The Innovation of Embedded Function Calling by Cloudflare

June 27, 2024 DNS

Cloudflare, a company known for its web performance and security services, recently unveiled a revolutionary feature - the embedded function calling. This new development marks a significant advancement in their serverless platform, Workers, and is set to redefine the way developers build applications on the edge.

The serverless platform, Workers, allows developers to run JavaScript and WebAssembly applications at the edge, closest to the users. This platform has been a game-changer in the industry, but the Cloudflare team wanted to take it a step further. The introduction of embedded function calling represents a new level of versatility and performance in the serverless world.

The embedded function calling essentially allows developers to call a function directly from their code without having to worry about the complexities of network routing, serialization, and deserialization. This is a significant departure from the traditional approach where developers had to make an HTTP request to call a function.

The traditional HTTP request method comes with overheads such as network latency and computational costs of serialization and deserialization. It also necessitates the management of network failures, making the process complex and inefficient. The embedded function calling, on the other hand, eliminates these overheads, offering a more streamlined, efficient, and reliable approach.

The new feature is as simple to use as calling a JavaScript function. Developers just need to import the function from a Workers module and call it directly in their code. The function can return complex JavaScript objects, including binary data, without the need for serialization or deserialization.

The embedded function calling has shown impressive performance gains during the testing phase. The latency, compared to traditional HTTP requests, is reduced by about 100 times. This is primarily because the function call happens directly in the same JavaScript isolate, bypassing the need for network traversal.

Moreover, the embedded function calling is not just limited to a single worker. Functions from multiple workers can be called in a single request, opening up a world of possibilities for developers to build more complex and sophisticated applications on the edge.

Cloudflare's introduction of embedded function calling is a significant step forward in their mission to build the future of the Internet. This new feature simplifies the development process, reduces latency, and offers more flexibility to developers. It's an exciting development that is set to make a notable impact on the serverless computing landscape.

In conclusion, Cloudflare continues to push the boundaries of what's possible with serverless computing. The embedded function calling is a testament to their innovative approach and commitment to making the Internet a better place. It is a promising feature that is sure to be welcomed by developers around the globe.
