Note: This feature is in Public Preview.
UPDATE: Currently, you can use Azure Free Trial subscription to create a Single node cluster which will have one Driver node with 4 cores.
A Single Node cluster is a cluster consisting of a Spark driver and no Spark workers. Such clusters support Spark jobs and all Spark data sources, including Delta Lake. In contrast, Standard clusters require at least one Spark worker to run Spark jobs.
Single Node clusters are helpful in the following situations:
- Running single node machine learning workloads that need Spark to load and save data
- Lightweight exploratory data analysis (EDA)

--------------------------------
To try Azure Databricks, you need to have “Pay-As-You-Go” subscription.
Why can't I use Azure Free Trial subscription?
Azure Free Trial has a limit of 4 cores, and you cannot create Azure Databricks cluster using a Free Trial Subscription because to create a spark cluster which requires more than 4 cores i.e (Minimum 4 cores for Driver type and 4 cores for Worker type).
If you have a free account, go to your profile and change your subscription to pay-as-you-go. Then, remove the spending limit, and request a quota increase for vCPUs in your region. When you create your Azure Databricks workspace, you can select the Trial (Premium - 14-Days Free DBUs) pricing tier to give the workspace access to free Premium Azure Databricks DBUs for 14 days.
Hope this helps.
