OpenVZ is fine for hobbyists, but if you value strict resource isolation and kernel stability in 2009, Xen is the mandatory standard. Here is the technical breakdown of PV vs HVM and why we built CoolVDS on it.
Tired of unpredictable load averages and 'noisy neighbors'? We dive into the KVM vs. OpenVZ debate, benchmark the new Intel Nehalem architecture, and explain why true hardware virtualization is non-negotiable for serious database performance in 2009.
Tired of your MySQL process dying due to 'noisy neighbors'? We dismantle the OpenVZ overselling trap and explain why KVM is the only serious choice for production workloads in 2009.
The runC vulnerability changed everything. A battle-hardened guide to securing container runtimes, locking down privileges, and why KVM isolation is your only real defense against kernel exploits.
Containers aren't magic security boxes. From the recent runC vulnerability to kernel isolation, we break down how to secure your stack using 2019's best practices, leveraging strict KVM boundaries and immutable infrastructure principles.
Moving from monolith to microservices introduces network complexity that can kill performance. We analyze three battle-tested patterns—API Gateways, Circuit Breakers, and Asynchronous Eventing—and explain why underlying hardware latency is the silent killer of distributed systems.
Moving from monolith to microservices creates a distributed complexity nightmare. We analyze three battle-tested architecture patterns—API Gateways, Circuit Breakers, and Service Discovery—to keep your stack stable under load, specifically within the Norwegian hosting context.
Legacy monitoring tools like Nagios are failing in dynamic environments. Learn how to deploy a scalable Prometheus stack on NVMe-backed KVM instances to visualize real-time metrics, handle GDPR compliance in Norway, and eliminate 3 AM false positives.
Microservices solve scaling but break networking. Here is a battle-tested guide to deploying Istio 1.1 on dedicated KVM resources, managing the sidecar overhead, and achieving strict mTLS compliance in Norway.
Microservices aren't a silver bullet; they're a complex trade-off between agility and operational chaos. This guide explores the critical patterns—API Gateways, Circuit Breakers, and Service Discovery—needed to survive the transition in 2019, specifically within the context of Nordic network constraints.
Stop SSH-ing into your servers. In this deep dive, we explore why Pull-based GitOps workflows using Flux and Helm are the only scalable way to manage Kubernetes clusters in compliance-heavy Norwegian environments.
Monoliths are safe. Microservices are chaos. Learn the battle-tested patterns (Gateway, Circuit Breaker, Discovery) to tame your distributed system, and why your infrastructure choice determines your survival.
Serverless is the buzzword of 2019, but AWS Lambda isn't the only game in town. We explore running OpenFaaS on high-performance KVM instances to get the best of both worlds: developer velocity and infrastructure control.
Default Linux settings are killing your API performance. In this deep dive, we strip down the kernel, optimize Nginx upstreams, and discuss why hardware isolation matters for low-latency implementations in the Nordic region.
Alert fatigue and false positives are killing your DevOps culture. Learn how to deploy a modern Prometheus and Grafana stack on KVM to visualize real bottlenecks like CPU steal time and I/O wait.
Public cloud serverless functions offer convenience at the cost of control and predictable billing. In this technical deep-dive, we explore deploying a self-hosted serverless stack using OpenFaaS on NVMe-backed VPS instances to achieve sub-millisecond latency within Norway.
VPNs are just glorified backdoors. In 2019, the only secure network is one that assumes it's already breached. Here is how to build a Zero-Trust environment on CoolVDS using Nginx mTLS and strict iptables.
