Description

This curriculum spans the technical and operational rigor of a multi-workshop infrastructure modernization program, addressing the same breadth of concerns as an enterprise advisory engagement focused on stabilizing and optimizing large-scale data platforms.

Designing rack-level power and cooling specifications to support high-density GPU and storage nodes.
Implementing network topologies (e.g., leaf-spine) to minimize latency and avoid bandwidth bottlenecks in distributed data processing.
Right-sizing storage tiers (SSD, HDD, object) based on data access patterns and retention policies.
Integrating out-of-band management infrastructure for remote node recovery during cluster outages.
Planning physical security and access controls for data centers housing sensitive datasets.
Standardizing server hardware configurations to simplify firmware updates and driver compatibility.
Evaluating rack power distribution units (PDUs) with metering capabilities for capacity planning.

Module 2: Cluster Orchestration and Resource Management

Configuring Kubernetes or YARN with custom resource quotas per team to prevent cluster monopolization.

Implementing tiered storage policies using lifecycle rules to move data from hot to cold storage.
Choosing between object, file, and block storage based on application I/O patterns and consistency requirements.
Configuring erasure coding vs. replication for HDFS or object stores based on durability and performance needs.
Designing schema evolution strategies in Parquet or Avro to maintain backward compatibility.
Automating data compaction processes to reduce small file overhead in distributed file systems.
Enforcing data retention and deletion workflows to comply with regulatory requirements.
Validating checksums during data replication to detect silent data corruption.
Planning partitioning and bucketing strategies in data lakes to optimize query performance.

Module 4: Monitoring, Logging, and Alerting at Scale

Deploying distributed tracing systems to diagnose latency in multi-stage ETL pipelines.
Configuring log aggregation from thousands of nodes with log sampling to control ingestion costs.
Setting up alert thresholds for disk utilization, network saturation, and job failure rates.
Correlating infrastructure metrics with application-level performance indicators.
Selecting time-series databases (e.g., Prometheus, InfluxDB) based on write throughput and retention needs.
Implementing role-based access controls on monitoring dashboards to limit sensitive data exposure.
Designing synthetic health checks for critical data ingestion endpoints.
Managing log retention policies to balance auditability and storage costs.

Module 5: Disaster Recovery and High Availability Planning

Defining RPO and RTO for critical data pipelines and aligning replication strategies accordingly.
Implementing cross-region replication for metadata stores like Hive Metastore or Ranger policies.
Testing failover procedures for distributed databases such as Kafka or HBase.
Validating backup integrity by restoring subsets of data to isolated environments.
Documenting runbooks for data rebalancing after node or zone failures.
Using quorum-based consensus (e.g., Raft, Paxos) to maintain cluster state during network partitions.
Staging periodic disaster recovery drills with rollback verification.
Storing encryption keys in geographically dispersed key management systems.

Module 6: Security and Access Governance in Distributed Systems

Integrating Kerberos or OAuth2 for service-to-service authentication in Hadoop ecosystems.
Enforcing attribute-based access control (ABAC) on data lake objects using Apache Ranger or AWS Lake Formation.
Rotating long-lived service account credentials and API keys on a defined schedule.
Implementing encryption at rest using KMS-backed keys with audit trails.
Masking sensitive fields in logs and monitoring outputs to prevent PII exposure.
Scanning cluster configurations for insecure defaults (e.g., open ports, debug endpoints).
Conducting access certification reviews for high-privilege roles quarterly.
Deploying network segmentation to isolate data ingestion, processing, and analytics zones.

Module 7: Performance Tuning and Capacity Planning

Analyzing garbage collection logs to optimize JVM settings for Spark executors.
Adjusting HDFS block size based on average file size and concurrent read patterns.
Right-sizing container memory and CPU limits to prevent node overcommitment.
