• 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

12#evolverocks

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)

13#evolverocks

GLOBALIZATION• 2 Level Structure

• EN is master

• Language (eg French) – followed by Locale

• Content Translation with SDL World Server

• Custom Integration

30#evolverocks

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

31#evolverocks

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

32#evolverocks

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
