The next-generation Adobe Target SDKs now offer on-device decisioning, which provides the ability to cache your A/B and Experience Targeting (XT) campaigns on your server and perform in-memory decisioning at near-zero latency, without blocking network requests to Adobe Target’s Edge Network.
Adobe Target also offers the flexibility of delivering the most relevant and up-to-date experience from your experimentation and ML-driven personalization campaigns via a live server call. In other words, when performance is most important, you can choose to utilize on-device decisioning, but when the most relevant and up-to-date experience is needed, a server call can be made instead. See when to use on-device vs. edge decisioning to learn about use cases that warrant using one over the other.
On-device decisioning is available for both client-side as well as server-side implementations. This article describes on-device decisioning for server-side. For information regarding on-device decisioning for client-side, reference the client-side implementation documentation here.
When you install and initialize an Adobe Target SDK with on-device decisioning enabled, a rule artifact is downloaded and cached locally on your server, from the Akamai CDN closest to your server. When a request to retrieve an Adobe Target experience is made within your server-side application, the decision regarding which content to return is made in-memory, based on the metadata encoded in the cached rule artifact, which defines all of your on-device decisioning A/B and XT activities.

On-device decisioning supports the following activity types created by the Form-based Experience Composer:
On-device decisioning supports the following allocation method:
On-device decisioning supports the following audience rules:
|Audience Rule||On-device Decisioning|
When using on-device decisioning, the following geo attributes are supported:
|Experience Cloud Audiences (Audiences from Adobe Audience Manager, Adobe Analytics, and Adobe Experience Manager||No|
On-device decisioning is available for all Adobe Target customers who use Adobe Target server-side SDKs. In order to enable this feature, navigate to Administration > Implementation > Account details in the Adobe Target UI, and enable the On-Device Decisioning toggle.
You must have the Admin or Approver user role to enable or disable the On-Device Decisioning toggle.
After enabling the On-Device Decisioning toggle, Adobe Target will begin generating and propagating rule artifacts for your client.
Ensure you enable the toggle before you initialize the Adobe Target SDK to use on-device decisioning. The rule artifacts will first need to generate and propagate to the Akamai CDNs in order for on-device decisioning to work.
Toggle this on when you would like all your live Target activities that qualify for on-device decisioning to be automatically included in the artifact.
Leaving this toggle off means you will need to re-create and activate any on-device decisioning activities in order for them to be included in the generated rules artifact.
After you create an activity, a label called Decisioning Method, visible in the activity detail page, indicates whether the activity is on-device decisioning capable.
You can also see all activities that are on-device decisioning capable on the Activities page by adding the column Decisioning Method to the list of activities.
After creating and activating an activity that is on-device decisioning capable, it may take up 5-10 minutes before it is included in the rules artifact that is generated and propagated to the Akamai CDN PoPs.

More than ever, marketers, product owners and developers are being tasked with optimizing the overall customer experience on sites, in apps, and everywhere else they connect with their customers. Multiple tools with data silos and complicated implementations are inadequate.
In this recorded webinar, Adobe Target product experts discuss how moving critical experience optimization decisions on-device to execute locally with near-zero latency can open doors to exciting new use cases while improving site performance for your customers.
