ACCS Learning Series – Part 3: Rethinking Commerce Customizations with Adobe App Builder

🚀 ACCS Learning Series – Part 3: Rethinking Commerce Customizations with Adobe App Builder
As I continued exploring Adobe Commerce as a Cloud Service (ACCS), one architectural principle stood out to me:
Not every business capability belongs inside the Commerce application.
For many years, extending Commerce often meant adding modules, plugins, observers, or scheduled jobs directly into the application. While this approach solved business needs, it also increased coupling between customizations and the core platform, making upgrades and long-term maintenance more challenging.
One of the most valuable ideas introduced by ACCS is shifting custom business capabilities outside the Commerce core whenever possible.
This changes the way we think about solution design.
Instead of asking:
"Where should I customize Commerce?"
We start asking:
"Does this capability really belong inside Commerce?"
That simple shift encourages solutions that are more modular, independently deployable, and easier to evolve over time.
From an architectural perspective, this brings several advantages:
• Clear separation of responsibilities
• Faster delivery of business capabilities
• Independent release cycles
• Better scalability for integrations
• Reduced dependency on Commerce deployments
It also reinforces an important design principle:
Keep the Commerce platform focused on commerce, while allowing surrounding business capabilities to evolve independently.
The attached diagrams summarize the App Builder architecture and provide a simple decision framework for choosing the right extensibility option based on the business requirement.
My biggest takeaway this week:
Great architecture isn't defined by how much custom code we write—it's defined by placing the right capability in the right layer.
Next in the series, I'll be exploring API Mesh and how it simplifies API orchestration, aggregation, and secure integration across multiple backend services.
Stay tuned. 🚀
