Object Storage Buckets

Scale to petabytes with S3-compatible object storage. Store backups, media, static assets, and datasets with 99.999% durability and global edge distribution.

Quick Start API Reference

Overview

CloudNexus Buckets provide enterprise-grade object storage built for high availability, low latency, and massive scale. Fully compatible with the Amazon S3 API, you can migrate workloads with zero code changes.

Each bucket is a logical container for objects (files). Buckets are globally unique, support versioning, lifecycle policies, and server-side encryption. Data is automatically replicated across availability zones for fault tolerance.

💡 Tip

Bucket names must be globally unique and follow DNS naming conventions. They can contain lowercase letters, numbers, hyphens, and periods.

Key Features

  • S3-Compatible API: Drop-in replacement for existing S3 workflows, SDKs, and third-party tools.
  • 11 9's Durability: Data is replicated across 3+ geographically separated facilities with automatic healing.
  • Lifecycle Management: Automatically transition objects to colder storage tiers or expire them based on time-based rules.
  • Versioning & MFA Delete: Protect against accidental deletion and maintain historical versions of objects.
  • Server-Side Encryption: AES-256 and SSE-KMS support with automatic key rotation and audit logging.

Quick Start

Create a bucket and upload a file using the CloudNexus CLI or any S3-compatible SDK. Below is a CLI example:

Terminal 
# Create a new bucket
cnx storage create-bucket my-app-assets

✓ Bucket created: my-app-assets
  Region: us-east-1
  Endpoint: https://my-app-assets.storage.cloudnexus.io

# Upload a file
cnx storage cp ./logo.png s3://my-app-assets/images/

Frequently Asked Questions

Can I use CloudNexus Buckets with existing AWS S3 code?
Yes. CloudNexus is fully S3 API-compatible. You only need to update the endpoint URL and credentials. Most SDKs, Terraform providers, and CLI tools work out of the box.
How is data replicated for durability?
Objects are automatically replicated across three separate availability zones within a region. Each zone uses redundant storage hardware with continuous checksum verification and automatic repair.
Can I set up automatic backups from my database to a bucket?
Absolutely. CloudNexus provides pre-built integrations for PostgreSQL, MySQL, MongoDB, and Redis. You can also use our CLI or S3-compatible SDKs to script custom backup workflows.
Is there a free tier available?
New accounts receive $200 in credits, which includes 5 GB of standard storage, 1 TB of egress, and 10,000 requests per month for the first 90 days.
