Articles & Technical Guides
Cohesive, deeply researched architectural guides without paywalls, corporate hype, or course upsells. Every guide answers how the system operates under load, how it fails, and why engineers chose its trade-offs.
Introduction to Client-Server Architecture
Deconstructing the fundamental communication paradigm that powers the modern internet. Socket allocations, connection states, and request lifecycles.
Request Lifecycle & Transport Protocols
Tracing a network packet from socket allocation down through TCP handshake, TLS negotiation, and HTTP/2 application multiplexing.
DNS: How Domain Names Find Servers
Hierarchical tree resolution, recursive resolvers, root name servers, anycast routing, and TTL caching failure modes.
Kubernetes Services Explained: ClusterIP vs NodePort vs LoadBalancer
Three ways to expose your Kubernetes Pods. Understand how traffic reaches your applications, where each Service type is used, and how Kubernetes routes requests.
Inside a Linux Server: Epoll & File Descriptors
Why select() and poll() scale with O(N) complexity and how the Linux kernel solved the C10K concurrency bottleneck with epoll event readiness.
Docker Internals: Namespaces, Cgroups & OverlayFS
How container engines create the illusion of isolated operating systems using Linux PID/mount namespaces, control groups, and layered file systems.
Redis: In-Memory Caching & Eviction Policies
Single-threaded event loop, RESP protocol, LRU/LFU memory eviction algorithms, and thundering herd mitigation under extreme traffic surges.
Asynchronous Queues & Dead Letter Exchanges
Decoupling peak ingestion spikes from database writes using message brokers, consumer acknowledgments, idempotency keys, and retry dead-lettering.
Kafka: Distributed Commit Logs & Partitioning
Zero-copy sequential disk I/O, page cache exploitation, consumer group rebalancing, and partition leader election under network partitions.
Rate Limiting: Token Bucket vs Sliding Window
Mathematical comparison of token bucket, leaky bucket, and sliding window log algorithms for high-throughput API gateway protection.
Circuit Breakers & Cascading Outages
Preventing catastrophic retry storms when downstream microservices degrade, with automated three-state failure detection and half-open probe recovery.
