Implementing microservices involves breaking down a monolithic application into smaller, loosely coupled services that can be developed, deployed, and scaled independently. Here’s how I’ve implemented microservices and the tools used:

Implementation of Microservices

Example Project: Auto-Debit Payment Feature for Asset Leasing Product

Architecture Overview:

• Services:
  • Mandate Management Service
  • Payment Processing Service
  • Receipt Management Service
  • Reversal Service

Detailed Implementation

1. Mandate Management Service:

• Responsibilities: Handles registration, update, and lifecycle of mandates.
• Technology Stack: .NET Core, SQL Server for data storage.
• Endpoints:
  • POST /mandates
  • GET /mandates/{id}
  • PUT /mandates/{id}
  • DELETE /mandates/{id}

2. Payment Processing Service:

• Responsibilities: Processes payments using GoCardLess or file-based processing.
• Technology Stack: .NET Core, Azure Functions for serverless processing.
• Endpoints:
  • POST /payments
  • GET /payments/{id}

3. Receipt Management Service:

• Responsibilities: Creates and manages receipts for successful payments.
• Technology Stack: .NET Core, SQL Server.
• Endpoints:
  • POST /receipts
  • GET /receipts/{id}

4. Reversal Service:

• Responsibilities: Handles reversal of payments.
