5Maintaining and automating data workloads

• 5.1Optimizing resources and automation

  Understand minimizing cost while ensuring resources for business-critical processes, deciding persistent vs job-based Dataproc clusters, automating with Cloud Composer DAGs and repeatable scheduling, and capacity management with BigQuery Editions and reservations.

• 5.2Monitoring, troubleshooting, and fault tolerance

  Understand observability of data processes (Cloud Monitoring, Cloud Logging, BigQuery admin panel), troubleshooting errors/billing/quotas, and fault tolerance (running in multiple regions/zones, preparing for corruption/missing data, replication and failover).
