Find The Resources Which Use Particular User Assigned Managed Identity

I have been busy lately (answering on Q&A, Bicep testing, working, etc.) which prevented me from writing new blog posts but I hope to do more blogging again. This blog post will be a quick tip.

If you have wondered in which resources a particular user assigned managed identity was used you can see that information quickly by using Azure Resource Graph. The query is very simple:

Examples from my Azure Bootcamp 2021 session

At Azure Bootcamp Bulgaria 2021 I have presented "Azure Deployments – Past, Present and Future". In the demos I had two examples:

  • Advanced ARM template templates for deploying Azure SQL Database
  • The above example converted to the new Bicep language

You can find both examples uploaded here. The Bicep example is also published in the Bicep repository examples.

This is just a quick blog post to notify you about me speaking at Azure Bootcamp Bulgaria 2021. If you are interested in Azure deployments or some of the other sessions you can check out the schedule and register.

Tips on creating Azure policies for Azure SQL Databases

Azure SQL Databases is quite a big service and it is also one of the oldest. Because of these two there are a few architectural designs that you should be aware. Some of these are:

  • with every SQL logical server there is a master database resource that is created. This resource is not directly managed but for example when you configure diagnostic settings on server level you need to configure those against the master database resource rather the SQL logical server
  • The SKUs of Azure SQL Databases are mostly divided into DTU and vCore based. Among the vCore based we also have Hyperscale and Serverless variants. You can also have elastic pools for some SKUs and than the databases under those elastic pools inherit their SKUs. Not all Azure SQL SKUs support all of the features of the service. Some of the features that may not be available or have some limitations across different SKUs are:
    • Zone redundancy
    • Hybrid benefit
    • Read replicas
    • Failover Group support – for example not supported on Hyperscale SKUs and supported on Serverless SKUs only auto pause delay is disabled
    • Geo replication
    • Short term backup
    • Long term backup

Among these we also have Datawarehouses (now known as Azure Synapse Analytics) which underneath are the same resource as Azure SQL databases but have completely different options.

Controlling Azure SQL Firewall Rules

Recently on Microsoft Q&A there was question on how you can control Azure SQL Firewall rule in a way that only certain IP addresses are allowed to be configured. Naturally I gave general answer that you can do that via Azure Policy. Initially I didn’t give the person an actual policy as I haven’t done such before. Of course creating Azure Policy definition can be challenging so the person asked him if I can provide him with example.
