A deep dive into reducing build times and stabilizing deployments using distributed Jenkins slaves, tmpfs optimization, and high-performance KVM instances in 2013.
Tired of 3 AM downtime? Learn how to break your monolithic application into resilient services using Nginx, RabbitMQ, and KVM-based infrastructure available in Norway.
Is your API layer choking under concurrency? We dive deep into Linux kernel tuning, Nginx optimization, and the critical role of KVM architecture for Norwegian developers facing the mobile data explosion.
Before you scale your infrastructure, you must master the network layer. We dive deep into Linux bridging, VLAN tagging, and iptables routing for secure, multi-node environments on CentOS 6 and Ubuntu 12.04.
Slow builds are the silent killer of development velocity. We analyze how disk I/O, virtualization overhead, and kernel tuning impact Continuous Integration performance in 2013.
A deep dive into server virtualization strategies for 2013. We compare container-based virtualization (LXC, OpenVZ) against full hardware virtualization (KVM) and explain why kernel isolation is critical for Norwegian enterprises.
Nagios alerts at 3 AM are not a monitoring strategy. Learn how to pinpoint bottlenecks in PHP, MySQL, and Disk I/O using tools like New Relic, iostat, and Nginx stub_status to stabilize your infrastructure.
A deep dive into optimizing virtual network throughput using Linux bridging, virtio, and VLAN tagging for high-performance clusters in the Nordic region.
Bash loops are dangerous and Puppet is bloatware. Discover why Ansible's agentless architecture is the superior choice for managing KVM infrastructure in Norway.
Stop relying on default check intervals. Learn how to scale monitoring for high-load clusters using Graphite, tuned NRPE, and KVM-based isolation in the Norwegian market.
Stop managing deployments via FTP and SSH loops. Learn how to architect a high-performance Continuous Integration pipeline using Jenkins, optimize MySQL for test suites using tmpfs, and ensure compliance with Norwegian data laws—all running on KVM-isolated SSD infrastructure.
Stop relying on default Nagios configs. A battle-hardened guide to monitoring high-traffic Linux clusters, debugging I/O latency, and why pure SSD storage is the only way to scale in 2013.
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.
In 2013, default Linux configurations are killing your API performance. We dive deep into sysctl tuning, Nginx buffer optimization, and why SSD storage is the only viable path for low-latency REST architectures in Norway.
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.
It is April 2013. Stop using mysqldump for 50GB databases. We explore master-slave replication, Percona XtraBackup, and how to leverage SSD I/O to migrate critical data without killing your uptime.
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.
It is March 2013. LXC is entering the enterprise and Docker is making waves. But does sharing a kernel compromise your data? We explore cgroups, namespace isolation, and why hardware virtualization (KVM) remains the gold standard for security in Norway.
Hardware fails. RAID controllers degrade. In this guide, we bypass the marketing fluff and deploy a battle-tested Disaster Recovery plan using MySQL replication, Rsync, and Norwegian infrastructure laws.
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.
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.
Is your REST API choking under load? The bottleneck is likely not your code, but your TCP stack. We dive deep into Nginx 1.2 tuning, kernel parameters, and the hardware reality required for high-concurrency environments in 2013.
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.
Container virtualization offers raw speed, but shared kernels pose significant security risks. Learn how to lock down LXC and OpenVZ environments using cgroups, capabilities, and network isolation.
Vertical scaling hits a wall. Learn how to architect robust database sharding in 2013, manage latency across the Norwegian network infrastructure, and why hardware isolation is critical for data integrity.
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.
We benchmark the heavyweights of lightweight virtualization. Is OpenVZ's kernel sharing a ticking time bomb for your production stack? We dive deep into user_beancounters, LXC cgroups, and why KVM might still be the king for isolation.
