Issue in finding OS in which my cluster runs

[Abishrp]

During the configuration of job compute cluster, I didn't mention any OS details. How can i find which OS my cluster is running?
Also, Is there any way to get pricing details of all instances with different category  Job Compute - premium  , All Purpose - Premium etc. in AWS Databricks

You can find the OS for your runtime in the system environment information in release notes, for example for Runtime 16.1 it can be found in: https://docs.databricks.com/en/release-notes/runtime/16.1.html#system-environment which is Ubuntu 24.04.1 LTS.

As for pricing you can use the pricing calculator: https://www.databricks.com/product/pricing/product-pricing/instance-types
