Description

This curriculum spans the design, governance, and operationalization of enterprise-scale data systems, comparable in scope to a multi-workshop technical advisory engagement focused on building and running a modern data platform across cloud and distributed environments.

Define measurable KPIs for big data projects in collaboration with business unit leaders to ensure alignment with revenue, cost, or risk targets.
Select use cases based on feasibility, data availability, and potential ROI using a scoring framework across departments.
Negotiate data access rights with legal and compliance teams when integrating customer behavior data into enterprise analytics platforms.
Decide whether to prioritize real-time analytics or batch processing based on business SLAs for reporting and decision latency.
Establish cross-functional steering committees to review project progress and re-prioritize initiatives as business needs evolve.
Assess the cost-benefit of building internal data science capabilities versus engaging external consultants for specific high-impact projects.
Document data lineage from source systems to business dashboards to support auditability and stakeholder trust.
Balance innovation velocity with technical debt by enforcing architectural review gates at project milestones.

Module 2: Data Governance and Compliance in Distributed Systems

Implement role-based access controls (RBAC) in Hadoop and cloud data lakes to enforce data segregation by department and sensitivity level.
Classify data elements as PII, PHI, or financial under GDPR, CCPA, or HIPAA and apply masking or tokenization in non-production environments.
Configure audit logging in Kafka and data warehouses to track data access, modification, and export events for compliance reporting.
Develop data retention policies that specify deletion timelines for raw logs, processed datasets, and model outputs.
Coordinate with legal teams to respond to data subject access requests (DSARs) involving distributed data stores and backups.
Enforce metadata tagging standards to ensure datasets are properly labeled for sensitivity, source, and usage restrictions.
Conduct quarterly data governance reviews to validate policy adherence across cloud and on-premise systems.
Integrate data classification tools with CI/CD pipelines to prevent deployment of code that violates data handling policies.

Module 3: Scalable Data Ingestion and Pipeline Architecture

Choose between change data capture (CDC) and log-based ingestion for synchronizing transactional databases with data lakes.
Design idempotent ingestion pipelines to handle duplicate messages from message queues like Kafka or Kinesis.
Implement schema validation and evolution strategies using Avro or Protobuf when ingesting data from heterogeneous sources.
Size and tune Kafka topics with appropriate partition counts and replication factors based on throughput and fault tolerance requirements.
Configure backpressure handling in Spark Streaming jobs to prevent pipeline failures during traffic spikes.
Deploy ingestion pipelines across multiple availability zones to ensure high availability and disaster recovery.
Monitor data freshness and latency at each pipeline stage using synthetic heartbeat records and alerting thresholds.
Optimize file formats and compression (e.g., Parquet with Snappy) for cost and query performance in cloud object storage.

Module 4: Data Storage and Warehouse Modernization

Select between data lakehouse architectures (e.g., Delta Lake, Iceberg) and traditional data warehouses based on query flexibility and ACID needs.
Partition and cluster large fact tables in cloud data warehouses (e.g., BigQuery, Redshift) to reduce query costs and improve performance.
Implement zero-copy cloning and branching in lakehouse platforms for isolated development and testing environments.
Define lifecycle policies to automatically transition cold data from hot to cold storage tiers (e.g., S3 Standard to Glacier).
Configure materialized views or summary tables to precompute aggregations for frequently accessed reports.
Manage concurrency and workload isolation using query queues and resource monitors in shared data warehouse instances.
Enforce data quality checks at write time using constraints or pre-commit hooks in transactional table formats.
Plan for cross-region replication of critical datasets to support global analytics and regulatory data residency.

Module 5: Advanced Analytics and Machine Learning Integration

Version control datasets and model artifacts using platforms like DVC or MLflow to ensure reproducibility.
Deploy feature stores to standardize and share engineered features across multiple ML models and teams.
Orchestrate model training pipelines using Airflow or Kubeflow, including hyperparameter tuning and cross-validation.
Monitor model drift by comparing live prediction distributions against baseline training data on a weekly cadence.
Implement A/B testing frameworks to evaluate the business impact of model-driven decisions in production.
Integrate real-time scoring APIs into customer-facing applications with latency SLAs under 100ms.
Apply differential privacy techniques when training models on sensitive datasets to limit re-identification risks.
Containerize ML models using Docker and deploy on Kubernetes to support scalable, versioned inference endpoints.

Module 6: Real-Time Data Processing and Stream Analytics

Choose windowing strategies (tumbling, sliding, session) in Flink or Spark Streaming based on business event patterns.
Handle late-arriving data in stream pipelines using watermarking and allowed lateness configurations.
Deploy stateful stream processing jobs with checkpointing to durable storage for fault tolerance and recovery.
Scale stream processing clusters dynamically based on incoming message rates using auto-scaling groups or KEDA.
Integrate streaming anomaly detection to trigger alerts for sudden changes in transaction volume or error rates.
Join streaming data with reference data from databases or caches using broadcast or lookup join patterns.
Ensure exactly-once processing semantics in end-to-end pipelines by coordinating offsets and transactional sinks.
Measure and optimize end-to-end latency from event generation to actionable insight delivery.

Module 7: Cloud-Native Data Platform Operations

Implement infrastructure-as-code (IaC) using Terraform or Pulumi to provision and manage cloud data platforms consistently.
Configure monitoring and alerting for cluster health, storage utilization, and job failures using CloudWatch, Datadog, or Prometheus.
Apply cost allocation tags to cloud resources to enable chargeback and showback reporting by team or project.
Optimize compute costs by scheduling non-critical workloads during off-peak hours or using spot instances.
Rotate encryption keys and service account credentials on a quarterly basis using automated secret management tools.
Conduct chaos engineering experiments to test resilience of data pipelines under network partitions or node failures.
Enforce secure networking patterns using VPC peering, private endpoints, and firewall rules for data services.
Perform regular disaster recovery drills to validate backup restoration and failover procedures for critical data assets.

Module 8: Performance Optimization and Cost Management

Analyze query execution plans in distributed SQL engines to identify bottlenecks such as data skew or inefficient joins.
Implement data compaction routines to reduce small file problems in object storage and improve scan performance.
Negotiate reserved instance pricing or savings plans for predictable workloads in cloud data platforms.
Use query result caching strategically to reduce redundant computation for common analytical queries.
Right-size cluster configurations for batch jobs based on historical memory and CPU utilization metrics.
Apply data sampling techniques during exploratory analysis to reduce compute costs and iteration time.
Enforce query timeouts and concurrency limits to prevent runaway jobs from consuming shared resources.

Document data model changes and communicate impacts to dependent teams using changelogs and versioned schemas.
Train business users on self-service analytics tools while enforcing governance guardrails on data access and export.
Resolve conflicts between data teams and IT security over encryption, logging, and access protocols during platform upgrades.
Manage stakeholder expectations when data quality issues delay analytics deliverables or model deployments.
Standardize naming conventions, metadata practices, and documentation templates across data teams.
Lead post-mortem reviews after data incidents to identify root causes and implement preventive controls.
Coordinate data platform upgrades with application teams to minimize downtime and backward compatibility issues.
