Amazon S3 client

[arkinform]

It would be good to have Amazon S3 client within Dext framework:

• Fully async implementation
• Support for AWS and other S3 compatible providers (like Minio)
• Support for Path-style and Virtual-hosted-style url formats

In my opinion it's very important for modern enterprise-grade applications.

Hello @arkinform,

This is an excellent request! Standardizing cloud storage integrations is definitely on our radar, and we want to do it in an extensible way.

I have created the specification S53: Cloud Object Storage to address this. Instead of a tight coupling to AWS, we designed a unified interface IDextStorageProvider.

The development will be phased as follows:

1. Phase 1 (Target Goal): Fully async S3-Compatible client (TDextS3StorageProvider) supporting AWS Signature V4, custom endpoints, and both Path-style and Virtual-hosted-style URL formats. This will natively support AWS S3, MinIO, Oracle Cloud Object Storage (OCI), and Cloudflare R2.
2. Phase 2 (Backlog): Native Azure Blob Storage integration under the same interface, alongside other essential cloud providers (e.g. Azure Service Bus, SendGrid, and MongoDB Atlas).

The specification has been officially added as a draft to our backlog. We appreciate your feedback and welcome any community contributions to shape the API design or implement the SigV4 signing mechanisms!

Best regards,
