Microservices Architecture with Docker and Kubernetes
Microservices architecture enables building scalable, maintainable applications by breaking monoliths into smaller, independent services.
Microservices Benefits
Scalability Advantages
Independent scaling capabilities:
Service-specific resource allocation
Horizontal scaling flexibility
Load distribution optimization
Performance isolation
Development Benefits
Improved development workflow:
Team independence
Technology diversity
Faster deployment cycles
Easier maintenance
Docker Containerization
Container Benefits
