IBM Cloud Object Storage Alternative

IBM Cloud Object Storage is engineered for large enterprise data estates: resiliency options like Cross Region and Single Data Center, Aspera high-speed transfer for moving terabytes, immutable WORM buckets for retention compliance, and Key Protect for bring-your-own-key encryption. Those are real capabilities — and real overhead — when all you want is to store application files and serve them quickly.

Getting started means a Cloud account, a service instance, a resource group, IAM service credentials or HMAC keys, and choosing a resiliency and storage class before you upload anything. files.link is the opposite end of that spectrum on purpose. You sign up, copy an API key, and upload with three calls: POST /v1/files/{folderId} hands back { success, urls:[{ url, id }] }, you PUT the bytes to the presigned url, and you finalize with POST /v1/files/confirm-upload sending { ids:[...] }.

The Authorization header is just the raw API key — no HMAC signing, no Bearer prefix, no service credential JSON to manage. Every file is delivered through an integrated global CDN, so you skip the step of standing up a separate delivery layer in front of your buckets. Migration from IBM COS is a list-and-copy job: enumerate objects with the IBM Cloud CLI or aws-cli pointed at the COS S3-compatible endpoint, sync them down, and replay them through the three-call flow.

The honest tradeoffs: files.link does not offer Aspera-class accelerated transfer for giant single payloads, and it does not provide WORM immutability, so if your requirement is regulated write-once retention or moving multi-terabyte datasets fast, IBM COS is the right tool. For the common case — a product that needs to put files somewhere durable, organize them by project and folder, hand out permanent links or time-limited signed URLs, and have everything load fast worldwide — files.link gets you there with prepaid-credit pricing and a fraction of the setup. You trade enterprise ceremony for a faster path to a working integration.
