The Azure Cloud Adoption Framework (CAF) is a set of guidance and best practices from Microsoft.
It comes with reccomendations as well as sample ARM templates on how to establish various sized Azure tenants, subscriptions and policies.
CAF can come across as a bit too much to handle for smaller organizations.
And as data professionals, we rarely deal with infrastructure as code or think too much about networking and so on.
But there is so much in CAF we as data professionals can use in our projects.
In september 2022, Microsoft even released the Data Management and Analytics scenario for CAF.

And while this is aimed at large organizations (Enterprise Scale), the guidance and the best practices contains loads of useful information for companies of all sizes.
