We benchmark the stability and isolation differences between container technologies like OpenVZ/LXC and full hardware virtualization (KVM) to determine what actually belongs in production.
Cloud is not a magic bullet. Learn how to architect a fail-safe hybrid environment using KVM, HAProxy, and local Norwegian storage to beat latency and avoid vendor lock-in.
Container virtualization offers incredible density, but the shared kernel model exposes risks. From cgroups resource limiting to dropping capabilities, here is how we lock down instances at CoolVDS.
Hard drives die. Power grids fluctuate. In this deep dive, we explore high-availability setups using HAProxy, MySQL replication, and Norwegian data sovereignty to keep your infrastructure alive when disaster strikes.
Command line tools like 'top' only tell half the story. In this deep dive, we explore how to build a robust APM stack using Graphite and StatsD to diagnose bottlenecks before your Norwegian users experience latency.
Cloud redundancy isn't just a buzzword; it's an insurance policy. We analyze how to leverage Norwegian infrastructure alongside global providers using HAProxy, Puppet, and MySQL replication without breaking the bank.
Is your server 'up' but your users seeing 502s? Discover the difference between basic status checks and deep system metrics in 2013. We dive into Graphite, Collectd, and why hardware isolation matters for accurate data.
Move beyond the limitations of monolithic applications. Learn how to architect decoupled, resilient systems using HAProxy, Nginx, and low-latency KVM VPS infrastructure in the Nordic market.
Is your build queue growing faster than your commit history? We dissect disk I/O bottlenecks in Jenkins, implement distributed builds using SSH slaves, and explain why high-performance SSD storage is the only viable option for CI/CD in 2013.
Forget the cloud buzzwords. In 2013, real performance comes from understanding packet flow, bridges, and interrupts. We dive deep into architecting low-latency networks for Linux Containers and KVM without melting your CPU.
Container virtualization is the future, but networking across hosts is a nightmare. We explore how to build a robust multi-host network using LXC, GRE tunnels, and Open vSwitch on high-performance Linux clusters.
Is 'Integration Hell' eating your deployment window? Learn how to tune Jenkins on KVM infrastructure for reliable builds. We cover I/O bottlenecks, JVM heap tuning, and why local storage matters for Norwegian dev teams.
Backups are history; recovery is the future. A battle-hardened guide to implementing real Disaster Recovery (DR) for Norwegian infrastructure using MySQL replication, rsync, and HAProxy on KVM-based VPS.
Stop waking up at 3 AM for false positives. A battle-hardened guide to scaling monitoring with Zabbix and Graphite on KVM infrastructure in 2013.
Cloud PaaS is killing your budget. Learn how to deploy a high-performance, decoupled worker architecture using RabbitMQ and Node.js on dedicated KVM instances. The 'Serverless' future is actually just efficient system administration.
Cloud platforms promise a serverless future, but at what cost? Learn how to architect decoupled, message-driven systems using RabbitMQ, Celery, and KVM to achieve 'NoOps' efficiency without the vendor lock-in.
Is your server actually healthy, or is it just responding to ping? We dismantle the myth of binary monitoring and implement real metric-based visibility using Graphite, StatsD, and Logstash on high-performance KVM architecture.
A battle-hardened look at scaling infrastructure in 2013. We tear down the differences between Linux Containers and full virtualization, optimize for SSD I/O, and explain why KVM is the only sane choice for critical workloads in Norway.
