Into which microservices should you split an online store?

An online store can be divided into the following microservices, each responsible for a specific business logic:

• Product Catalog — management of products, categories, attributes.
• User Management — registration, authentication, profiles.
• Cart and Checkout — adding products to the cart, calculating costs, placing orders.
• Payment — integration with payment systems, transaction processing.
• Order Management — storing and tracking order statuses.
• Warehouse and Logistics — inventory management, delivery.
• Reviews and Ratings — collection and display of user reviews.
• Notifications — email, SMS, push notifications.
• Admin Panel — content management, analytics.

This division allows for scaling and developing each service independently, as well as simplifying support and the implementation of new features.
