Cohort signal
612 hours of guided cloud infrastructure labs—structured for teams leaving on-prem behind
Think Zonex pairs English-language curriculum with mentor markup on your diagrams, scripts, and runbooks. We focus on networking, compute, containers, and monitoring tracks that mirror operational work in Korea.
Average satisfaction 9.1/10 from internal surveys after the last three Seoul-area intakes.
Programs worth pinning in your notes
Four open cohort highlights—filters on the full listing help you match schedule and depth.
VPC Patterns for Production Workloads
Design isolated networks, subnet tiers, and routing that mirror how teams ship services in Seoul and Busan data regions.
Compute Autoscaling Under Real Traffic
Tune launch templates, warm pools, and signals so services stay responsive without overspending on idle capacity.
Container Images Hardening Sprint
Shrink attack surface in images, enforce provenance checks, and wire scanners into CI without slowing developers down.
Service Mesh Traffic Surgery
Control retries, timeouts, and canaries with mesh primitives while keeping dashboards readable for on-call peers.
The flow — from intake diagram to production checklist
Map the system you actually run
Bring redacted diagrams; mentors annotate with routing and risk notes.
Ship labs with checkpoints
Each week ends with a short stakeholder-ready artifact.
Operational handover
Runbooks and rollback language your on-call peers can follow.
From our cohorts — specifics, not slogans
“The VPC Patterns for Production Workloads NAT lab finally made sticky egress decisions click—I reused the week-2 diagram in our internal design review.”
“Quota games in Kubernetes Platform Starter were playful but serious.”
“Burn-rate lab in Observability Signals trimmed three duplicate pages without losing the latency story—still a bit noisy week one, but mentors answered fast.”
