Alternatives to Amazon S3

Google Cloud Storage
Decision brief →
Same tier / hyperscaler object storage

Google Cloud Storage is the alternative for GCP-native teams that want tighter integration with BigQuery, Vertex AI, and Google's data pipeline tools without the cross-cloud overhead of using S3 from GCP infrastructure.

Azure Blob Storage
Decision brief →
Same tier / hyperscaler object storage

Azure Blob Storage is the natural choice for Azure-native workloads where keeping data and compute in the same cloud eliminates egress fees between services and simplifies IAM integration with existing Azure Active Directory policies.

Cloudflare R2
Decision brief →
Step-sideways / egress-sensitive alternative

Cloudflare R2 eliminates S3's egress fees entirely—the single biggest cost driver for high-bandwidth workloads. For teams serving data to end users at high frequency, R2 can reduce storage bills by 40–60% vs S3's $0.09/GB egress pricing at the same storage volume.

Step-down / cost-driven storage

Wasabi is the cost-first alternative for large backup and archive footprints—storage at ~$0.0068/GB versus S3's $0.023/GB with no egress fees for most use cases. Best for teams storing large volumes of infrequently accessed data where S3's per-GB rate becomes a significant budget line.
