• Finite number of Instances – with Governance• New instance should be created only when:
– Independent branding and experience – Independent Dev teams and stakeholders – with
totally different integrations – Totally different operational SLAs required– Example Symantec/Norton

Migration Strategy
• Technologies before AEM: Teamsite, Drupal• AEM adopted three years ago• Major web presence on AEM
– Long tail of migrations continue to this day• Two options for migrations
– Assisted Migrations (scripted, automated)– User driven (new platform for new content + retire older content)

AEM Architecture Anti Patterns• Over Customization • Everything is a nail – when AEM is the hammer
• AEM as a Façade • AEM as THE Application Engine
• Taking every “sold” feature on its face value• AEM – Target integration
• Continuing to use AEM classic UI over touch• Not planning for continued investment in AEM (and other Adobe)
Products & resources• Includes investment in a tight well organized team• Investment of time in building a good relationship in Adobe & community

AEM in the cloud• Most installations so far are on prem – or not completely cloud native.• Future – looks different – more and more push to Cloud.• Multiple options going forward
• AEM Managed Services (AWS MarketPlace)• Azure Virtual Machine (BYOL) – on windows• Rackspace – complete with full suggested deployment architectures
• Need Adobe Product to evolve more also:• More Cloud Native offerings• Support for MicroServices & Continuous Integration& Delivery• Better Support for Multi Tenancy in same instance
© 2016 Adobe Systems Incorporated. All Rights Reserved. Adobe Confidential. 32
Wishlist from Adobe• Improved Integrations – eg: Target, Segments (Audience Mgr),
eCommerce• Better Support and penetration in Cloud
• More Cloud Native offerings• Support for MicroServices & Continuous Integration& Delivery• Better Support for Multi Tenancy in same instance
• More robust and scalable repository • Improved support for Active Passive Mode, Backups, Maintenance activities• Improved content transfer capability from Prod to Non-Prod
