How Compute is tackling the most frustrating aspects of serverless
MJ Jones
Serverless solutions are good news for developers, but they can cause plenty of headaches, including cold starts, regional latency, and a lack of observability. Compute, Fastly’s serverless compute environment — built on Wasm and run globally — can help solve those problems.

Why “by developers, for developers” matters
Joshua Bixby
Developer-centricity is now a mission-critical philosophy for companies to embrace. And during COVID-19, we all know that the stakes have never been higher. We’ve seen that businesses that operate with a dev-first mindset at their core will have the strategic advantage and will only increase it, today and into the future.

Fastly’s security DNA: a look at our culture of safety, privacy, and trust
Dana Wolf
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
Peter Bourgon
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
Sean Leach
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.

The lifecycle and performance of a Lucet instance
Adam Foltzer
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.

3 Key Takeaways from Altitude SF | Fastly
Courtney Nash
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
Jonathan Foote
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.
