Comparing Data Warehouse Clouds

AWS Redshift vs Oracle Autonomous Data Warehouse Cloud



Amazon vs Oracle: Data Warehouse Services, How do They Compare?


Emerging information technology trends in the Cloud have the power to transform organizations. In the data management and analytics space, two key Cloud service offerings have arrived that touch on this theme; Amazon’s Redshift and Oracle’s Autonomous Data Warehouse Cloud (ADW).

Amazon’s Redshift is a data warehouse based on PostgresSQL and runs on general purpose hardware.

Oracle’s Autonomous Data Warehouse Cloud (ADW) is a data warehouse based on Oracle Database and runs on Oracle Exadata, an Engineered System designed for high performance Oracle Database workloads.

Both services simplify the provisioning, maintenance, and optimizations for data warehouse workloads in the Cloud, and both promote “no database administrators are required” and “load and pull” approaches to data analytics. In other words, users just start the service, define tables, load data, and then run their queries.

In this paper, Viscosity North America (Viscosity) shares their findings from a series of benchmarks comparing the performance of Redshift and Autonomous Data Warehouse Cloud (ADW).

*This paper does not cover Cloud configuration, manageability or on-going supportability. This will be included in a follow-up document.

Performance Benchmarks

As both Redshift and ADW services are fully managed and autonomous (e.g. no manual intervention is required to tune analytic queries), the goal of this exercise was to quantify “out of the box” response times for data loading, query performance, and query throughput, on similarly sized configurations.


What tests did Viscosity perform?

A Data Load test to determine overall database ingest time.

Serial Query Execution testing

Query Throughput tests, including a more complex query to determine of volume of executions per hour.

The Cost

“Well, which one is cheaper?”  This is the most popular question to ask and the hardest to answer.

This paper includes a brief price performance comparison, and Viscosity plans to come out with a more in-depth paper on pricing alone.

Because it is not the same answer for everyone, it is highly recommended that you have a third party vendor do an analysis of your environment, budget, and priority needs to determine the most cost effective path for you.
