Cisco uses Adobe Experience Manager (AEM) to power their digital presence including cisco.com. To meet Cisco's requirements for high availability, performance, and scalability, AEM was implemented across multiple datacenters in an active-active configuration. Caching is a key part of the architecture, with caching at multiple levels including the browser, Akamai CDN, Apache, and Dispatcher. The architecture also supports features such as content transformation, multi-tenancy, and incremental content refreshes.
