Data Vault Ensemble Modeling

Demystifying Data Warehousing as a Service

Kent Graziano, Snowflake Computing

We all know that data warehouses and best practices for them are changing dramatically today. As organizations build new data warehouses and modernize their data analytics ecosystem, they are turning to Data Warehousing as a Service (DWaaS) in hopes of taking advantage of the performance, concurrency, simplicity, and lower cost of a cloud-based platform or simply to reduce their data center footprint (and the maintenance that goes with that).

But what is a DWaaS really? How is it different from traditional on-premises data warehousing and big data systems?

In this talk we will:

  • Demystify DWaaS by defining it and its goals
  • Discuss the real-world benefits of DWaaS
  • Describe the key features and design of a DWaaS as exemplified by Snowflake and its novel multi-cluster, shared-data architecture.
  • Discuss key decision factors you should consider when choosing
