Description

This curriculum engages learners in the same granular decision-making and cross-functional coordination required in multi-workshop technical transformation programs, where infrastructure maps serve as living artifacts guiding architecture governance, incident response, and compliance audits across distributed teams.

Module 1: Defining Application Boundaries and Scope

Determine whether monolithic decomposition should yield service boundaries based on business capabilities or technical cohesion, considering team ownership and deployment frequency.
Resolve conflicts between product managers demanding feature-driven boundaries and architects advocating domain-driven design principles during scoping sessions.
Document legacy system entry points that must remain intact due to regulatory audit trails, even when redesigning surrounding components.
Assess the impact of third-party SLAs on application boundary decisions, particularly when external systems dictate data ownership and access patterns.
Negotiate data ownership between applications when shared databases are unavoidable due to migration timelines or vendor constraints.
Establish criteria for when to expose internal APIs as public endpoints, balancing reuse against security surface expansion.

Module 2: Dependency Discovery and Visualization

Choose between agent-based monitoring and network flow analysis for dependency mapping, weighing precision against infrastructure overhead.
Address discrepancies between documented architecture diagrams and observed runtime dependencies in legacy environments with undocumented integrations.
Classify dependencies as hard or soft based on failure impact, informing circuit breaker and retry policy implementation.
Handle transient dependencies introduced by batch jobs or event-driven workflows that do not appear in steady-state traffic analysis.
Integrate dependency data from multiple sources (logs, APM, CI/CD) when no single source provides complete coverage.
Define refresh frequency for dependency maps in dynamic environments with frequent canary and blue-green deployments.

Module 3: Infrastructure Abstraction and Layering

Decide whether to expose cloud provider-specific features (e.g., AWS Lambda triggers) or abstract through a platform layer, affecting portability and operational complexity.
Implement configuration inheritance across environments while preventing secret leakage through templating systems like Helm or Terraform.
Balance the use of infrastructure-as-code modules versus inline definitions to maintain consistency without stifling team autonomy.
Manage drift detection policies when manual changes are permitted in disaster recovery scenarios, requiring reconciliation workflows.
Select between container orchestration abstractions (e.g., Kubernetes Operators) and declarative manifests based on team expertise and operational burden.
Enforce naming and tagging standards across infrastructure components to support cost allocation and compliance reporting.

Module 4: Data Flow and Integration Mapping

Map synchronous API calls against asynchronous message queues in hybrid integration landscapes, identifying bottlenecks during peak loads.
Determine ownership of message schema evolution in event-driven systems where multiple consumers depend on the same topic.
Trace data lineage across ETL pipelines when source systems lack change data capture capabilities, requiring log scraping or polling.
Implement data residency rules in multi-region deployments by restricting cross-border data flows at the service mesh or API gateway layer.
Classify integration points by criticality to prioritize monitoring and failover mechanisms during incident response.
Document data transformation logic embedded in middleware components that are not visible in application code repositories.

Module 5: Security and Compliance Boundary Enforcement

Define network segmentation rules at the application tier when zero-trust policies require micro-segmentation beyond traditional DMZs.
Map encryption requirements for data in transit across service mesh endpoints, considering performance impact of mutual TLS on east-west traffic.
Identify personally identifiable information (PII) handling paths that require audit logging, even within internal services.
Implement just-in-time access controls for administrative interfaces based on infrastructure maps showing privileged entry points.
Coordinate vulnerability scanning schedules across teams to avoid cascading failures in shared dependencies.
Validate that infrastructure changes comply with regulatory frameworks (e.g., HIPAA, GDPR) by cross-referencing control matrices with deployment pipelines.

Module 6: Observability and Runtime Transparency

Instrument distributed tracing across polyglot services while minimizing overhead on high-throughput transaction paths.
Correlate infrastructure metrics (CPU, memory) with application logs to isolate performance degradation causes in shared environments.
Design log aggregation pipelines that preserve context across container restarts and node rotations without exceeding retention budgets.
Configure alert thresholds on infrastructure health indicators that account for scheduled batch processing spikes.
Map service-level objectives (SLOs) to underlying infrastructure components to identify capacity constraints before violations occur.
Integrate business transaction monitoring with infrastructure telemetry to quantify operational impact of outages on revenue-critical paths.

Module 7: Change Management and Drift Control

Establish change advisory board (CAB) review thresholds based on infrastructure map impact analysis for production modifications.
Automate rollback procedures for infrastructure deployments when health checks detect service degradation post-change.
Track configuration drift between environments using automated diff tools, prioritizing remediation based on risk exposure.
Enforce pre-deployment dependency validation to prevent breaking changes in shared services with undocumented consumers.
Manage technical debt in infrastructure code by scheduling refactoring windows that align with business release cycles.
Document exceptions to standard infrastructure patterns when regulatory or performance requirements necessitate deviations.

Module 8: Cross-Team Coordination and Documentation

Standardize infrastructure diagram notation across teams to ensure consistency in maps used during incident postmortems.
Resolve ownership disputes for shared components by referencing RACI matrices tied to the infrastructure map repository.
Integrate infrastructure maps into onboarding materials for new team members, reducing ramp-up time for complex systems.
Coordinate infrastructure changes across time zones when distributed teams maintain interdependent services.
Maintain versioned snapshots of infrastructure maps to support forensic analysis during security investigations.
Automate map updates from CI/CD pipelines to ensure documentation reflects actual deployed state, not intended design.
