 a domain-specific language, and flexible application programming interfaces (“APIs”), we give customers comprehensive control over how their content is cached and how we respond to end-user requests. Our customers are able to make their own configuration changes versus waiting on a professional services engagement. This translates into faster end-user experiences and cost savings.

•DevOps-friendly. We have made it easy for our customers to integrate Fastly into their existing DevOps toolchains and workflows. We have enabled deep integration through rich APIs that let teams build with Terraform, or integrate with Amazon S3, Google Cloud Storage, Splunk, Drupal and many more popular platforms. Combined with our configurability and visibility, this empowered developers to make Fastly part of their continuous integration and continuous deployment (“CI/CD”) processes. As a result, our customers have been able to enhance end-user experiences by speeding up software and feature releases, without their CDN getting in the way. For example, we have seen customers release new code to production multiple times a day instead of once a month.

All of our product lines have been built on top of this single, programmable platform, and therefore they all benefit from the same granular control, real-time visibility, and immediate scalability.

As developers gained awareness of the power of our programmable platform, they have tapped into it to build complex performance-based use cases on top of it, from paywall authentication at the edge to A/B testing and edge redirects. From this trend, we realized that there was a need for a more general compute environment versus one that was primarily designed for caching and content delivery.

To address this need, we built a powerful compute environment on top of our programmable platform. We give customers access to our serverless compute environment through our compute offering, Fastly Compute. App developers can use this offering to build high performance, personalized apps on our programmable edge without the complexity of managing the underlying infrastructure. We knew our customers would need this environment to be scalable, fast and secure so we chose its building blocks carefully: 

•WebAssembly (“WASM”). We chose WASM, an extremely powerful open source technology that allows developers to run complex code on our platform. Apps can be compiled to WASM (using native machine code for better performance) and replicated to all our edge POPs. 

•Isolation technology. With security top of mind, we created a unique isolation technology. This gives us the ability to create and destroy an isolated sandbox for each user request that comes through, enabling code to be run in
