Migration from Monolithic Architecture to Microservices
Migration from Monolithic Architecture to Microservices
Article:
Our current application is built on a monolithic architecture, where all features, modules, and business logic run within a single codebase and deployment. While this structure has supported our operations, it presents limitations in scalability, maintainability, and independent deployment.
To address these challenges, we are planning a gradual transition towards mini-services or microservices architecture.
A monolithic application is developed as one unified unit.
Features:
- Single codebase.
- Single deployment.
- Tight coupling between modules.
Challenges:
- Difficult to scale specific modules.
- Complex maintenance and upgrades.
- Higher risk of failure affecting the entire system.
Mini-Services:
A modular approach that breaks the monolith into larger, logically grouped services.
- Suitable when complete microservices are not immediately practical.
- Reduced interdependencies.
- Easier transition from monolith.
Microservices:
A full decomposition into independent services focused on specific business functions.
Features:
- Each service handles a single responsibility.
- Independent deployment and scaling.
- Technology flexibility per service.
- Faster development and deployment.
- Independent scalability.
- Improved fault isolation.
- Easier maintenance and upgrades.
- Identify loosely coupled modules within the monolith.
- Design APIs to expose these modules as services.
- Shift shared components (like authentication and logging) into common services.
- Migrate module by module, starting with less critical areas.
- Monitor and adjust performance, security, and inter-service communication.
- Data consistency across services.
- Increased network communication.
- Deployment complexity.
- Monitoring distributed systems.
- REST or gRPC for communication.
- Docker and Kubernetes for containerisation.
- API Gateway for request routing and security.
- Centralised logging and monitoring tools.
Moving from a monolithic application to mini-services or microservices will enhance flexibility, reliability, and performance. However, it requires careful planning, phased migration, and the right technical infrastructure to ensure long-term success.
