Fastly’s Full-Site Delivery services

  Last updated October 12, 2018

Fastly’s Full-Site Delivery services allow you to speed up websites and mobile applications by pushing content closer to users, providing improved and secure experiences across the world. Full-Site Delivery services include the following features.

Content serving, caching, and control

Full-Site Delivery services use Fastly’s global content delivery capabilities to cache and accelerate delivery of your HTTP-based file content such as video, images, CSS, Javascript files, as well as HTML and API responses. Specifically:

Edge logic and advanced content delivery control

Fastly’s content delivery capabilities are based on a heavily extended version of the Varnish caching software. Varnish software gives you direct access to content delivery, control and edge logic capabilities, via the expressive HTTP inspection and modification scripting language, Varnish Configuration Language (VCL).

Streaming content delivery

Fastly’s Streaming Delivery services allows you to stream live and video-on-demand streaming content by leveraging Fastly’s native support of common streaming formats. Fastly streaming format support includes HTTP Live Streaming (HLS), HTTP Dynamic Streaming (HDS), Dynamic Adaptive Streaming over HTTP (MPEG-DASH) and HTTP Smooth Streaming.

Origin shielding

You can designate a Fastly point of presence (POP) to serve as a shield for your origin servers, thus enabling increased cache hit rates for your Fastly services and potentially protecting your origin servers from unexpected spikes in requests for content. You can optimize this shielding geographically by configuring different shield POPs for different origin server locations. Origin shielding is not enabled by default. To use it, you must specifically enable it.

Load balancing

Services configured with multiple origin servers will automatically distribute requests to those servers evenly. You can modify this default load balancing behavior with a variety of conditions and load balancing rules.

Health checks

The health of your origin servers can be monitored with configurable health checks to help ensure only responsive origin servers are being sent requests.

Fastly web interface

All Fastly accounts have access to Fastly's web interface, allowing it to be managed by multiple users within your organization. You can control each user's role, as well as control the scope of their service access and their specific permission levels. Fastly services can be created, monitored, and managed through the Fastly Web Interface via any standard, modern web browser.

Application programming interface (API)

Fastly provides an application programming interface (API), accessible via HTTPS, through which Fastly services can be created and configured, and customers can access account information and analytics.

Real-time log streaming

To help you tune the performance of your Fastly services, we support real-time log streaming to a variety of locations, including third-party services, for storage and analysis. You can find our supported logging endpoints in our list of streaming log guides. We limit real-time log usage to a monthly average of one log statement per request, per service.

Transport Layer Security

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. All Fastly services have access to our free shared domain option, plus a variety of additional paid TLS services to meet your TLS business and technical needs.

Always-on DDoS mitigation

Fastly's globally distributed network was built to absorb Distributed Denial of Service (DDoS) attacks. As part of Fastly's standard, Full Site Delivery services, all customers receive access to a combination of features inherent in Fastly Edge Cloud network capabilities that help protect the availability of your content from DDoS threats.

Pricing and billing

Full-Site Delivery prices are based on the volume of content delivered to your end users and the location of the POPs from which that content was served. Fastly billing is done in arrears based on actual usage with month-to-date usage being available via both our web interface and APIs.
