Description

This curriculum spans the technical and operational disciplines required to design, deploy, and sustain efficient application infrastructure in large-scale environments, comparable in scope to a multi-phase internal capability build led by platform and SRE teams.

Module 1: Architectural Decision Frameworks for Efficiency

Select between monolithic and microservices architectures based on team size, deployment frequency, and operational overhead tolerance.
Define service boundaries using domain-driven design to minimize inter-service coupling and reduce infrastructure sprawl.
Evaluate the cost and complexity of maintaining API gateways versus direct service-to-service communication in hybrid environments.
Implement feature toggles to decouple deployment from release, reducing environment proliferation and promoting reuse.
Choose containerization over virtual machines when rapid scaling and consistent build-to-deploy pipelines are required.
Assess the long-term maintenance burden of custom orchestration logic versus adopting managed Kubernetes services.

Module 2: Infrastructure as Code (IaC) Governance

Enforce IaC linting and validation in CI pipelines to prevent configuration drift and non-compliant resource creation.
Structure Terraform modules with versioned inputs to enable reuse while isolating environment-specific overrides.
Implement state file locking and remote backend storage to prevent race conditions during parallel deployments.
Balance the granularity of IaC components—over-modularization increases dependency management complexity.
Rotate and audit cloud provider credentials used by IaC tools to mitigate long-term access exposure.
Define ownership and change approval workflows for shared infrastructure modules across teams.

Module 3: Cloud Resource Optimization

Right-size compute instances by analyzing CPU, memory, and I/O metrics over multiple business cycles to avoid over-provisioning.
Implement auto-scaling policies with cooldown periods and predictive scaling to balance cost and performance.
Use spot instances for stateless, fault-tolerant workloads while designing for termination handling and data persistence.
Tag all cloud resources with cost center, owner, and environment metadata to enable accurate chargeback reporting.
Schedule non-production environments to start and stop during business hours using automated runbooks.
Negotiate reserved instance commitments only after validating sustained usage patterns over six months.

Module 4: CI/CD Pipeline Efficiency

Cache dependencies and build artifacts across pipeline runs to reduce execution time and external API calls.
Parallelize test suites across stages to minimize feedback loop duration without overwhelming test environments.
Restrict pipeline-triggered deployments to specific branches to prevent accidental production promotions.
Enforce pipeline immutability—once a build artifact is created, it must be redeployed without modification.
Monitor pipeline success rates and failure modes to identify flaky tests or infrastructure instability.
Isolate staging environments from development to prevent configuration contamination and false performance signals.

Module 5: Observability and Monitoring Strategy

Define SLOs with measurable error budgets to guide incident response and feature deployment pacing.
Instrument applications with structured logging to enable efficient querying and correlation across services.
Configure alert thresholds using historical baselines rather than arbitrary percentages to reduce noise.
Limit the volume of high-cardinality metrics to prevent cost spikes and storage bottlenecks in monitoring systems.
Correlate logs, metrics, and traces using a shared context ID to accelerate root cause analysis.
Rotate and archive telemetry data based on retention policies aligned with compliance and debugging needs.

Module 6: Data Management and Storage Efficiency

Choose between relational and NoSQL databases based on query patterns, consistency requirements, and scaling needs.
Implement data lifecycle policies to transition cold data from high-performance to archival storage tiers.
Use connection pooling to reduce database overhead from frequent short-lived application connections.
Index database queries based on actual access patterns, not assumptions, to avoid performance degradation.
Encrypt data at rest and in transit using KMS-managed keys with periodic rotation policies.
Replicate critical databases across availability zones with automated failover testing schedules.

Module 7: Security and Compliance Integration

Embed security scanning tools in CI/CD pipelines to detect vulnerabilities before deployment.
Enforce least-privilege access for service accounts and avoid using admin roles in automation scripts.
Conduct regular drift detection between deployed infrastructure and IaC templates to identify unauthorized changes.
Isolate workloads with regulatory requirements into dedicated accounts or VPCs with strict network controls.
Document data flows and storage locations to support audit requests and GDPR/CCPA compliance.
Automate patching schedules for OS and middleware components based on criticality and change windows.

Module 8: Cross-Team Collaboration and Operational Handoffs

Define runbooks for common incidents with clear escalation paths and decision authority.
Standardize environment naming and tagging conventions across development, QA, and operations teams.
Conduct blameless postmortems after outages to identify systemic issues, not individual failures.
Rotate on-call responsibilities with adequate training and shadowing to prevent burnout.
Establish SLIs for internal services to set expectations between consuming and providing teams.
Use shared dashboards and status pages to align visibility across technical and business stakeholders.
