Built for Resilience & Speed

Our storage engine is distributed across multiple availability zones with automatic replication.

🔄

Auto-Replication

Synchronous cross-AZ replication ensures zero data loss during regional failures.

🔐

Encryption at Rest

AES-256 + RSA-2048 by default. Bring your own keys (BYOK) with HSM integration.

S3 Compatible API

Drops in to replace AWS S3, MinIO, or Wasabi without code changes.

📊

Lifecycle Policies

Automate transitions between tiers and expiration rules to control costs.

Designed for Modern Applications

Whether you're serving media, storing backups, or running analytics, we've optimized for it.

🎥

Media & Content Delivery

Native integration with CloudNexus CDN for sub-50ms global content delivery. Automatic format conversion and on-the-fly image optimization.

💾

Backup & Disaster Recovery

Immutable object locking (WORM) protects against ransomware. Automated tiering to Cool/Glacier reduces long-term retention costs by up to 80%.

📈

Big Data & Analytics

High-throughput read paths optimized for Spark, Presto, and Databricks. Parallelized object retrieval for petabyte-scale datasets.

🛒

SaaS & User Files

Multi-tenant bucket policies, fine-grained IAM access controls, and audit logging compliant with SOC2 and GDPR.

Transparent, Pay-as-You-Go

Only pay for what you use. No egress fees for the first 1TB/month.

Common Questions

How does CloudNexus Storage ensure data durability?

We use a distributed erasure coding algorithm across 3+ availability zones. Every object is automatically replicated, achieving 99.999999999% (11 nines) durability without manual intervention.

Can I migrate existing AWS S3 buckets to CloudNexus?

Yes. Our API is 100% S3-compatible. You can use `rclone`, `aws s3 sync`, or our migration tool to transfer data with zero downtime. DNS propagation typically takes under 5 minutes.

Are there egress fees for CDN distribution?

The first 1TB of monthly outbound traffic is free. Traffic distributed through our integrated CloudNexus CDN is billed at $0.04/GB, which is 50% lower than traditional cloud providers.

Do you support immutable compliance buckets?

Yes. We support S3 Object Lock and Government Compliance modes. You can enforce WORM (Write Once Read Many) policies for up to 7 years, protecting against deletion and overwrites.
