Recovery needs to recreate the working service and its required data after a machine or process is lost. Which artifacts and state need protection, and how should the restore be checked?
How can I improve Kubernetes performance without guessing?
A performance change should improve the measured workload without sacrificing correctness or wasting capacity. Which measurements and bottlenecks should be considered first?
What should I check first when Kubernetes fails?
A failure needs to be narrowed down before settings are changed or operations retried. Which evidence best separates application errors from environment and dependency problems?

Check supported version skew, removed APIs and add-on compatibility before a cluster upgrade. Validate workloads on the target version and respect disruption budgets during node replacement. Control-plane, node, CNI and storage-driver changes need coordinated testing rather than one undifferentiated upgrade step.
