Hello Handian Sudianto,
Greetings! Welcome to Microsoft Q&A Platform.
As Archive Storage Tier is only available for individual blobs it enables tier selection on Blob level for the old existing hot or cold tier also. When you create the storage account, you can select between Hot or Cool tier only and cannot set to Archive tier. After uploading the files, blob properties from Azure portal will allow you to select a blob and change its tier to Hot/Cool/Archive. refer - https://learn.microsoft.com/en-us/azure/storage/blobs/archive-blob?tabs=azure-portal.
Also Archive tier is available only in mentioned regions please refer - https://azure.microsoft.com/en-us/explore/global-infrastructure/products-by-region/?products=storage®ions=all.
