Proof of Concept (PoC) and Test Environment for S3-Compatible Storage Solution
Budget: $250 – $750 USD
1. Introduction
1.1. Project Objective
Development and testing of a fault-tolerant S3-compatible object storage solution for commercial offering to hosting provider's clients.
1.2. Scope
The solution is designed for hosting providers offering cloud storage services with S3-compatible API, high availability, and data protection.
1.3. Implementation Options (at Contractor's Discretion)
The contractor shall propose several open-source platforms for PoC implementation with justification. Potential options include:
MinIO (cluster mode with Erasure Coding)
Ceph (RADOS Gateway + RBD/RADOS)
Swift with S3-compatible gateway
Other open-source solutions (contractor may propose alternatives with justification)
2. System Requirements
2.1. Functional Requirements
2.1.1. Core S3 Functionality
Full S3 API support (GET/PUT/DELETE/LIST, multipart upload, etc.)
Multi-tenancy (data isolation between clients)
Quota management, ACLs, access policies
S3 signed URL and pre-signed requests generation
2.1.2. Fault Tolerance and Data Protection
Data replication (minimum 3 copies) or Erasure Coding (e.g., 4+2)
Automatic recovery from disk/node failures
Data integrity monitoring (scrubbing, self-healing)
Hybrid storage support (SSD + HDD) - see section 2.3
2.1.3. Administration
Web interface and CLI for management
API for billing system integration
Operation logging and auditing
Monitoring (Prometheus/Grafana, Zabbix)
2.2. Non-Functional Requirements
2.2.1. Performance
Throughput: ≥1 Gbps per node
Latency: <100 ms for 95% of requests
Support for ≥1000 operations/sec per node
2.2.2. Reliability
Data availability: 99.95% SLA
Protection against simultaneous failure of ≥2 disks
Live migration and updates without downtime
2.2.3. Scalability
Horizontal scaling (adding nodes)
Support for clusters from 3 to 100+ nodes
2.3. Hybrid Storage (SSD + HDD)
2.3.1. Architecture
SSD Tier (hot data):
Object metadata (always on SSD)
Frequently accessed object caching
Automated data migration based on policies
Minimum SSD capacity: 20% of total storage
HDD Tier (cold data):
Primary object storage
Support for automated movement of rarely accessed data
2.3.2. Hardware Requirements
Component Requirements
SSD Enterprise NVMe/SATA, DWPD ≥1, 1-2 TB per node
HDD Enterprise HDD (7200 RPM+, 8-16 TB per node)
Network 10Gbps+, dedicated replication channels
3. Architectural Options (Contractor's Choice)
3.1. MinIO (Distributed Mode)
3.2. Ceph (RADOS + RGW)
3.3. Swift with S3 Gateway
3.4. Other Open-Source Solutions
Contractor may propose alternative platforms (e.g., SeaweedFS) with proper justification.
4. Implementation Phases
4.1. Platform Analysis and Selection
Technology comparison (MinIO vs Ceph vs Swift vs others)
Optimal solution selection based on requirements
Test environment preparation
4.2. PoC Deployment
Software installation and configuration
Fault tolerance setup (Erasure Coding/Replication)
SSD+HDD integration (if custom solution required)
4.3. Testing
Performance: fio, s3-benchmark, wrk2
Reliability: Simulated disk/node failures
Compatibility: Tests with AWS SDK, rclone, s3cmd
4.4. Documentation
Deployment guide
Client API documentation
Scaling recommendations
5. Success Criteria
Fault Tolerance: No data loss with ≥2 disk failures
Performance: Meets stated SLA (1 Gbps, <100 ms)
Hybrid Storage: 3-5x read acceleration for hot data
6. Deliverables
Working S3 storage prototype
Performance test report
Deployment and operation manuals
Production deployment recommendations
Note: All work will be performed on a single approved platform without comparative analysis of alternatives. The contractor must provide detailed justification for the selected platform.
