Create Cloud Storage Connection File (Data Management)

Summary

Creates a connection file for ArcGIS-supported cloud storage. This tool allows existing raster geoprocessing tools to write cloud raster format (CRF) datasets into the cloud storage bucket or read raster datasets (not limited to CRF) stored in the cloud storage as input.

Usage

• You must provide the necessary information to make a cloud storage connection—such as access key ID, secret access key string, and bucket name—to run this tool. You can also use alternate authentication methods using the Provider options parameter.

  Learn more about connecting to cloud stores

• The tool outputs a binary cloud storage connection file (.acs) in ArcGIS Cloud Storage format.

• The raster dataset stored in the cloud storage can be referenced through a file path such as c:/temp/amazons3.acs/someraster. If the dataset is stored in a folder in the bucket, the folder name must be included in the path, for example, c:/temp/amazons3.acs/foldername/someraster.

• This tool supports connections to Amazon Simple Storage Service (S3) buckets, Microsoft Azure Blob Storage containers, Microsoft Azure Data Lake Storage Storage Gen2, Alibaba Cloud Object Storage Service (OSS) buckets, Google Cloud Storage Service (GCS) buckets, WebHDFS, MinIO, and Ozone Object Storage Service buckets.

• A custom endpoint URL can be used to support any S3 compliant object storage or CNAME record.

• The tool validates the credentials provided at run time. If the connection cannot be made, the tool returns a warning.

• OAuth 2.0 authentication with Azure Active Directory is supported with user-interactive login for Azure and Azure Data Lake Storage Gen 2. See Connect to authentication providers from ArcGIS Pro for configuration. Once configured and the user is signed in, the authentication parameter becomes active for Azure and Azure Data Lake Storage Gen2. Region and Endpoint will be retrieved from the configuration.

• Support for user-assigned managed identities using Entra ID on an Azure virtual machine is available for Azure and Azure Data Lake Storage Gen2.

• Role-based access control (RBAC) is available for Amazon,Azure, and Google cloud providers. Keeping all authentication parameters empty while using an EC2 or Azure virtual machine or Google Compute Engine will enable ArcGIS AllSource to access Blob storage using IAM roles or Azure RBAC. For Amazon, IMDSv1 and IMDSv2 are supported.

  Microsoft Azure Data Lake Storage Storage Gen2 follows the same options as Azure but provides true directory support and atomic operations using a DFS endpoint. Some network errors during cloud operations are retried following exponential backoff.

  For performance considerations and additional information, see the GDAL virtual file systems documentation.
