Explain the benefits and challenges of microservices architecture.

Short answer: Benefits: Scalability: Microservices allow for independent scaling of services based on demand.

Explain a bit more

Faster Development: Small, focused teams can develop and deploy services independently. Resilience: A failure in one service doesn’t affect the whole system. Technology Agnostic: Different services can be built using different technologies. Challenges: Complexity: Managing many services and their interactions can be difficult. Data Management: Ensuring data consistency across services can be challenging. Latency: Inter-service communication over a network can introduce latency. Deployment Overhead: Managing multiple deployments requires a sophisticated CI/CD pipeline.

Real-world example (ShopNest)

ShopNest splits Catalog, Cart, Order, and Payment into services so teams can deploy catalog changes without redeploying payments.
