Cloud Storage Guide →
A comprehensive reference for architecting, optimizing, and securing data storage workloads on the CloudNexus platform.
Overview
CloudNexus provides a unified, multi-tier storage ecosystem designed for modern applications. Whether you're serving static assets, running high-IOPS databases, or managing collaborative file systems, our infrastructure scales elastically while maintaining enterprise-grade durability and security.
Storage Types
Object Storage (S3-Compatible)
Designed for unstructured data at scale. CloudNexus Object Storage delivers 99.999% durability across geographically distributed edge nodes. Ideal for backups, media archives, CI/CD artifacts, and CDN-backed content.
- Horizontal scalability with zero capacity planning
- RESTful API & CLI access (AWS SDK compatible)
- Versioning, lifecycle rules, and cross-region replication
- Integrated tiering: Hot, Cool, Archive, and Glacier
Block Storage
Low-latency, high-throughput volumes attached directly to compute instances. Built on NVMe arrays with synchronous replication for databases, container volumes, and transactional workloads.
- IOPS up to 100K with single-digit ms latency
- Thin provisioning with auto-scaling snapshots
- Multi-attach support for clustered databases
- Transparent failover across availability zones
File Storage (NFS/SMB)
Shared network storage optimized for POSIX/SMB compatibility. Perfect for legacy app migration, HPC workloads, content management systems, and developer home directories.
- Mountable from multiple instances simultaneously
- POSIX ACLs and Kerberos/LDAP integration
- Automatic metadata caching for read-heavy workloads
Choosing the Right Type
| Workload | Recommended | Why |
|---|---|---|
| Static Assets / CDN Origin | Object Storage | Unlimited scale, CDN-optimized, cheap bulk storage |
| PostgreSQL / MySQL | Block Storage | Low latency, consistent IOPS, journaling safe |
| Legacy App Migration | File Storage | Direct path mapping, shared access, NFS/SMB native |
| AI/ML Datasets | Object Storage + Cache | Bulk ingest, parallel reads, tiered cost structure |
Performance Tuning
Maximize throughput and minimize latency by aligning your application architecture with storage capabilities.
Object Storage Optimization
# Upload large dataset with 16 concurrent parts
ncs object upload s3://ml-pipeline/training-data ./dataset.tar \
--multipart-size 100MB \
--concurrency 16 \
--storage-class hotBlock Storage Tuning
For database workloads, align your I/O block size with your filesystem stripe width. Use the `fio` benchmark suite to profile latency percentiles (p99) under load.
Security & Compliance
All storage services encrypt data at rest using AES-256 and in transit via TLS 1.3. You retain full control over keys through our integrated KMS or BYOK options.
- Bucket Policies: Granular IAM bindings with least-privilege enforcement
- Immutable Retention: WORM capabilities for regulatory compliance (SOX, HIPAA, GDPR)
- Network Isolation: VPC endpoints and private DNS resolution
- Audit Logging: Real-time activity streams to CloudWatch/Splunk
Cost Optimization
Storage costs can scale quickly without proper governance. Implement these strategies to maintain efficiency:
- Lifecycle Automation: Transition cold data to Archive tier after 90 days. Auto-delete temporary CI/CD artifacts after 7 days.
- Deduplication: Enable block-level dedup on backup volumes to reduce storage footprint by up to 70%.
- Capacity Rightsizing: Use the Cost Explorer dashboard to identify underutilized block volumes and snapshot-only retention.
- Egress Management: Route cross-region transfers through CloudNexus Transfer Acceleration to avoid premium bandwidth fees.
Quick Start
Initialize your first storage bucket and mount a block volume in under 60 seconds using the CloudNexus CLI:
ncs storage create-bucket --name app-assets --region us-east-1 --versioning enabled
ncs volume create --type block-nvme --size 200GB --name db-primary
ncs instance attach-volume --instance i-08f3a21 --volume vol-99x7k2p --device /dev/xvdb
