Overview of AEM Offerings
Adobe Experience Manager now encompasses three distinct offerings, often confused due to overlapping names and shared functionality:
- AEM 6.5 LTS (Long-Term Support)
- AEM as a Cloud Service (AEMaaCS)
- Edge Delivery Services
Each serves different use cases and has its own technical profile, support roadmap, and licensing structure.
AEM 6.5 LTS
AEM 6.5 LTS is the self-hosted version of AEM, closely resembling the original architecture. It allows for various deployment options, including self-hosting or Adobe-managed hosting. Key points include:
-
Customization: Highly customizable and has been receiving continuous service packs since its release in 2019.
-
Long-Term Support: Adobe has committed to supporting AEM 6.5 LTS for the foreseeable future, addressing concerns about its potential end-of-life status.
-
Technical Specifications: Runs on JDK 17, ensuring compatibility with future updates.
AEM as a Cloud Service
Launched in 2020, AEM as a Cloud Service is designed to leverage cloud capabilities. It shares many features with AEM 6.5 but includes:
- Built-in CDN: Offers a content delivery network that enhances performance.
- Scalability: Designed to auto-scale, although there are limits to its performance capabilities.
- Subscription Model: Operates on a subscription basis, with no perpetual licensing options available.

Edge Delivery Services
Edge Delivery Services, previously known as Project Helix, is a separate offering that focuses on document-based content management. Key features include:
- Simplicity: Designed to be simpler and faster to develop on compared to traditional AEM.
- Integration: Can be integrated with AEM Cloud Service, allowing for a hybrid approach.
- Unique Architecture: Operates independently from AEM, which means different skills and techniques are required for customization.
Advantages and Challenges
AEM 6.5 LTS
Advantages:
- Flexibility and customization capabilities.
- Long-term support ensures stability for entrenched customers.
Challenges:
- Requires a significant investment in skilled personnel.
- Performance optimization can be complex and resource-intensive.
AEM as a Cloud Service
Advantages:
- Autoscaling capabilities can handle varying traffic loads.
- Simplifies CI/CD pipeline management.
Challenges:
- Migration from AEM 6.5 to Cloud Service can be complex and time-consuming.
- Performance may not always meet expectations, requiring ongoing monitoring and optimization.
Edge Delivery Services
Advantages:
- Fast development cycles and reduced labor costs.
- Easy integration with existing AEM services for enhanced functionality.
Challenges:
- Limited templating and component policies can hinder strict content governance.
- Still maturing in terms of features and documentation, which can lead to implementation challenges.
Licensing Considerations
Licensing models vary significantly across the three offerings:
-
AEM 6.5 LTS: Offers both perpetual and subscription-based licenses.
-
AEM as a Cloud Service and Edge Delivery: Operate on a consumption-based licensing model, which can be a shift for organizations used to traditional licensing.
Migration and Implementation Strategies
During the meetup, attendees discussed various scenarios for migrating to these platforms:
- Organizations currently using AEM 6.5 LTS should evaluate their specific needs and consider the long-term implications of moving to Cloud Service or Edge Delivery.
- For new implementations, Edge Delivery may offer a faster and more cost-effective solution, especially for content-heavy sites.
Conclusion
The AEM Columbus User Group meetup provided valuable insights into the current state of Adobe Experience Manager offerings. Understanding the differences between AEM 6.5 LTS, AEM as a Cloud Service, and Edge Delivery Services is crucial for organizations looking to optimize their content management strategies. As Adobe continues to evolve its products, staying informed about these changes will help users make better decisions for their digital experiences.
