What is difference between Journey Orchestration and Journey Optimizer ?

Hey @an1-3 

Adobe Journey Optimizer (AJO): (add-on product)

Adobe Journey Optimizer is an agile and scalable application for creating and delivering personalized, connected, and timely customer experiences across any app, device, or channel.

Adobe Journey Optimizer’s key capabilities include:

1. Real-time customer insights and engagement – An integrated profile fuses live data from all sources
   across customer touchpoints, including behavioral, transactional, financial, and operational data to optimize personal and contextual experiences for customers in their time.
2. Modern omnichannel orchestration and execution – A single canvas on which to harmonize and optimize the
   customer journey for 1:1 customer engagement and marketing outreach—to help brands deliver more value across the customer lifecycle. Customer journeys designed in Journey Optimizer can be dynamic and event based to help brands react to real-time signals as well as connect those interactions with scheduled campaigns so the right decisions can be made about what communications to send a customer, when and through what channels.
3. Intelligent decisioning and personalization– Brands can apply centralized decisioning and incorporate artificial intelligence and machine learning to surface predictive insights throughout the customer experience, making it easier to automate decisions and optimize the experience at scale.
