Overview

This project showcases a cutting-edge microservice architecture designed for scalable integrations across logistic, omni-channel, and partner systems. Utilizing the Spring framework, it supports both synchronous and asynchronous communications, enhancing system efficiency by 50%.

A key feature is the Load Balancer with Round Robin scheduling, enhancing system availability and throughput while reducing downtimes. CI/CD pipelines further streamline deployments across multiple server environments.

Performance is optimized through Time-Aware Least Recently Used (TLRU) caching and ThreadPool executors for swift concurrent IO operations. The architecture also ensures data reliability by managing both SQL and NoSQL databases in primary-replica configurations.

Seamless integrations are achieved with major marketplaces and logistic partners, including Amazon Marketplace and CloudTail, highlighting the system's adaptability and interoperability in dynamic digital ecosystems.

Architecture

The architecture of this microservice system is designed to maximize scalability, performance, and reliability while ensuring seamless integrations across various platforms. Below is a breakdown of its primary components and their interactions:

1. Microservice Framework:

• Spring: The backbone of the system, enabling modular service design and facilitating both synchronous and asynchronous communications.
• Aspect-Driven Architecture: Captures specific method executions, providing granular control over system behavior.

2. Load Balancing:

• Load Balancer (Round Robin Scheduling): Distributes incoming traffic across multiple instances of services to ensure even load, increased availability, and minimal downtimes.

3. Performance & Scalability:

• TLRU Caching: An evolved caching mechanism that considers both time and usage, ensuring optimal cache hits and reducing data fetch times.
• ThreadPool Executors: Employs a pool of worker threads, facilitating concurrent IO operations, maximizing throughput, and minimizing response times.
• Aspect, Event, & Annotation-Driven Architectures: These design patterns further boost system performance by leveraging efficient coding practices.

4. Data Management:

• SQL and NoSQL Databases: Ensures data reliability and availability by employing a dual-database strategy in primary-replica configurations. This architecture supports both structured and unstructured data needs.
• Distributed Locking: Incorporates Zookeeper for ensuring data integrity across microservices.

5. Integration & Routing:

• Marketplace & Logistic Integrations: The system has connectors to major marketplaces like Amazon Marketplace (SmartConnect & Seller Party models) and logistic partners like CloudTail and Amazon Shipping Provider. These integrations allow for real-time data synchronization and streamlined operations.
• Dynamic Routing Mechanism: Efficiently routes requests based on attributes, and custom annotations facilitate internal request routing using Java reflection.

6. Deployment & Automation:

• CI/CD Pipelines: Ensures swift, error-free, and automated deployments across various environments, from development to production.
• Configuration Manager: Utilizes @PropertySources annotations, enabling real-time configuration updates without system restarts.
• Environment-Based Properties: Ensures optimal performance by including properties relevant to the runtime environment.

7. User Interface & Feedback:

• Thymeleaf Template Engine: Crafts detailed shipping labels and order invoices.
• Exception Handling: Leverages ResponseEntityExceptionHandler to ensure RESTful responses during system exceptions.

8. Request Management:

• Request Filter: Authenticates and routes incoming requests to the correct controllers.

By intertwining modern technologies and innovative design patterns, this architecture assures a harmonious balance between performance, reliability, and scalability. It's primed for future enhancements and integrations with minimal disruptions.
