Supported regions, data platforms, and features

Suggest Edits

Sigma supports various cloud platforms and regions, connections to many data platforms, and some features are supported only on specific data platforms.

Supported cloud platforms and regions

Your Sigma organization is hosted on one of the following cloud platforms:

  • Amazon Web Services (AWS)
  • Microsoft Azure
  • Google Cloud (GCP)

Your cloud deployment is chosen when your Sigma organization is created, and cannot be migrated or changed after creation.

💡

If you're unsure which cloud platform hosts your organization, you can reference it in the Administration portal (if you're assigned the Admin account type). Go to Administration > Account > General Settings, then locate the Site section. The Cloud field identifies the platform hosting your organization.

The following table lists the specific supported cloud regions:

Supported data platforms and feature compatibility

Sigma connects to the following data platforms:

  • AlloyDB
  • Azure SQL Database
  • Amazon Redshift
  • Databricks
  • Google BigQuery
  • MySQL
  • PostgreSQL
