1. Storing and Retrieving 3D Models in Azure Blob Storage


    To store and retrieve 3D models in Azure Blob Storage using Pulumi, you will need to set up an Azure Blob Storage account, create a container, and then use blobs for storing your 3D model files. Blobs are ideal for serving images or documents directly to a browser, and Azure provides various types of blobs such as block blobs for text or binary data, append blobs for log files, and page blobs for frequent read/write operations.

    Here is a step-by-step Pulumi Python program that accomplishes this:

    1. Set up the Azure Blob Storage Account: This is where all your data objects, including 3D models, will be stored.
    2. Create a Storage Container: Containers hold sets of blobs. All blobs reside within a container.
    3. Upload a Blob with a 3D Model: Blobs can contain any type of data, such as 3D model files (typically .obj, .fbx, .dae, etc.).

    Now, here's a Pulumi program that implements these steps:

    import pulumi import pulumi_azure_native as azure_native # Initialize a Pulumi resource group for organizing resources resource_group = azure_native.resources.ResourceGroup("resource_group") # Create an Azure Blob Storage account (General-purpose v2 accounts) storage_account = azure_native.storage.StorageAccount("storage_account", resource_group_name=resource_group.name, sku=azure_native.storage.SkuArgs( name=azure_native.storage.SkuName.STANDARD_LRS), kind=azure_native.storage.Kind.STORAGE_V2) # Create a storage container within the storage account container = azure_native.storage.BlobContainer("container", account_name=storage_account.name, resource_group_name=resource_group.name) # For demonstration, let's assume we have a 3D model file named "model.obj" in the current directory. # We'll use Pulumi's FileAsset to read this file and upload it as a Blob. model_blob = azure_native.storage.Blob("model_blob", resource_group_name=resource_group.name, account_name=storage_account.name, container_name=container.name, source=pulumi.FileAsset("./model.obj"), # Path to the 3D model file type=azure_native.storage.BlobType.BLOCK_BLOB) # Export the URL of the blob blob_url = pulumi.Output.concat("https://", storage_account.name, ".blob.core.windows.net/", container.name, "/model.obj") pulumi.export("BlobUrl", blob_url)

    This Pulumi program will provision the necessary Azure resources to store your 3D models. Here's what each part of the program does:

    • Resource Group: Organizational container for Azure resources, giving you the ability to manage them collectively.
    • Storage Account: Provisioned to store and manage the blob containers and blobs.
    • BlobContainer: Represents a container which is a logical grouping for your blobs.
    • Blob: Represents the 3D model object that we're uploading.
    • BlobUrl: A constructed URL that points to the uploaded 3D model which can be used to access the model programmatically or in a browser if public access is allowed.

    To manage the assets, such as 3D model files, we use Pulumi's FileAsset which reads file content and creates a blob with that content in Azure Blob Storage.

    Please note: The above code assumes that you have an existing model.obj file in the current working directory. Also, by default, the blob is private and cannot be accessed without proper authentication. If you need to make it publicly accessible, you will need to set additional properties on the container or blob.

    Remember to use the correct Azure region and account settings, and ensure you have the necessary permissions and Azure credentials configured in your environment to run the program successfully. After running this program, you'll have a blob URL that points to your 3D model, which you can use to retrieve the model.
