Module 01 · 3 lessons
Container artifact and runtime boundaries
Trace reviewed source into an immutable OCI artifact, registry, runtime bundle, and least-privileged Java process.
14 reading lessons · 1 deterministic capstone
Operate the whole release boundary, not just the Pod.
Follow one Spring order service from an immutable OCI image through traffic, capacity, rollout, evidence, and verified business recovery.
Five ordered modules · approximately 5 hours
Move from immutable artifact to production evidence.
Stable Kubernetes and OCI contracts form the core. Version-sensitive behavior stays cited and explicitly bounded.
Module 02 · 3 lessons
Kubernetes application boundaries
Connect controllers, Services, configuration, identity, probes, traffic eligibility, and graceful application termination.
Module 03 · 5 lessons
Capacity, availability, and scaling
Budget JVM and dependency resources, distribute failure domains, and scale from signals without inventing capacity.
Module 04 · 3 lessons
Release and production operations
Coordinate mixed-version rollout, collect safe evidence, mitigate reversibly, and verify customer and durable-state recovery.
Module 05 · Capstone lab
Capstone lab
Run six deterministic readiness, surge, termination, stall, and capacity scenarios without contacting a cluster.
Browser-only capstone
Model a rollout, then identify the evidence the model cannot provide.
The lab explains readiness, surge, unavailability, termination, and modeled capacity. It is not a benchmark, calculator, dry-run, or production verification.

FAQ
Cloud-Native Backend course questions
Does this course require access to a Kubernetes cluster?
No. Manifests and commands are explanatory. The capstone is a deterministic browser model and neither connects to nor changes a cluster, registry, cloud account, or paid service.
Is this a Kubernetes certification course?
No. It is a production backend operations path for engineers who already understand Java, Spring, HTTP, and basic backend architecture.
Does a completed Deployment rollout prove the release succeeded?
No. Controller convergence must be followed by user, dependency, migration, asynchronous, and durable business-state verification.
Can the capstone size production replicas or resources?
No. Its steps and per-Pod capacity are explicit teaching inputs, not measurements, benchmarks, forecasts, or deployable advice.
