Wasabi Cloud Storage API
S3-compatible cloud object storage with flat-rate pricing designed for cost-effective backup, archival, and active storage — marketed as 80% cheaper than Amazon S3.
Best When
You need S3-compatible cloud storage at significantly lower cost and your workloads are not compute-adjacent to AWS.
Avoid When
Your storage is on AWS where S3 data transfer fees are free, or you need sub-millisecond latency with CDN integration.
Use Cases
- • Cost-effective backup and archival storage replacing S3 or Glacier
- • Large file and media asset storage for applications
- • Offsite backup destination for servers and databases
- • Video and podcast media storage for streaming applications
- • AI/ML training data and model artifact storage
Not For
- • Low-latency edge delivery (use CDN in front of Wasabi)
- • Very small files at high frequency (minimum 4KB charge per file)
- • Compute-adjacent storage where AWS S3 data transfer is free
- • Teams needing serverless compute tightly coupled with storage
