Proof of Concept (PoC) and Test Environment for S3-Compatible Storage Solution

Job ID: 39507527

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.
