Key Differences Between Cloudflare R2 and S3 Object Storage

Cloudflare R2 and AWS S3 are popular cloud storage solutions with different priorities.

Cloudflare R2 is known for its zero egress fees, S3 API compatibility, and global edge network. It is a cost-effective choice for businesses looking to avoid high data transfer costs.

On the other hand, AWS S3 object storage provides exceptional durability (11 nines or 99.999999999%) and deep integration with AWS services. It is ideal for data lakes, machine learning, and large-scale analytics. However, it comes with egress fees and a stronger dependency on AWS infrastructure.

Below is a detailed comparison of these two storage solutions based on key factors.

API Compatibility

Cloudflare R2: Supports S3-compatible APIs. It allows developers to integrate existing tools, applications, and workflows with minimal adjustments. This makes migration from AWS S3 relatively smooth.
Amazon S3: Uses its own S3 APIs, which are widely adopted and supported by various applications. Many third-party tools and platforms are built to work seamlessly with AWS S3.

Cost Structure

Cloudflare R2: One of the biggest advantages of Cloudflare R2 is its zero egress fees. You can transfer large amounts of data without worrying about additional costs, making it a budget-friendly solution for high-traffic websites and applications.
Amazon S3: AWS S3 applies egress fees when data is transferred out of its storage, which can significantly increase costs, especially for businesses that frequently move large datasets.

Durability and Availability

Cloudflare R2: While it provides high availability, it focuses more on cost savings and flexibility than extreme durability guarantees.
Amazon S3: This delivers 11 nines (99.999999999%) durability, ensuring that stored data remains intact even in the event of hardware failures. This makes it highly reliable for mission-critical storage.

Global Network and Latency

Cloudflare R2: Leverages Cloudflare’s global edge network, which spans over 330+ data centers worldwide. This ensures lower latency and faster access to data, particularly for content delivery and web applications.
Amazon S3: Operates through multiple AWS regions and availability zones. While AWS provides global availability, it primarily follows a centralized cloud model rather than an edge-based approach.

Use Cases

Cloudflare R2: Best suited for businesses that require multi-cloud compatibility, content delivery optimization, and minimal vendor lock-in. It is a great choice for reducing data transfer costs while maintaining performance.
Amazon S3: Ideal for data lakes, machine learning, cloud-native applications, big data analytics, and long-term data storage. Its deep AWS integration makes it a strong choice for businesses already using other AWS services.

Event-Driven Applications

Cloudflare R2: Supports event notifications and queues, allowing businesses to automate processes based on changes in stored data. This is useful for applications that rely on real-time updates.
Amazon S3: This offers robust event-driven workflows with deep AWS service integration. It can trigger AWS Lambda functions, Step Functions, or other AWS services when data is modified.

Vendor Lock-In

Cloudflare R2: Helps to reduce vendor lock-in, making it easier for businesses to adopt a multi-cloud strategy and migrate data between different providers.
Amazon S3: Strongly tied to AWS infrastructure. It offers seamless integration with other AWS services. However, moving data out of AWS can be costly due to egress fees and data transfer restrictions.

When to Choose Cloudflare R2 Over S3 Object Storage?

Cloudflare R2 is a good option if you want to avoid egress fees. Unlike some S3-compatible providers, R2 doesn’t charge for data transfers. This can save you money if your app needs to move data often. If you already use Cloudflare’s CDN, security, or other services, R2 integrates easily with them.

Cloudflare R2 also has a simple pricing model. There are no hidden costs, like fees for API requests or data retrieval, which is common with some S3-compatible providers.
