Netflix System Architecture
Netflix’s architecture is a remarkable example of scalable, resilient, and user-focused design. This document provides an overview of key components and principles that govern the system’s operation.
- Netflix Open Connect: Custom CDN for global streaming content distribution.
- Placement in ISPs: Servers inside ISPs’ data centers to reduce latency and increase throughput.
Microservices Architecture
- Decoupled Services: Functionalities as small, autonomous services.
- Independent Scaling: Services scaled independently based on demands.
Data Storage
- Cassandra: For distributed and available storage.
- MySQL: For customer and billing data.
- S3: For backup and archival.
Streaming Control Plane
- Playback: Determines best CDN and bitrate for streaming.
- Adaptive Streaming: Adjusts quality in real-time based on user’s network.
Recommendation Engine
- Machine Learning Algorithms: Personalized recommendations.
- Real-Time Processing: Apache Kafka for real-time data processing.
User Interface & Experience
- API Gateway: Central entry point for requests.
- A/B Testing: Constantly tests different UI versions.
Resilience & Redundancy
- Multi-Region Deployment: High availability and disaster recovery.
- Chaos Engineering: Tools like Chaos Monkey for resilience.
Monitoring & Analytics
- Real-Time Monitoring: Constant system health and performance monitoring.
- Big Data Analytics: Processing and analyzing data for insights using Apache Spark.
Security
- Content Encryption: Secure content delivery.
- Authentication & Authorization: User data and privacy protection.
- Java, JavaScript, React, Spring Boot, Docker, Kubernetes, etc.
