You’ll drill exactly what matters: cass-operator for lifecycle management, K8ssandra for the full stack, Medusa for backups/restores, Reaper for automated repairs, Prometheus & Grafana for observability, and Stargate APIs (REST, GraphQL, Document) for secure app access.Why this course (and why now)Practice-first design: exam-style questions with short, surgical explanations.Production realism: YAML/Helm values, kubectl output, CRDs, failure modes, runbooks.Speed training: timed/untimed modes, target scoring, per-domain analytics to close gaps.Always actionable: every explanation tells you what to do on a cluster and why.You’ll drill (exam scope, hands-on outcomes)Deploy & scale Cassandra on K8s: StatefulSets, PVC/StorageClass selection, liveness/readiness probes, headless Services.cass-operator: cluster create/scale, rack/zone topology, rolling upgrades, node replacement, safe drains.K8ssandra: opinionated provisioning, day-2 operations, component wiring (Reaper, Medusa, Prometheus, Grafana, Stargate).Medusa: full/incremental backups, S3/GCS/MinIO targets, PITR, restore validation, recovery drills.Reaper: repair strategies, intensity/parallelism tuning, schedule design, error handling, safety rails.Observability: Prometheus metrics, Grafana dashboards, actionable alerts, SLOs for latency/availability.Security: TLS (node-node, clientnode), Secrets, RBAC, ingress/port-forwarding patterns, least-privilege.Stargate APIs: REST/GraphQL/Document access patterns, auth, read/write paths, troubleshooting.Performance & reliability: compaction, JVM/GC, resource requests/limits, anti-patterns to avoid under load.How the practice tests workQuestion → Best answer → Why not the others in 60–120 words—quick to read, easy to retain.Mini-labs inside explanations: copy-paste commands and helm values to try locally.Focus mode: re-quiz weak domains (backups, repairs, observability, security) until stable.Score goals: iterate until your average is 10–15% above your target pass mark.Realistic scenarios you’ll face (and solve)Rolling upgrade goes sideways: drain, decommission, replace node with correct topology keys.Backups exist but restores fail: diagnose Medusa storage paths, credentials, snapshot metadata, PITR windows.Read latency spikes: identify compaction backlog, heap pressure, pod CPU throttling, mis-sized requests/limits.Repairs overload cluster: tame Reaper intensity/parallelism; isolate tables; schedule for off-peak windows.TLS breaks connectivity: verify keystores, truststores, SANs; rotate certs without downtime.Missing metrics or empty dashboards: fix scrape configs, relabeling, namespaces, ServiceMonitors.Ingress vs. port-forward: pick the right exposure pattern for ops vs. app access; lock it down with RBAC.Troubleshooting matrix (what you’ll internalize)Pod restarts, disk pressure, node affinity, gossip issues, hinted handoff, tombstone explosions, repair conflicts, schema mismatches, and storage throttling—mapped to concrete kubectl/helm/Cassandra steps you can execute under pressure.DR & multi-region playbookDesign for recovery: snapshot cadence, retention, encryption, location strategy.Validate restore: table-level checks, repair post-restore, client re-pointing, consistency levels.Failover patterns: topology keys, RF choices, traffic steering, read/write safety during incidents.Who this is forDevOps engineers, SREs, DBAs, platform/infrastructure teams, backend developers integrating via Stargate, and architects building high-availability, low-latency NoSQL on Kubernetes.
