Fastly has launched a Beta version of its C++ SDK for Fastly Compute, targeting developers who need high performance for demanding applications. C++ is known for its speed and control, and this SDK integrates that with Fastly's global network and WebAssembly (Wasm) runtime. It allows developers to run optimized C++ code close to users, enhancing performance and streamlining workflows. The SDK includes familiar C++ features along with bindings to Fastly's edge capabilities like KV Stores and Config Stores. The C++ SDK aims to unlock new functionalities, enabling core business logic to run at Fastly's network speed. Use cases include gaming, where low-latency matchmaking and player synchronization are critical; Industrial IoT, which requires efficient data processing from numerous devices; and interactive media, where leveraging existing C++ libraries can save development time. Fastly emphasizes that the combination of C++ and Wasm allows for rapid cold starts and efficient memory usage, leading to better performance and security. Developers can integrate C++ logic with other languages like Rust or JavaScript, fostering a polyglot architecture. This means they can handle intensive tasks in C++ while using other languages for simpler operations. The SDK also supports asynchronous network operations to maintain performance and is compatible with existing VCL and Edge Side Includes (ESI). Fastly encourages developers to test the SDK with their current C++ workloads and provides resources like a GitHub repository and documentation for getting started.
