Lesson 01
Production Cloud-Native Backend Systems Explained
Trace source, image, runtime, workload, traffic, and business evidence without collapsing their boundaries.
Cloud-Native Backend topic cluster
Cloud-Native Backend Operations
A production learning path for OCI artifacts, Kubernetes application boundaries, capacity, safe rollout, observability, and verified backend recovery.
12 reading lessons ยท 1 capstone guide
Connect artifact identity to verified recovery.
Move through workload ownership, configuration, lifecycle, capacity, availability, rollout, observability, and incident evidence.
Lesson 02
OCI Container Images and Runtime Boundaries Explained
Separate OCI image, distribution, runtime, CRI, registry, and Kubernetes responsibilities.
Lesson 03
Production Container Images, Dockerfiles, and Supply Chain
Build minimal non-root artifacts and bind provenance, SBOM, scan, and signature evidence to a digest.
Lesson 04
Kubernetes Pods, Deployments, and Services for Backend Apps
Connect controller reconciliation, Pod lifecycle, Service selection, EndpointSlices, and request routing.
Lesson 05
Kubernetes Configuration, Secrets, and Workload Identity
Operate configuration, credential rotation, Spring precedence, and workload identity without disclosure.
Lesson 06
Kubernetes Probes and Graceful Shutdown for Spring Boot
Assign startup, restart, traffic eligibility, termination, and durable outcome responsibilities correctly.
Lesson 07
Kubernetes Resource Requests, Limits, and JVM Containers
Budget scheduling, throttling, process memory, pools, and downstream capacity together.
Lesson 08
Kubernetes Scheduling, Disruption, and High Availability
Distribute failure domains and interpret disruption policy without treating replicas as availability proof.
Lesson 09
Kubernetes Horizontal Pod Autoscaling for Backend Services
Scale from owned signals while protecting startup lag and finite dependency capacity.
Lesson 10
Kubernetes Rolling Updates and Safe Backend Releases
Coordinate immutable images, surge, readiness, termination, rollback, and compatible database change.
Lesson 11
Kubernetes Observability and Debugging for Backend Workloads
Trace user impact through controllers, Pods, containers, telemetry, dependencies, and durable state.
Lesson 12
Production Kubernetes Backend Incident Troubleshooting
Narrow common workload symptoms from user impact to reversible mitigation and verified recovery.
Capstone lab
