AEM Sites, Assets, and Forms as Three Separate Products
Adobe Experience Manager isn't one CMS - it's a federation of AEM Sites, AEM Assets, and AEM Forms, each with its own licensing, learning curve, and integration logic. The unified DXP positioning is real on paper; in practice, teams manage three connected products with separate operational concerns.
Java, OSGi, Sling, and JCR Stack Burden
AEM's technology foundation - Apache Sling, OSGi, Java Content Repository (JCR) on Apache Jackrabbit Oak, AEM Dispatcher caching, Touch UI - requires specialized infrastructure and specialized people. Hiring senior AEM developers is increasingly difficult as the JavaScript and modern CMS ecosystems pull talent elsewhere.
Implementation Cost That Reaches Eight Figures
AEM Sites implementations regularly run 18 to 36 months for large enterprise deployments, with implementation partner fees ranging from $1M to $10M+. Even AEM Cloud Service (Adobe's managed version) reduces infrastructure work but doesn't reduce the implementation and customization burden.
Adobe Experience Cloud Lock-In
AEM's deepest integrations are with Adobe Target (personalization), Adobe Analytics, Adobe Campaign, and Adobe Workfront. Getting full value requires the broader Adobe Experience Cloud stack - and the licensing for that stack compounds quickly. Decoupling from Adobe becomes harder every year.
Edge Delivery Services Doesn't Eliminate the AEM Stack
Adobe's Edge Delivery Services (formerly Helix or Project Franklin) provides modern front-end delivery, but it sits alongside AEM rather than replacing it. Teams adopting Edge Delivery still maintain AEM author instances, AEM Cloud Service licensing, and the underlying Java/OSGi stack - adding to total cost rather than reducing it.
The Real Cost: $1M+ Per Year for a Platform Marketing Doesn't Touch Directly
Adobe Experience Manager Sites licensing typically starts in the high six figures annually for enterprise deployments and regularly clears $1M for large multi-brand or multi-region implementations. Add AEM Assets, AEM Forms, Adobe Target, Adobe Analytics, Adobe Campaign, AEM Cloud Service infrastructure, certified Adobe partner implementation, and dedicated Java/AEM developer salaries. Total annual spend regularly exceeds $5M for large enterprises. HubSpot Enterprise typically delivers comparable marketing capability at a fraction of that cost - with operations marketers can actually own.
