Global Availability

The Edge Delivery Services architecture for Adobe Experience Manager makes use of redundant content delivery networks (CDNs) to ensure high availability with low latency. The cacheable components of your sites are delivered directly from globally-distributed points of presence (POPs).

Your sites, globally available

The two highest priorities in delivering web experiences are availability and performance. For this reason, we use multiple content delivery networks to provide the Adobe Experience Manager service. Multiple CDNs so that, in the rare case of a CDN outage, we can switch the full delivery stack to a separate CDN to provide continued high availability.

Each CDN uses dozens to thousands of different points of presence (POPs): high-performance caching servers located at critical internet junctures in global locations, close to population centers. These POPs cache the content served for your websites and make it available to “nearby” visitors, minimizing the inherent network latency of interactions.

Operational Telemetry is used to maintain awareness of site stability and availability over time.

Your content, globally distributed

In order to ensure this global availability, your cacheable content has to be globally distributed to the same extent that it is published to global visitors. Each of the core storage areas of the AEM content hub (media, content, code) is therefore equally globally-distributed to be within reach of those global visitors.

What about data residency?

The Edge Delivery Services architecture is designed for global publication of information that would normally appear on public sites. Site owners are responsible for ensuring that the information they choose to publish is in compliance with applicable laws or regulations. Likewise, the data we collect for Operational Telemetry is deliberately limited for the sake of privacy and compliance.
