Advanced Caching Strategies and Edge Computing Optimization. During the 20 minutes of my presentation, users worldwide will generate content equivalent to the volume created from the dawn of civilisation until 2003. The volume of content being created today is staggering. Consider this: from the beginning of recorded history until 2003, we produced roughly 5 exabytes of content. However, projections suggest a monumental leap to 147 zettabytes in 2024 alone, with video content leading the charge. With such exponential growth in content and its shortening life span, content delivery networks (CDN) face significant challenges in effectively caching large video libraries. While cache hit rates of 98% and higher are taken for granted, the figures above suggest that simple disc space inflation is not remotely enough to keep the cache hot ratio at the desired figures. This presentation explores many approaches, including tiered cache systems which use a hierarchical system of caching servers employing consistent hashing and other techniques to maximize scalability and performance while minimizing failover and downtime. It also covers one-hit-wonder elimination, utilizing simple counters to reduce cache pollution by avoiding storing unpopular content. It also addresses cache-state sharing, which employs Bloom-filter-based technology to further improve cache scalability and effective disk space utilization. Moreover, it will examine the deployment of edge computing to amplify caching efficiency in specific use cases. This talk was presented at Demuxed 2024, a conference by and for engineers working in video. Every year we host a conference with lots of great new talks like this in San Francisco.
