Some older or third-party AWS SDKs don't properly handle Web Identity Token credentials used by IRSA. Ensure the SDK version is >=1.12.262 (Java), boto3>=1.16.35, or use AWS SDKs with explicit web identity token support.
Use backup tools that support chunked uploads (e.g., Rclone, Restic, or Duplicacy). These split large archives into smaller pieces, enabling resumable transfers and better error handling.
Yes, .NET Aspire entered GA in 2024 and is designed for enterprise cloud-native development, especially within Azure. However, tight coupling to Microsoft tooling may limit multi-cloud flexibility.
