Fastly adds to investment in WebAssembly for edge app development

Fastly, Inc. announced it has joined the World Wide Web Consortium (W3C) and will participate in the WebAssembly Working Group. The Groups mission is to standardize a size- and load-time-efficient format and execution environment, allowing compilation to the web with consistent behavior across a variety of implementations.

Fastly notes that it continues its contributions to the newly-incorporated Bytecode Alliance, a nonprofit dedicated to creating a new, more secure software ecosystem.

WebAssembly’s secure-by-design future fuels growing popularity

Today’s predominant supply chain models for building software come with inherent weaknesses, which have played significant roles in helping attackers breach critical infrastructure and gain access to billions of people’s personal information. The ecosystem the Bytecode Alliance aims to build, leveraging WebAssembly and other standards and community efforts, will resolve potentially dangerous shortcomings in execution semantics and sandboxed environments within the software supply chain, addressing development gaps in trust and data integrity. This secure-by-default trait has made WebAssembly’s encompassing infrastructure and other emerging standards, such as the WebAssembly System Interface (WASI), progressively popular with organizations and developers that need to deliver safe, performant software across platforms and devices, and to protect against increasingly detrimental system and supply chain vulnerabilities.

“Fastly believes it’s absolutely vital to give developers access to technology that makes it easy and safe to build applications in the languages they are familiar with, using the tools they are comfortable using, and then running that code on the Fastly edge and other environments where performance and security are non-negotiable,” said Tyler McMullen, CTO of Fastly. “Our work with the Bytecode Alliance and W3C further validates our commitment to industry collaboration that makes more secure, performant edge computing and software development an industry-wide reality.”

Fastly spearheads evolution of critical sandboxing and runtime technology

Investment in open source and cross-industry collaboration is vital to improving the security and performance of the internet for everyone. Alongside Bytecode Alliance members, Fastly’s WebAssembly team has specifically prioritized contributing to Wasmtime, a WebAssembly runtime, and Cranelift, an open-source, next-generation code generator for use in WebAssembly to provide sandbox security functionality. Cranelift’s advanced security controls — separately verified by rigorous Fastly, Mozilla, and Bytecode Alliance assessments — are crucial to the speedy yet secure-by-design technology that underlies Fastly’s serverless compute solution [email protected], and is uniquely suited to help power a more secure ecosystem for all who work with, collaborate on, and contribute to WebAssembly.
