Stop guessing why your production server is stalling. We dive deep into using eBPF tools (BCC, bpftrace) to debug latency and I/O bottlenecks on Linux, explaining why true KVM virtualization is non-negotiable for modern observability.
Kubernetes networking is often treated as magic until it breaks. We dissect the packet flow, compare CNIs like Cilium vs. Calico, and explain why underlying VDS performance defines your cluster's stability in 2024.
Microservices are great until network chaos sets in. Learn how to implement a Service Mesh (Istio/Linkerd) without destroying performance, utilizing CoolVDS's high-performance NVMe infrastructure for the specific needs of the Norwegian market.
Most monitoring dashboards are vanity metrics. Learn how to implement actionable Application Performance Monitoring (APM) using Prometheus, Grafana, and eBPF, while navigating Norwegian data sovereignty laws and hardware limitations.
Stop blaming your backend code for latency. Learn how to tune the Linux kernel and API gateway configurations to handle 10k+ concurrent connections without dropping packets, specifically optimized for Norwegian infrastructure.
Monitoring tells you the server is up. Observability tells you why the checkout is slow. We dive deep into the ELK vs. LGTM stacks, GDPR implications in Norway, and why self-hosting your telemetry on CoolVDS is the only safe bet in 2024.
Service meshes solve networking chaos but introduce complexity. Learn how to deploy Istio correctly on high-performance infrastructure without killing your latency budget.
Monitoring tells you the server is up. Observability tells you why the checkout API is timing out only for users in Bergen. We dismantle the difference, architect a full LGTM stack, and explain why data sovereignty in Norway is critical for your logs.
Is your cloud bill scaling faster than your user base? We dissect the hidden costs of hyperscalers, the technical reality of 'pay-as-you-go', and why Norwegian infrastructure offers a predictable financial advantage in 2024.
Cut through the hype of distributed systems. We dissect battle-tested microservices patterns—from API Gateways to Circuit Breakers—specifically optimized for Norwegian compliance and low-latency infrastructure.
A battle-hardened guide to deploying microservices that survive network partitions and high load. We analyze sidecar patterns, circuit breakers, and why infrastructure latency in Norway dictates architectural choices.
