# Building Distributed Systems at Scale

Building distributed systems that can handle millions of requests per day is both an art and a science. Over the years, I've learned valuable lessons about what works, what doesn't, and what to avoid.

## Key Principles

### 1. Design for Failure
Every component will fail eventually. Design your system assuming failures will happen.

### 2. Embrace Eventual Consistency
Strong consistency is expensive. Embrace eventual consistency where possible.

### 3. Monitor Everything
You can't fix what you can't see. Comprehensive monitoring is essential.

## Architecture Patterns

### Microservices
Breaking down monoliths into smaller, manageable services has been crucial for scaling our systems.

### Event-Driven Architecture
Using event sourcing and CQRS patterns has helped us build more resilient systems.

## Conclusion

Building distributed systems is challenging, but following these principles has helped me build systems that scale.
