Peer-reviewed, exhaustive architectural analyses of global platforms. Learn the non-trivial tradeoffs, failure recovery models, and kernel optimizations used at Netflix, Uber, WhatsApp, and mission-critical payment gateways.
Deep architectural analysis of Netflix's dual-plane streaming engine: Control Plane on AWS Microservices and Data Plane on custom Open Connect CDN appliances.
Architectural deep-dive into how Uber processes millions of GPS updates per second, maps drivers onto hexagonal spatial grids (H3), and performs real-time trip matching.
How WhatsApp sustained astronomical messaging scale using FreeBSD kernel modifications, the Erlang BEAM virtual machine, and lightweight actor concurrency.
Analyzing the classic trade-off between push (Fanout-on-Write) and pull (Fanout-on-Read) models in distributed social feeds, and why celebrity accounts break naive architectures.
Engineering payment gateways with zero double-charges: Idempotency keys, distributed consensus, double-entry ledgers, and reconciliation batching.
Practical engineering guide to horizontally partitioning relational databases: hash-based vs range-based sharding, cross-shard joins, and online resharding strategies.
Deep dive into Discord's persistence evolution: why MongoDB failed at 100M messages, how JVM GC pauses and tombstones plagued Cassandra, and how migrating to ScyllaDB (C++ shared-nothing) reduced p99 latencies from seconds to 15ms.
How YouTube ingests 500 hours of video every minute, splits raw footage into chunked directed acyclic graph (DAG) pipelines, encodes across VP9/AV1 multi-resolution codecs, and delivers petabytes globally via Google Global Cache.
Exhaustive engineering blueprint for high-scale rate limiting: comparing Token Bucket, Leaky Bucket, and Sliding Window Counter, atomic Redis Lua scripts, eliminating race conditions, and edge offloading with Envoy.
Comprehensive architectural analysis of Stripe's payment infrastructure: achieving five-nines availability, distributed idempotency locks, reliable webhook delivery with full jitter, and automated financial reconciliation.
