Cloudflare Workers vs Fastly: What are the differences?
Introduction:
Cloudflare Workers and Fastly are both edge computing solutions that help companies improve the performance and security of their websites and applications.
1. **Execution Environment**: Cloudflare Workers utilize V8 isolates to run JavaScript code, while Fastly relies on a custom Wasm runtime that executes code precompiled from C and Rust.
2. **Pricing Model**: Cloudflare Workers operate on a pay-as-you-go pricing model based on the number of requests and execution time, whereas Fastly charges based on bandwidth and additional features such as Image Optimizer and Web Application Firewall.
3. **Caching Capabilities**: Fastly offers advanced caching features like surrogate keys and edge dictionaries, allowing for more granular cache control compared to Cloudflare Workers, which have limited caching options.
4. **Integration with CDNs**: Fastly is designed as a CDN with edge computing capabilities, allowing seamless integration between content delivery and serverless computing, while Cloudflare Workers are an extension of Cloudflare's CDN services.
5. **Networking Features**: Fastly provides real-time logs and network visibility tools, empowering users to monitor and optimize traffic flow at the edge, something that Cloudflare Workers lack in-depth features in.
6. **Developer Ecosystem**: Cloudflare Workers have a more extensive developer community with resources like templates, examples, and documentation, making it easier for developers to get started and troubleshoot issues compared to Fastly's less extensive community support.
In Summary, Cloudflare Workers and Fastly differ in their execution environment, pricing model, caching capabilities, integration with CDNs, networking features, and developer ecosystem.
