Understanding microservices
Microservices architecture decomposes an application into independent services that communicate over APIs. Each service is responsible for a specific business capability and can be developed, deployed and scaled independently. In contrast, monolithic applications package all functions into a single deployable unit.
Advantages of microservices
- Scalability: Services can scale horizontally based on demand, reducing costs compared with scaling entire monoliths.
- Resilience: Failure in one service doesn’t necessarily bring down the entire system; services can be restarted independently.
- Agility: Teams can develop and release features faster because services are smaller and have clear boundaries.
Potential challenges
- Operational complexity: Managing many services requires robust monitoring, logging and orchestration (e.g., Kubernetes).
- Distributed systems issues: Network latency, inconsistent data and eventual consistency must be handled carefully.
- Skill requirements: Teams need experience with containerization, service discovery and fault tolerance.
When to choose microservices
Microservices are ideal for large, complex applications with varied functionality and growth plans. Smaller projects or those without significant scalability needs might benefit from a monolithic approach initially.
