Learn to build on the Fastly platform

Service types

Fastly offers two types of edge service: highly performant and configurable services powered by Fastly VCL, and next generation Wasm-powered compute@edge services currently in private beta:

• Learn about using VCL
• Sign up to the compute@edge beta program

Domains and origins

Domains are web addresses that point to your services on Fastly. Origins are web addresses that point to the servers hosting your application.

• Managing domains
• Managing origins
• Working with health checks

HTTP and caching

Fastly respects the instructions you provide via HTTP headers such as Cache-Control. But you can also exert much finer-grained control over the way we load and cache your resources.

• Controlling how Fastly caches your resources
• Deciphering cache hit and miss headers for shielded services
• Purging
• Shielding
• Clustering
• Request collapsing
• Segmented Caching
• HTTP/2 server push
• Protected headers

Content delivery and transformation

As well as serving content loaded from your origin, Fastly can also manipulate that content in useful ways, or even generate content from scratch without loading anything from your origin.

• Compressing responses with GZip
• Optimizing images
• On-the-Fly Packaging video manifests

Data storage

Fastly provides key-value stores at the edge that are highly optimized for reads.

• Edge Dictionaries

Security

Learn how to configure Fastly to meet your security needs.

• Fastly IP ranges
