WebAssembly (WASM) is emerging as a promising evolution in virtualization, offering a compilation target that enables the "compile once, run anywhere" capability across diverse platforms, including Linux, Windows, and Mac, without the need for virtual machines. This binary instruction format supports lightweight and near-native performance, making it suitable for both frontend and backend development, with the added advantage of sandboxed execution for enhanced security. WASM's standardization efforts are supported by organizations like the W3C and the Cloud Native Computing Foundation (CNCF), aiming to ensure its interoperability and security across web, cloud, edge, and IoT applications. The introduction of the WebAssembly System Interface (WASI) and the WASM Component Model further simplifies developer experience by enabling interoperable software components and application-level primitives. WASM is ideal for high-performance workloads like Functions as a Service, edge computing, and IoT devices, and is already being utilized by companies like Adobe for cost-efficient and secure execution of untrusted code. Despite being relatively new, WASM is backed by a strong open-source community, and its adoption is anticipated to grow as part of the cloud-native landscape alongside established technologies like Kubernetes.
