Cloudflare R2 Object Storage: Zero Egress Fee Cloud Storage Solution

What is Cloudflare R2?

Cloudflare R2 is a distributed object storage service designed for storing unstructured data (such as images, videos, website content, etc.). It helps developers and individual users store and distribute data at low costs, especially suitable for setting up image hosting, hosting static resources, or building cloud-native applications. Target users include developers, personal website owners, content creators, and SMEs requiring global data access.

Why Choose Cloudflare R2?

1. Zero Traffic Fees: No egress traffic fees when accessing or downloading stored data, significantly reducing cloud costs.
2. Cost-Effective Free Tier: Offers 10GB of free storage, 1 million write operations, and 10 million read operations per month, covering basic needs of individual users.
3. Global Acceleration & Security Protection: Leverages Cloudflare's global CDN network (covering 275 cities) for high-speed data distribution, with default DDoS protection.
4. No Vendor Lock-in: Compatible with S3 API, supporting seamless migration from other cloud storage (e.g., Amazon S3, Google Cloud Storage).

Core Features

1. Super Eater Migration Tool: One-click migration of data from Amazon S3 or Google Cloud Storage to R2, preserving original metadata, supporting full or incremental migration.
2. S3 API Compatibility: Compatible with mainstream S3 tools, libraries, and plugins (e.g., PicGo), allowing integration into existing workflows without code changes.
3. Serverless Integration: Natively supports Cloudflare Workers, enabling function deployment on the edge network for real-time data processing or permission control.

How to Start Using Cloudflare R2?

1. Registration & Activation: Visit Cloudflare's official website to register an account, select the "R2" service in the dashboard. First-time activation requires credit card or PayPal verification (no charges within the free tier).
2. Create a Bucket: Click "Create Bucket", recommended to choose the Asia-Pacific region to reduce access latency for domestic users.
3. Upload & Access Data: Upload files via drag-and-drop, or configure API keys using S3-compatible tools (e.g., PicGo). Enable "r2.dev subdomain" to obtain public access links.

Tips for Use

1. Prefer Asia-Pacific Nodes: Choose the Asia-Pacific region (e.g., Singapore) when creating a bucket to reduce access latency for domestic users.
2. Enable Public Access: If public data access is needed (e.g., image hosting), enable "r2.dev subdomain" in bucket settings, and configure CORS policies to avoid cross-domain issues.
