The user connects to the customizable Edge Services endpoint (with its SSL/TLS certificate), which fetches content from the Edge Services cache, which itself fetches content to cache from an origin which is either an Object Storage bucket or Load Balancer.

-An Edge Services pipeline consists of an [origin](#origin), which Edge Services can protect from threats with a [Web Application Firewall](#web-application-firewall), and for which it also requests and [caches](#cache) content. Each pipeline also has an [endpoint](#endpoint) from which content is accessed served via Edge Services. The pipeline's endpoint can be customized with a user-defined [subdomain](/domains-and-dns/concepts/#subdomain) and associated [certificate](#certificate) so that Edge Services can serve content over HTTPS.

 You can create an Edge Services pipeline for each of your Object Storage buckets or Load Balancer origins. Note that caching and WAF can be enabled and disabled at will, so are optional parts of the pipeline, as is the customization of the endpoint. WAF is only available for Load Balancer origins, not Object Storage buckets.
