Fastly’s security DNA: a look at our culture of safety, privacy, and trust
Fastly's heritage of security runs deep — far beyond our portfolio of web application and API security products. Our philosophy of developer empowerment, focus on community, and values-driven culture each contribute to our security DNA in an important way. And we'd like to tell you how.
State at the edge
With the introduction of Compute, Fastly provides a richer model for the CPU. WebAssembly, powered and secured by the Lucet compiler and runtime, unlocks essentially arbitrary code execution within each request lifecycle. This raises the immediate question: what would a richer model for memory, or state, look like?
Why Compute does not yet support JavaScript
Building our own compiler toolchain allows Compute to be both performant and secure. It also means we have to bring developers’ most-loved language into the fold in the right way.
Fastly and devs invest in WebAssembly | Fastly
WebAssembly is helping to lay the foundation for the future of edge computing. And together with the Bytecode Alliance and the developer community at large, we’re investing in new technologies to make WebAssembly easier and more performant.
Evaluating new languages for Compute
Learn about our process and approach for evaluating which new languages our serverless compute environment — Compute — will support next.
How Lucet and Wasmtime make a stronger compiler, together
In our latest Bytecode Alliance initiative, we’re working to marry the benefits of Lucet and Wasmtime — ultimately creating a more seamless, secure, and speedy WebAssembly runtime and compiler.
Internet changed in 2019, expect more in 2020 | Fastly
Take a look back at 2019’s major shifts in internet infrastructure, and understand what they mean for the future of the internet in 2020 and beyond.
Fastly and Partners Form Bytecode Alliance
Fastly teams up with Mozilla, Intel, and Red Hat to form the Bytecode Alliance, an open-source community working together on WebAssembly-based compiler tools and foundations that work across many platforms.
Beta" A New Serverless Compute Environment
Fastly is now offering access to its serverless compute environment in private beta. Meet Compute@Edge, a uniquely secure, performant, and scalable approach to serverless computing.
The lifecycle and performance of a Lucet instance
Lucet, Fastly’s open source WebAssembly compiler and runtime system, is designed to take WebAssembly beyond the browser, and build a platform for faster, safer execution on Fastly’s edge cloud. This post will introduce each step in the Lucet lifecycle, and benchmark its performance to highlight how we keep overhead low.
Lucet Takes WebAssembly Beyond the Browser | Fastly
Today, we're thrilled to announce the open sourcing of Lucet, our native WebAssembly compiler and runtime. WebAssembly is a technology created to enable web browsers to safely execute programs at near-native speeds, and it's been shipping in the four major browsers since early 2017.
Guide for C and Rust programmers
Recently we launched Fastly Terrarium, a multi-language, browser-based editor and deployment platform where you can experiment with edge technology. Now, for those well-versed in C and Rust, we'll explore WebAssembly memory management and implementation.
Edge programming with Rust and WebAssembly
Take a developer deep dive into Terrarium, our multi-language, browser-based editor and deployment platform at the edge. Learn how to compile Rust programs to WebAssembly right on your local machine, interact with the Terrarium system, and explore some applications we’ve built with it.
How Terrarium reframes the compiler and sandbox relationship
Get hands-on with Terrarium, a Fastly project that lets developers harness the power of edge computing in the languages they already use. See how this technology demonstration came to be (and why we're even using that term), what problems it solves, and where it's headed.
How edge innovation sparked Fastly Labs
We’re thrilled to introduce Fastly Labs, a hub of in-progress projects and big ideas for the developer community to interact with, all built upon our philosophy of trust, transparency, and Fastly’s long history of edge innovation.
3 Key Takeaways from Altitude SF | Fastly
1.4 billion active monthly users, 10 billion requests per day, and 5.2 TB per second peak traffic — these are some of the staggering numbers we heard about at our 7th Altitude conference where customers, partners, and Fastlyans gathered to share experiences, exchange information and insights, and enjoy some tasty food and valuable networking. Here’s a few themes from the event worth highlighting.
Hijacking the control flow of a WebAssembly program
While WebAssembly has already proven a fertile attack surface for the browser, as more web application code moves to WebAssembly from Javascript there will be a need to research and secure WebAssembly programs themselves. The WebAssembly design obviates common classes of attacks that might be inherited from development languages like C and C++, but there is still some room for exploitation. This tutorial will cover control flow protection guarantees provided by WebAssembly, known weaknesses, and how to use clang control flow integrity (CFI) in WebAssembly programs to mitigate some risks around control flow hijacks.
