Real-time visibility

Real-time logs, streamed from our edge, give near-instant visibility into traffic trends, performance, potential problems, and threats.

Insights you can use

Logs provide an important resource for troubleshooting connectivity problems, pinpointing configuration areas that could use performance tuning, and identifying the causes of service disruptions.

Logging provider integrations

Instantly stream your log files to a logging provider of your choosing, and dig into any aspect of a request or response to diagnose problems and understand how your customers are engaging with your app.

Support for agile DevOps

The days of agile development efforts getting stuck in release queues are over. With our real-time visibility and control we integrate into your existing workflows so you can deploy new software or feature enhancements weekly, daily, or even multiple times a day.

Fastly’s fully configurable CDN enables you to change content quickly, even event-driven content. Easily adjust your configuration settings via an API and roll back changes as needed without having to reach out to Professional Services.

Rapid content changes

We give you fine-grained control over how your content is cached. Create your own custom caching rules, upload them to our POPs and activate/deactivate them on the fly. 

API-friendly control

Our full-featured API makes it easy to change your configuration settings. Instantly purge stale content, reset Time-to-Live for content, clear cache or turn on new features — all through an API call.

Stress-free rollbacks

Fastly locks versions of services you've already activated to make rollbacks safer and provide version control.

Benefits

One modern network

Our secure, scalable global network is built smarter. We use strategically distributed, highly performant POPs to help you move data and applications closer to users and deliver up-to-date content quickly. Our network is  built to support the most demanding streaming needs.

Safety in depth

Our DDoS, next-gen WAF and TLS offerings provide organizations protection and control, without sacrificing performance and velocity. We have built security into the fabric of our platform, alongside performance, providing developers and security operations teams with a fast, safe environment to create, build, and run modern applications.

Savings and efficiencies

By caching more at the edge and minimizing trips to origin, Deliver@Edge can help reduce both infrastructure and egress costs. Plus, you’ll operate more efficiently by making configuration changes on the fly. Changes automatically pass from development to production and there’s no need to contact Professional Services.

Fully configurable

Built API first, all Deliver@Edge products work seamlessly with your technology stack. We support out-of-the-box integration with common CI/CD toolchains, config management tools and code repo systems. Get fine-grained control over how your content is cached. Instantly purge stale content, reset Times to Live (TTL) or turn on new features — all through an API call.

Real-time visibility and control

What if you could spot performance and security issues in time to do something about them? With real-time logs and full control over your configuration, you can spot issues and push config and security rule changes in seconds. That’s right, we said seconds.

Fastly's Modern CDN Key features

Configurability
API configurability and Fastly web interface with usage graphs/maps

The API is organized into collections of endpoints that allow manipulation of objects related to Fastly services and accounts.

Dedicated IPs

Can be used to support TLS certificate management for non-SNI clients, to support custom cipher suites or IP-to-service pinning, or to help manage zero-rated billing endpoints.

Dynamic ad insertion preparation

Fastly allows you embed custom metadata or ad markers about a stream into video segments at specified time instances.

Dynamic site acceleration

Fastly’s dynamic site acceleration comes standard for speedy content delivery that makes a positive impact on conversion and retention rates, SEO, and ad revenue.

Edge logic and advanced content delivery control

Deliver@Edge gives you direct access to content delivery, control and edge logic capabilities.

Full control of HTTP headers

Fastly gives you complete control over HTTP headers so you can determine how you want your content served, including the ability to send one set of instructions to your Fastly services and another set of instructions to downstream caches, proxies or browsers.

Static, dynamic and video content delivery

Fastly does not charge separately for web vs. streaming content nor for features like instant purging that make supporting dynamic and event-driven content possible. We provide one programmable service that optimizes all types of HTTP content.

Supplier Provided Prefix (BYOIP)

Allows you to have your IP spaces announced, routed, and served by Fastly infrastructure for use with production services.

Time to Live (TTL) controls

Content expiration is controlled via Time to Live (TTL) settings you configure that work as timers on your cached content.

Real-time control
Instant purge

Remove your cached content worldwide on demand, within milliseconds, when your dynamic or event-driven content changes.

Real-time log streaming

To help you tune the performance of your Fastly services, we support real-time log streaming of data that passes through Fastly.

Soft purge

Allows you to mark content as outdated (stale) instead of permanently purging and thereby deleting it from Fastly's caches.

Surrogate key purging

A surrogate key allows you to selectively purge related content.

Safety
Always-on DDoS mitigation

Fastly's globally distributed network was built to absorb Distributed Denial of Service (DDoS) attacks.

Auto-healing

Fastly can automatically detect and, in real time, route around transient connection problems that occur when fetching content from your origin servers or when delivering content to end users from Fastly's edge cloud.

Content protection

Fastly can encrypt videos packaged into HLS and MPEG-DASH and supports multiple Digital Rights Management (DRM) technologies.

Grace mode

Grace mode shields application servers by instructing Deliver@Edge to continue to serve stale or expired (but likely still valid) content to end users for a set amount of time.

Transport Layer Security (TLS)

Fastly supports a variety of Transport Layer Security (TLS) services that allow websites and applications to serve traffic over HTTP Secure (HTTPS), providing added privacy and data security for your services and end users.

Scalability
Caching

Fastly caches your content close to end users throughout the world so it can be served more quickly and reduce load and cost of your origin services

Content compression

Fastly can compress your content in real-time at the edge, providing snappier end user experiences and off loading content compression from your origin services.

Origin shielding

You can designate a Fastly point of presence (POP) to serve as a shield for your origin servers, enabling increased cache hit rates for your Fastly services and potentially protecting your origin servers from unexpected spikes in requests.

Request collapsing

Fastly's request collapsing feature groups those requests and fulfills them together when it receives the refreshed content from your origin.

Support plans

Fastly offers several support plans to meet your needs: standard, gold and enterprise.

Standard

Free of charge and available as soon as you sign up with Fastly.

Gold

Proactive alerts for high-impact events, expedited 24/7 incident response times, and a 100% uptime Service Level Agreement (SLA) guarantee.
