• Multi-channel management: RetailXPle needed to streamline order management and customer engagement across various online platforms like Tiki, Lazada, Shopee, and payment services such as MoMo, ZaloPay, and VNPay.

• Scalable architecture: The company required an architecture that could scale dynamically to handle peak loads during sales promotions while maintaining high availability and performance.

• Effective customer engagement: Providing personalized engagement and real-time notifications for offers, loyalty programs, and order updates was crucial for RetailXPle's growing user base.

• POS integration: RetailXPle needed to ensure that its Point of Sale (POS) systems, deployed across member stores, were seamlessly integrated with the cloud for real-time inventory and sales updates.

Azure-based Solution

1. Azure Kubernetes Service (AKS) for Microservices Orchestration: RetailXPle adopted Azure Kubernetes Service (AKS) to host and manage its core services as microservices, ensuring high availability and scalability. Each critical function, such as Order Management, Customer Engagement, E-commerce, Notification Service, and Loyalty & Promotions, is deployed as a separate .NET Core microservice, allowing RetailXPle to scale individual components independently based on demand.

2. Azure App Service for Web Application Hosting: The frontend web application, which interacts with the microservices, is hosted on Azure App Service. This setup provides seamless integration with the backend and allows automatic scaling, ensuring that users can access the application without performance degradation during high-traffic periods.

3. Azure Application Gateway with Web Application Firewall (WAF): To ensure security and traffic management, RetailXPle leverages Azure Application Gateway with a Web Application Firewall (WAF) to protect against threats and optimize load balancing. This also helps in managing requests from multiple channels, such as online shopping platforms and payment gateways, ensuring smooth and secure transactions.

4. Azure Event Grid and Service Bus for Event Handling: The architecture uses Azure Event Grid and Service Bus to handle event-driven communication between microservices. For example, the Order Management service generates events that trigger Notification Service to send real-time order updates or loyalty points accumulation. These event-based interactions ensure that different services remain decoupled while communicating efficiently.

5. Azure Functions for Real-time Push Notifications: Azure Functions are utilized for handling real-time push notifications. When specific events occur, such as order updates or new promotions, Azure Notification Hub sends push notifications to customers across multiple channels, enhancing customer engagement.

6. Azure Notification Hub for Unified Messaging: RetailXPle uses Azure Notification Hub to send push notifications to mobile devices. This centralized messaging service helps RetailXPle keep customers informed in real time. updates, promotions, and other events. Integration with external platforms ensures that notifications are sent across various social commerce and payment channels.

7. Azure Storage and Database Services for Data Management: For data storage, Azure Blob Storage and Azure SQL Database are used to handle warm and cold data, ensuring that customer, inventory, and transaction data are safely stored and easily accessible for analysis and reporting. This data is also streamed to the event-handling services for further processing.

8. POS Integration with Azure: RetailXPle POS systems in physical stores are connected to the cloud through the architecture, ensuring that sales, inventory, and transaction data are synchronized in real time. This integration helps RetailXPle maintain a unified system across both online and physical retail channels.
