Frequently Asked Questions

Everything you need to know about CloudNexus Storage.

Is CloudNexus Storage compatible with AWS S3?

Yes! CloudNexus Storage is fully S3-compatible. You can use the AWS SDK (boto3, aws-sdk, etc.) with our endpoint URL. No code changes are required — just swap the endpoint and credentials. We support all standard S3 operations including PUT, GET, LIST, DELETE, multipart uploads, and lifecycle policies.

What encryption options are available?

We offer server-side encryption with AES-256-GCM by default, and SSE-KMS for custom key management. For zero-knowledge encryption, you can use our client-side encryption SDK with your own keys. All data is encrypted in transit using TLS 1.3. We also support Bring Your Own Key (BYOK) for enterprise customers.

Are there any egress (download) fees?

No. CloudNexus Storage has zero egress fees for Business and Enterprise plans. Download your data as much as you need without surprise charges. This alone can save you thousands per month compared to other providers.

How does the multi-tier storage work?

Our storage has four tiers: Hot (frequently accessed), Cool (infrequent access, 30-day minimum), Archive (long-term, 90-day minimum), and Deep Archive (compliance, 1-year minimum). Set lifecycle rules to automatically transition objects between tiers based on age or access patterns. Retrieval from Archive is available within 1 hour.

Can I migrate data from AWS S3 or Google Cloud Storage?

Absolutely. We provide a migration tool that seamlessly copies data from S3, GCS, Azure Blob, or any S3-compatible source. Our tool handles large-scale migrations with parallel transfers, resumable uploads, and integrity verification. Most migrations complete in hours, not days.

What compliance certifications do you have?

CloudNexus Storage is certified for SOC 2 Type II, HIPAA, GDPR, PCI-DSS Level 1, and ISO 27001. We also support FedRAMP Moderate and are working toward HITRUST. All compliance reports and audit logs are available upon request.
