Microsoft recommends also enabling blob soft delete and blob versioning to protect individual blobs in a container.

 Applying tags to your Azure resources, resource groups, and subscriptions to logically organize them into a taxonomy. Each tag consists of a name and a value pair. For example, you can apply the name `Environment` and the value `Production` to all the resources in production.
 For recommendations on how to implement a tagging strategy, see Resource naming and tagging decision guide.
 
->**Important** :
-Tag names are case-insensitive for operations. A tag with a tag name, regardless of the casing, is updated or retrieved. However, the resource provider might keep the casing you provide for the tag name. You'll see that casing in cost reports. **Tag values are case-sensitive.**

 An effective naming convention assembles resource names by using important resource information as parts of a resource's name. For example, using these [recommended naming conventions](https://docs.microsoft.com/en-us/azure/cloud-adoption-framework/ready/azure-best-practices/naming-and-tagging#example-names), a public IP resource for a production SharePoint workload is named like this: `pip-sharepoint-prod-westus-001`.
