Are the storage tiers truly comparable across providers?

The tool maps equivalent tiers based on access patterns and SLAs: S3 Standard / Azure Hot / GCS Standard for frequently accessed data, and S3 Glacier Deep Archive / Azure Archive / GCS Archive for long-term cold storage. While not perfectly identical in every SLA detail, these mappings represent how most organizations compare tiers in practice.

Does the comparison include data egress costs?

Yes. Data egress is often the largest hidden cost in object storage. The tool includes internet egress charges for each provider and highlights the significant pricing differences, especially at higher data transfer volumes where tiered discounts apply.

Can I compare specific regions?

Yes. Pricing varies by region across all three providers. You can select specific regions for each provider to get an accurate comparison for your target deployment geography.
