eBPF-Powered Kernel Observability: Profiling Socket Drops, TCP Retransmits, and TLS Handshake Latency in Linux

Intermittent 502/504 errors between edge proxies and backend microservices often remain invisible in APM logs. Learn how eBPF kernel probes trace TCP backlog overflows and socket drops with zero application overhead.

Linux cgroups v2 & Memory Pressure Stalling: Diagnosing Kernel Thrashing and Sizing Container Limits in Production

Containers frequently suffer debilitating tail-latency spikes long before triggering OOM kills because the Linux kernel thrashes page cache allocations under pressure. Learn to interpret /proc/pressure/memory and configure memory.high in cgroups v2.

Zero-Trust Microservice Mesh with Mutual TLS: Terminating Envoy Proxy Sidecars on Bare-Metal Linux VPS

Perimeter firewalls leave internal microservices exposed to lateral attacks if an edge node is breached. Implement a zero-overhead service mesh using Envoy proxy sidecars and strict mutual TLS without the complexity of Kubernetes.
