Removing unused resources in your Azure account (like load balancers) can help you avoid unnecessary charges on your monthly Azure bill. Whether it's just you picking up after yourself or the dozens of other teams in your company creating resources (and not deleting them ah hem) – this workflow can help to keep your Azure account clean.
This workflow will first look for all Azure load balancers in a Subscription (or optionally, resource group). Then, it will filter that list for the load balancers that have zero back end configurations. Then, it waits for your approval. Finally, once approval has been granted, it will delete the empty load balancers. Problem solved!
For more details, check out our blog post Save time and money by automatically deleting Azure Load Balancers.
Before you run this workflow, you will need the following:
- An Azure Subscription
- An Azure Service Principal with permissions to manage load balancers.
- One or more Azure Load Balancers with zero back end configurations.
