In this 3 part series we are going to learn a few methods for developing an Azure Function that uploads blobs to Azure Storage using the new Azure Blob Storage SDK and the new Azure Identity SDK's DefaultAzureCredential. We'll first get everything running locally without any cloud dependencies via a Azurite. We'll then run the same code locally, but configure it to upload blobs to Azure Storage using a AzureCliCredential. And lastly, we'll learn how to deploy an Azure Function to Azure, that uses Azure Storage and Managed Identities. The three different setups allow you to iteratively develop Azure Functions without the cost and inner-loop dev cylce overhead of deploying everything to Azure on every code change.
