Microservices (or microservice architecture) is an approach to software development in which applications are built as a collection of small, independent services, each responsible for a single specific function. Each microservice can have its own database and business logic, making applications more flexible, scalable, and easier to manage.
Key Features of Microservice Architecture
- Independent Deployment: Each service can be deployed and updated independently.
- Single Responsibility: Every microservice performs a specific task (e.g., user management, payment processing, etc.).
- Technology Flexibility: Different services can be developed using different programming languages or databases.
- Fault Isolation: If one service fails, it doesn’t bring down the entire system.
- Horizontal Scalability: Only the services that need to handle increased traffic can be scaled independently.
Use Cases for Microservices
- Large-scale web applications
- E-commerce platforms
- Financial technology (Fintech) solutions
- Cloud-based SaaS applications
- Backend services for mobile apps
