Azure offers 3 main options for storing files:
Azure File Store (Supports SMB, no version control)
Azure Blob Storage (No SMB, has version control via apis, tiers for archiving)
Azure Data Lake Storage -Gen2 (No SMB, no versioning), more relevant to Big data/DataLake
AWS also has options to consider:
Amazon Simple Storage Service (S3), similar to Azure Blob Storage with an API and tiers
Amazon FSx, similar to Azure File Store, supports SMB and NFS
Amazon Elastic Block Store (ESB) supports NFS
Office 365/SharePoint Archive option:

Extra SPO/O365 storage costs about $0.20/GB per month, using the SP Achieve service cost 0.05$/TB per month. Also you only get changed for what you use, no pre-provisioned size. Security & compliance is maintained so for old data needed to be archive this is a great easy option.
