Microservices Architecture: When and How to Implement

Microservices architecture has become the go-to approach for building scalable, maintainable applications. By breaking down a monolithic application into smaller, independent services, teams can deploy faster and scale more efficiently. However, it comes with its own set of challenges and complexities.

When to Use Microservices

Microservices are not a silver bullet. They introduce network latency and distributed system complexity. You should consider them when:

• You have large, complex applications requiring independent scaling components.
• Your teams are organized around business capabilities (Conway's Law).
• You need continuous deployment and fast iteration cycles.
• You have a diverse technology stack where different services benefit from different languages or databases.

Common Challenges

• Distributed System Complexity: Debugging across services is hard.
• Data Consistency: Achieving consistency without distributed transactions (Sagas).
• Operational Overhead: Requires advanced monitoring (Observability) and automation.
