Azure Hybrid cluster settings
This document applies only to Astro Hybrid. To see whether you’re an Astro Hybrid user, click Organization Settings. Your Astro product type is listed under Product Type on the General page.
To create a cluster on Astro Hosted, see Create a dedicated cluster.
Unless otherwise specified, new clusters on Astro are created with a set of default Azure resources that should be suitable for most use cases.
Read the following document for a reference of our default resources as well as supported cluster configurations.
Default cluster values
Supported cluster regions
You can host Astro Hybrid clusters in the following Azure regions:
Modifying the region of an existing Astro cluster isn’t supported. If you’re interested in a region that isn’t listed, contact Astronomer support.
¹ If you want to host Astro in a dedicated account owned by your Organization in one of these regions, you’ll need to contact Microsoft Azure Support to enable the regions. If you require clarification about this requirement, contact Astronomer support.
Supported Azure Database for PostgreSQL instance types
The following Azure Database for PostgreSQL instance types are supported on Astro:
- Standard_D2ds_v4 (2 CPU, 8 GiB MEM)
- Standard_D4ds_v4 (4 CPU, 16 GiB MEM)
- Standard_D8ds_v4 (8 CPU, 32 GiB MEM)
- Standard_D16ds_v4 (16 CPU, 64 GiB MEM)
- Standard_D32ds_v4 (32 CPU, 128 GiB MEM)
- Standard_D48ds_v4 (48 CPU, 192 GiB MEM)
- Standard_D64ds_v4 (64 CPU, 256 GiB MEM)
- Standard_E2ds_v4 (2 CPU, 16 GiB MEM)
- Standard_E4ds_v4 (4 CPU, 32 GiB MEM)
- Standard_E8ds_v4 (8 CPU, 64 GiB MEM)
- Standard_E16ds_v4 (16 CPU, 128 GiB MEM)
- Standard_E20ds_v4 (20 CPU, 160 GiB MEM)
- Standard_E32ds_v4 (32 CPU, 256 GiB MEM)
- Standard_E48ds_v4 (48 CPU, 384 GiB MEM)
For detailed information about each instance type, see the Azure Database for PostgreSQL documentation. If you’re interested in an Azure Database for PostgreSQL instance type that is not on this list, contact Astronomer support.
Supported worker node pool instance types
Each worker node in a pool runs a single worker Pod. A worker Pod’s actual available size is equivalent to the total capacity of the instance type minus Astro’s system overhead.
The following table lists all available instance types for worker node pools, as well as the Pod size that is supported for each instance type. As the system requirements of Astro change, these values can increase or decrease.
If your Organization needs an instance type that supports a larger worker size, contact Astronomer support. For more information about configuring worker size on Astro, see Deployment resources.
