 So what is Azure Managed Identity? When we're building applications, we need to often access services which require keys or secrets, and we don't want to store those secrets in our code, right? Well, for that, we normally use services like Azure Key Vault to store them securely. But then we have this catch-22 where we need to have a key to access the vault to get our keys. Well, Managed Identity means that we can access these secrets securely using a metadata service that runs on the underlying host without having to store any keys in our code, which makes everyone happy.
