery and plan before a version reaches end of life. Workload downtime tolerance affects maintenance design.
Observability and capacity
Node health alone does not describe the user experience. Monitor application error rates, response times, resource use and storage capacity together. Define who receives an alert and what response it triggers. Requests, limits, scaling and spare capacity should follow actual usage. Budget control is also part of operational design.
Where F2Cloud DevOps fits
F2Cloud DevOps considers managed Kubernetes, CI/CD infrastructure and development zones together with network and security engineering. Ask for separate definitions of cluster scope, maintenance, monitoring and application ownership. Considering container security, secret management and pipeline access in the same architecture makes the platform more than a group of servers.
Pre-decision checklist
- Separate platform and application owners.
- Request maintenance and version plans.
- Consider data and cluster recovery together.
