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.

Module 1: Data Center Architecture for Scalable Big Data Workloads

  • Selecting between on-premises, hybrid, and cloud-native deployments based on data sovereignty, latency, and egress cost constraints.
  • 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.

  • 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.
  • Setting up dynamic resource scaling policies based on job queue depth and historical workload patterns.
  • Implementing node taints and tolerations to isolate workloads requiring specialized hardware (e.g., GPUs).

Module 3: Data Storage and Lifecycle Management

  • 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.
