EP139: Design a Live Streaming System
Live streaming involves sending video content over the internet in near real-time, which is both compute-intensive and time-consuming. The process includes encoding video and audio, connecting to point-of-presence servers, transcoding into different resolutions, segmenting videos, and using HTTP Live Streaming (HLS) for delivery. Additionally, content is cached by CDNs for efficient delivery, and videos can be stored for replay on platforms like Amazon S3.

Data Centers in System Design
A data center is a building full of servers, storage systems, and network equipment. Multi-data center architectures improve reliability and speed by connecting users to the nearest center using GeoDNS for traffic direction. Failover scenarios are managed by automatic detection and routing updates. Scaling strategies include component decoupling into microservices and using messaging architectures with message queues. Companies like Netflix and Amazon effectively implement these concepts for redundancy and scalability.

How Consistent Hashing Works?
Consistent hashing is a technique used for distributing keys uniformly across a cluster of nodes, minimizing the number of keys that need to be moved when nodes are added or removed. Steps include hashing keys and nodes using a hash function, placing them on a circular space or ring, and assigning keys to the nearest node in a clockwise direction. Virtual nodes help with load balancing by mapping physical nodes to multiple positions on the ring. This makes the technique scalable, load-balanced, and fault-tolerant, though it relies heavily on the quality of the hash function used.
