S3-Compatible Object Storage
S3-compatible object storage provides an API-level replacement for AWS S3, letting applications switch providers without rewriting integration code. European providers increasingly offer zero-egress pricing and data residency within the EU, which matters for workloads subject to GDPR data transfer constraints. The key differentiators are API compatibility depth, multipart upload performance, and lifecycle policy support.
