Products & Services

Programmable Edge Platform

Fastly’s programmable edge platform was built to support modern digital experiences.

We sit between our customers’ end users and their origin—whether that’s in the cloud, on premise or a hybrid environment—and power online experiences that are fast, safe, and engaging.

Fastly was founded in an era where legacy CDNs were failing to keep up with the explosive growth of user-generated content and demands for faster, more personalized websites and apps.

Legacy CDNs could not cache highly dynamic content at the edge—they had to continuously go back to origin to fetch this content, driving up egress costs.

Deploying changes meant, at best, hours-long waits for configurations to propagate.

At worst, it meant being forced to engage professional services at a cost of hundreds of dollars an hour.

Legacy CDNs also failed to provide real-time visibility.

Traffic logs were provided in batch format, meaning the data could be anywhere from 15 minutes to several hours old, making it impossible to monitor performance and get instant feedback.

With a view to addressing these challenges, we have taken a fundamentally different approach to architecting our platform.

• Powerful POPs.

We have architected our Points of Presence (“POPs”) using robust customized servers with incredible processing density.

As a result, our POPs require minimal footprint and yield colocation cost savings compared to traditional POP architectures.

We have located these POPs near major cloud providers and peered with Internet exchange points around the world, so that we can deliver content as close to end users as possible.

Because our POPs are powerful and well-connected to the Internet, we are able to operate fewer of them and still achieve optimal performance relative to traditional POPs.

• Software-defined network.

We have built a smarter network using fast switches and routing intelligence at the server layer.

This has allowed us to provide real-time responses by ensuring our customers’ traffic is routed in the most optimal manner on our network.

• Network Resilience .

Our network is built to withstand common performance degradation or connectivity issues with internet transit providers.

With fast path failover we automatically detect and re-route underperforming edge connections at the transport layer.

Precision Path detects underperforming origin connections and automatically reroutes the connection to the best alternative in real-time.

AutoPilot is an automated egress traffic engineering solution which enables us to reliably deliver high traffic events without manual intervention.

Fastly Platform

Fastly’s platform has evolved over the years to meet changing technology demands and the needs of a growing customer base.

Built on the core principles of performance, resilience, and programmability, it was originally designed to accelerate applications and services at global scale.

Over time, the platform expanded to also encompass edge computing, cloud-native architectures, unified application security, and emerging AI workloads.

Today, Fastly’s platform is designed to address the requirements of the always-on digital economy by providing essential infrastructure and application solutions for customers across a broad range of industries.

We serve organizations across ecommerce, streaming media, gaming, digital publishing, and high tech to financial services and more.

Our platform supports diverse use cases, from edge distribution and delivery, to cloud-native applications, serverless development, web application and API protection, and edge computing.

A Modern Platform

We have taken advantage of modern network design to build a platform optimized for performance, resilience and scale.

Our platform is built to accelerate a wide range of content, including dynamic content, allowing customers to deliver faster, more personalized web and mobile experiences.

It is also designed to scale rapidly and intelligently, while being resilient, to reliably support peak traffic events like live streaming events, flash sales, and major gaming releases.

As cloud-native solutions have become more mainstream for building and running applications, we are also well suited to support these environments.

We offer an API-driven, developer-friendly platform that integrates smoothly with modern stacks, continuous integration/continuous deployment pipelines and cloud infrastructures.

Our platform acts as an intelligent edge layer in front of customers’ single or multi-cloud environments.

By accelerating, protecting, and optimizing API traffic, intelligently routing requests, and reducing load on origin servers, we improve application performance, security, and reliability.

These benefits extend beyond enhancing centralized cloud applications to also supporting larger deployments in virtual private clouds and globally distributed, edge-native applications.

Edge Computing

As application architectures have evolved, with latency-sensitive functionality moving closer to end users, we have expanded our platform to support programmable edge computing.

Built on WebAssembly (“WASM”) to support microsecond code execution times, our compute environment enables customers to run layers of intelligent logic, including AI, in front of their applications and services, all while maintaining performance.

This allows customers to optimize their workflows for higher conversion rates, increased revenue generation, and faster developer innovation.

With built-in isolation technology, the platform is also secure by design, enabling customers to run business-critical workloads while minimizing the potential for vulnerabilities or unauthorized access.

Some common edge compute use cases include fast, scalable personalization;

security and authentication enforcement;

and on-the-fly image or video optimization.

Being part of core application workflows, these compute use cases can drive even deeper usage of Fastly’s platform.

Unified Application Security

In response to growing customer demand for consolidated application security, we offer a suite of security solutions to minimize the impact of attacks on and abuse against applications, APIs, and software services.

By design, our powerful platform is ideally suited to adapt to and sustain resilience against massive traffic swells, whether network-layer DDoS attacks or global-scale real-time media events.

Our AI-driven Adaptive Threat Engine enables real-time detection and mitigation of evolving attacks through traffic pattern analysis across our network, which we also apply to our customers’ individual services through our DDoS Protection product.

We layer software products on top of our resilient platform, empowering customers with tailorable protection that lets them block, deceive, redirect, and otherwise manage attack, abuse, and other unwanted traffic.

Our integrated web application firewall and bot management capabilities leverage our platform’s evidence-based, context-aware detection capabilities so customers can proactively address unwanted activity.

Our platform provides real-time visibility into security events, attack traffic, and rule performance, enabling faster identification and remediation of potential risks to minimize the business impact of security incidents.

Our built-in deception and mitigation techniques allow customers to detect and block attack attempts while obfuscating successful defense from attackers, slowing down attackers’ ability to evolve their operations.

As AI becomes an essential part of modern applications, we are pursuing a dual opportunity:

enabling AI workloads for our customers and leveraging AI to enhance our platform’s usability and capabilities.

Our platform offers semantic caching and edge data stores to speed up AI workloads, while support for real-time messaging and pre-processing of visual data for AI models reduces latency and improves efficiency for AI applications.

Fastly’s platform also includes capabilities for managing agentic AI and AI bot traffic, and controlling services through natural language interfaces.

Platform Differentiators

The evolution of Fastly’s platform is powered by a set of core differentiators.

These differentiators have allowed us to rapidly adapt to changing market needs.

Robust architecture:

Our network is comprised of robust, high-density POPs (points of presence) designed to minimize footprint and colocation costs while delivering content closer to end users.

Strategically located near major cloud providers and peered with Internet exchanges worldwide, our POPs are designed to achieve optimal performance with fewer nodes than traditional architectures.

Software-controlled:

We built a smarter network using fast switches and server-layer routing intelligence, allowing us to deliver real-time responses by optimally routing customer traffic.

Our network also supports origin health checks for CDN and Compute services, which are designed to monitor and direct traffic away from unhealthy backends to maintain service reliability.

Resilient by design:

Our network is designed to withstand common performance degradation and connectivity issues with internet transit providers.

Fast Path Failover provides automatic detection and rerouting of underperforming edge connections at the transport layer.

Precision Path monitors origin connections and reroutes traffic in real time to the best available path.

Autopilot, our automated egress traffic engineering solution, allows us to reliably manage high-traffic events without manual intervention.

When it comes to protecting against DDoS attacks, our Adaptive Threat Engine is designed to enhance platform resilience by automatically detecting and mitigating attacks in real time, using advanced behavior modeling and traffic analysis to stop threats even when attackers rotate IPs.

Fully programmable:

In keeping with our belief that companies should be able to control everything through software, we have built a fully programmable platform.

Using Varnish Configuration Language (“VCL”) as 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 versu s waiting on a professional services engagement.

This translates into faster end-user experiences and cost savings.

We have built a fully programmable platform that gives customers comprehensive control over how their content is cached and how it responds to end-user requests.

Using our flexible APIs, customers can make configuration changes themselves, rather than relying on professional services.

This results in faster end-user experiences and cost savings for our customers, while unlocking developer innovation.

Granular visibility:

Customers need continuous insight into the status of their apps and services.

Across our product lines, we provide real-time logging, rich metrics, alerts and dashboards enabling faster, data-driven decision making.

Software engineers can monitor performance, detect anomalies, and troubleshoot issues faster using these tools, maximizing availability and performance for their apps and services.

Fastly’s granular visibility enables customers to iterate quickly on new releases, bringing innovations to market faster so they can stay ahead of competitors.

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 a safe, fast execution environment at scale.

• WASM compiler and runtime.

To make this code run even faster, we built our own WASM compiler and runtime.

Through our observability offerings, we also provide real-time insights to inform continuous performance improvements and facilitate faster debugging during development.

See “ Compute” and “Observability” secti ons below for more details.

We make it easy for customers to integrate Fastly into their DevOps workflows through rich APIs and support for platforms like Terraform, Amazon S3, and Google Cloud Storage.

Combined with our configurability and visibility, these integrations enable developers to include Fastly in their continuous integration and deployment processes, accelerating and optimizing software and feature releases to enable their business goals.

Powerful Compute environment:

Our platform provides a serverless compute environment that enables developers to run business-critical workloads at the edge with high performance, resilience, and minimal maintenance.

Using WASM, code compiles to native machine code and executes in secure, isolated sandboxes across all our edge service delivery points.

Our compute environment enables enterprises to deliver low-latency, reliable, and secure workloads and applications that serve business-critical use cases spanning new revenue opportunities, differentiation, and AI innovation.
