Fastly Expands Serverless Capabilities With the Launch of Compute@Edge

November 6, 2019

The new product, in beta, offers developers robust edge compute technology, instant global scale, and the ability to run logic on Fastly’s Edge Cloud Platform.

SAN FRANCISCO--(BUSINESS WIRE)-- Fastly, Inc. (NYSE: FSLY), provider of an edge cloud platform, today announces the beta launch of Compute@Edge, a powerful new language-agnostic compute environment. The major milestone marks an evolution of Fastly’s edge computing capabilities and the company’s innovation in the serverless space. Fastly’s Compute@Edge is designed to empower developers to build far more advanced edge applications with greater security, more robust logic, and new levels of performance.

Developers are being empowered to create new and improved digital experiences with their own technology choices around the cloud platforms, services, and programming languages needed. Rather than spend time on operational overhead, their goal is to continue to reinvent the way end users live, work, and play on the web. Fastly's Compute@Edge gives developers the freedom to push complex logic closer to end users, and reduces the time to innovate by allowing developers to focus on strategy that drives their companies forward.

Fastly Compute@Edge Leverages Speed for Global Scale and Security

At 35.4 microseconds, Fastly’s Compute@Edge environment offers a 100x faster startup time than any other solution on the market. Benefits of Compute@Edge, powered by Fastly’s WebAssembly compiler and runtime, include:

  • Instant scale, around the globe: Code is run around the world instead of a single region. This allows developers to reduce code execution latency and further optimize the performance of their code — without worrying about managing the underlying infrastructure.
  • Improved security posture: The unmatched speed at which the environment operates, combined with Fastly’s isolated sandboxing technology, reduces the risk of accidental data leakage. With a “burn-after-reading” approach to request memory, entire classes of vulnerabilities are eliminated.
  • Serverless compute environment: Fastly added tooling to support Rust as the second language – in addition to Varnish Configuration Language (VCL) – for Compute@Edge, due to its growing popularity in innovative, forward-thinking organizations. More languages will be added in the future.

“As DevOps takes root in enterprises, there's a growing push to empower developers with the capabilities they need to create and run applications in a broader range of compute environments,” said Craig Matsumoto, Senior Analyst at 451 Research. “This includes the option of tapping into computing power outside centralized clouds, often for performance or security reasons. Fastly's Compute@Edge is positioned as this type of environment for executing logic at the edge.”

Fastly has operated in the serverless market since its founding in 2011 through its Edge Cloud Platform, including products like Full Site Delivery, Load Balancer, DDoS, and Web Application Firewall (WAF). To date, Fastly’s serverless computing offering has focused on delivery-centric use cases via its VCL-powered programmable edge. With the introduction of Compute@Edge, Fastly unlocks even more powerful and widely-applicable computing capabilities.

“When we started Fastly, we sought to build a platform with the power to realize the future of edge computing — from our software-defined modern network to our point of presence design, everything has led us to this point,” explained Tyler McMullen, CTO of Fastly. “With this launch, we’re excited to double down on that vision and work with enterprises to help them build truly complete applications in an environment that offers new levels of stability, security, and global scale.”
