Scaling to new heights with Amazon Redshift multi-cluster architecture (ANT339)

The key takeaways from the video transcription can be summarized as follows:

Single Cluster Challenges

  • Single compute cluster can lead to resource contention and interference between different workloads (streaming ingestion, batch ingestion, reporting, BI, etc.)
  • Monolithic architecture makes it difficult to scale and size compute based on individual workload needs
  • Charging back usage to different business units/departments is challenging in a single cluster setup

Multicluster Architectures

  • Allows for isolation of different workloads onto separate compute endpoints (hubs and spokes)
  • Enables sizing compute based on the unique requirements and SLAs of each workload
  • Facilitates chargeback to different business units/departments based on their usage
  • Leverages Red Shift's managed storage layer and compute separation to enable these multicluster patterns

Red Shift Multicluster Capabilities

  • Red Shift supports writing to shared data sets from multiple compute endpoints
  • Provides centralized data governance and access control using AWS Glue Data Catalog and Lake Formation
  • Allows for mixing of provisioned and serverless compute based on workload needs
  • Supports cross-account and cross-region access to shared data sets

GE Aerospace's Journey

  • Moved from on-premises to AWS, then evolved to a multicluster architecture
  • Driven by growing demands, diverse workloads, and shrinking latency requirements
  • Adopted dedicated clusters for specific workloads and saw benefits in terms of performance, cost, and operational efficiency
  • Learned importance of workload analysis, metric monitoring, and cost transparency to drive architectural decisions

Best Practices

  • Create separate compute endpoints (hubs/spokes) for each workload or business unit
  • Size compute based on workload needs, using a mix of provisioned and serverless
  • Leverage centralized data governance using AWS Glue Data Catalog and Lake Formation
  • For single cluster setups, migrate to multicluster using snapshot/restore and data sharing

The video provides a comprehensive overview of the challenges with single cluster architectures, the benefits of multicluster patterns, and practical guidance on how to evolve your data platform using Red Shift's capabilities.
