WebAssembly serves as a crucial element in modern serverless architectures by enabling the execution of untrusted code securely and efficiently. The component model of WebAssembly provides a framework that enhances the performance and security of serverless functions, allowing developers to build more robust applications. Isolation of processes has historically been critical to maintain stability and prevent harmful actions, such as corrupting the kernel of a machine. By leveraging WebAssembly, developers can ensure greater control and flexibility in deployment, alongside improved execution times and reduced payload sizes.
When you're building a serverless platform or functionality service, it means you're basically running untrusted code, and we've had a different solution for this in the past.
The Wasm component model offers a new way to handle untrusted code efficiently, allowing developers to build robust serverless applications while maintaining security and performance.
Isolating code has historically been important because a process can do weird things to your kernel, undermining the stability and security of the server.
Leveraging WebAssembly in serverless architecture introduces advantages, such as faster execution times, smaller payload sizes, and enhanced portability across environments.
