Best Practices for Hosting an eCommerce App on monday.com: Which Architecture Works?

Hi everyone
I’m working on an eCommerce application and planning to integrate it with monday.com (via boards, automations, dashboards, etc.). I’d love to hear how others have approached the hosting and architecture side of things when integrating an external eCommerce app with monday.com.
Here are a few specific questions:

Do you host the eCommerce backend separately (e.g., on AWS/DigitalOcean) and connect it via monday.com’s API or use monday.com as the primary platform?

What’s your setup for data syncing between the eCommerce system and monday.com boards (products, orders, customers)?

Which monday.com features (automations, webhooks, integrations) did you rely on to keep things in sync and avoid duplication?

How did you handle scalability and performance when your store grew – did you change your architecture or the way you used monday.com?

Any tips for keeping the system secure (especially when dealing with customer data, payments, and external integrations) while still leveraging monday.com’s dashboards and workflows?

I’m planning to build a clean, maintainable architecture and want to learn from real-world implementations before diving into it. Appreciate any insights, links to use cases, or lessons learned you’ve got!
Thanks a lot!
