- User Interface (UI) Layer
- Frontend: A web-based UI where users can browse and purchase wines. This can be hosted on AWS Amplify or S3 with CloudFront for content delivery.
- Application Layer (Microservices)
- Product Service: Manages wine inventory. Uses DynamoDB for storing product details.
- User Service: Manages user accounts and profiles. Uses RDS/Aurora for relational data storage.
- Order Service: Handles order creation and management. Uses DynamoDB for order data and places orders into an SQS queue.
- Process Order Service: Processes orders from the SQS queue. It updates order statuses and handles business logic related to order fulfillment.
- Recommendation Service: Provides personalized wine recommendations. Uses machine learning models, potentially leveraging SageMaker, and stores data in Redshift for analysis.
-
- Recommendation Stream Consumer: Consumes data from the Kinesis data stream and updates the recommendation service with new data.
- Notification Service: Sends email notifications (order confirmations, promotions) using SES.
- Data Storage Layer
- S3: Stores static assets like images of wine bottles, digital assets, etc.
- RDS/Aurora: Used for relational data that requires complex queries, like user data.
- DynamoDB: For high-speed, flexible NoSQL storage, like product catalog and orders.
- Redshift: For data warehousing and analytics.
- Integration and Messaging
- SQS: For decoupling microservices, handling message queues for asynchronous processing (e.g., order processing, inventory updates).
- Kinesis: For real-time data streaming and analytics, useful for user activity tracking, real-time inventory updates, etc.
- Security and Encryption
- KMS: For managing encryption keys used in the application, ensuring data security across services.
- Additional Considerations
- API Gateway: To manage and route requests to the appropriate microservices.
- Lambda: For serverless computing needs, such as running small functions triggered by events (e.g., image processing upon upload to S3).
- CloudWatch: For monitoring and logging. Elasticsearch Service: For advanced search capabilities across the product catalog.
