Course programs
Nine applied tracks spanning domain modeling, communication, observability, resilience, and deployment strategy for backend organizations in Korea and broader APAC time zones.
Domain ModelingBounded Context Studio for Backend Leads
A cohort lab for naming service boundaries, aligning ubiquitous language, and publishing context maps your teams can reuse in production planning.
Service CommunicationEvent Contracts and Async Integration Lab
Design durable messaging between services with schema evolution, idempotency drills, and replay strategies that match how your buses already behave.
ObservabilityProduction Telemetry Design for Microservices
Instrument services without drowning operators: RED metrics, exemplars, trace budgets, and alert fatigue reviews grounded in your dashboards.
Resilience PatternsResilience Patterns Under Realistic Fault Loads
Practice bulkheads, hedging, and graceful degradation with fault injection scenarios that mirror latency spikes instead of cartoon failures.
Deployment StrategyProgressive Delivery for Service Fleets
Compare canary, blue-green, and feature-flag strategies when more than a dozen services ship weekly, including database coupling hazards.
Service CommunicationAPI Gateway and Edge Policy Design Clinic
Clarify authentication flows, rate limits, and header policies at the edge without turning gateways into accidental domain logic hosts.
Domain ModelingData Ownership and Read Model Boundaries
Untangle who owns writes, projections, and cache invalidation when microservices share datasets through events and nightly loads.
ObservabilitySLOs That Survive Reorgs and Vendor Changes
Draft error budgets that connect customer journeys to service graphs, including how to renegotiate SLOs after acquisitions.
Deployment StrategyMesh Advisory Week for Platform Leads
A focused advisory sprint for platform leads balancing internal developer experience with production stability mandates.
