# Big data analytics system (SaaS)

A system following the big data analytics pattern is available as a software as a service (SaaS) based deployment using ArcGIS Online and ArcGIS Velocity. 

> [!NOTE]
> **Note**
> The capabilities offered in this deployment pattern differ significantly from those available in [big data analytics systems deployed on Apache Spark](as-apache-spark.md).
ArcGIS Velocity is a cloud-native add-on capability for ArcGIS Online. It enables users to ingest data from the Internet of Things (IoT) platforms, message brokers, or third-party APIs. It also helps users process, visualize, and analyze real-time data feeds; store those feeds as big data; and perform fast queries and analysis.

ArcGIS Velocity supports big data analysis against real-time data and observations that are stored, as well as on ingested data from feature layers and cloud-based data stores such as Amazon S3, Azure Blob Storage, and Azure Cosmos DB. While ArcGIS Velocity on ArcGIS Online does deliver a big data analysis system as SaaS, ArcGIS Velocity is used primarily in conjunction with real-time data analysis. As such, the deployment details for ArcGIS Velocity are described in the [real-time data streaming and analytics pattern as SaaS](/en/framework/system-patterns/real-time-data-streaming-and-analytics/deployment-patterns/as-saas.md) pattern.
