Azure
Microsoft provides a generous (but limited) annual gift of Azure credits to help support C3.ai DTI-sponsored research.
If you're interesting in using Azure resources for a current C3.ai DTI project, please contact the DTI team at help@c3dti.ai.
Private data
Microsoft Azure infrastructure can support your program of compliant stewardship of data in most scenarios. If your data requires special attention, please let us know when asking for Azure resources.

cloud-config: VM configuration in a text file
Many standard Azure VM images (including examples running Ubuntu, CentOS, and Windows) run the cloud-init service. This service allows you to submit a yaml-formatted cloud-config text file as part of the VM creation request. This cloud-config file encodes your set of VM configuration instructions, including software package installations. This enables you to define your VM's configuration in a text file, which can be documented, shared, re-used, and even managed under version control. DTI researchers are strongly encouraged to consider using the built-in cloud-init service in Azure VMs to help manage deployments.
To read more about using cloud-config files with Azure VMs, see this documentation:
https://docs.microsoft.com/en-us/azure/virtual-machines/linux/using-cloud-init
This page features many cloud-config file examples:

Note: the cloud-init service is not Azure-specific, with support from other cloud providers as well.
