Technical insights and best practices for DevOps & Infrastructure
Vendor lock-in is the silent killer of IT budgets. Learn how to architect a redundant, compliant infrastructure spanning CoolVDS local nodes and public clouds using HAProxy, MySQL replication, and 2013-era best practices.
Monolithic apps are dying, but SOA brings a new enemy: network latency. Learn how to implement a resilient service communication layer using HAProxy, local loops, and KVM optimization to maintain sub-millisecond response times in Norwegian datacenters.
Container virtualization promises efficiency, but shared kernels come with hidden costs. We compare OpenVZ, LXC, and KVM strategies for Norwegian DevOps teams facing the 'noisy neighbor' dilemma.
While the industry buzzes about 'Cloud,' the real performance battle is fought at the edge. We explore how to deploy high-availability Varnish nodes on KVM to solve latency challenges across Norway's unique geography.
Silence is not golden; it's a risk. Learn how to deploy a scalable monitoring architecture using Nagios and NRPE to catch failures before your customers do, specifically tailored for high-latency Nordic infrastructure.
Stop throwing code over the wall. In 2013, the divide between Dev and Ops is costing you money and sleep. Here is how to fix it with Puppet, culture, and KVM.
Stop wrestling with iptables spaghetti. Learn how to architect scalable, low-latency container networks using Open vSwitch on KVM, focusing on pure performance and Norwegian compliance standards.
Stop letting a single Garbage Collection spike take down your entire platform. We explore the emerging 'micro-service' patterns using Nginx, HAProxy, and KVM isolation to build resilient systems in Norway.
Is your Nagios server generating more I/O wait than your actual database? We dissect the architecture of scalable monitoring in 2013, moving from polling to pushing with Graphite, and why underlying hardware integrity is non-negotiable for Norwegian systems.
It is not a matter of if your RAID controller will fail, but when. In 2013, a backup is not enough—you need a recovery plan. Here is the battle-tested guide to MySQL 5.5 replication, rsync automation, and compliance with Datatilsynet.
Before you commit to the 'No-Ops' hype of expensive managed platforms, learn how to architect true decoupled scalability using RabbitMQ, Celery, and high-performance SSD VPS. A guide for 2013's serious engineers.
Manual deployments are killing your weekends. Learn how to automate your build-test-deploy cycle using Jenkins and Git, and why low-latency I/O is the secret weapon for fast builds.
Is your API gateway choking under load? Stop blaming your code. We dive deep into the Linux TCP stack, Nginx worker configuration, and hardware bottlenecks to squeeze every drop of performance out of your server infrastructure.
Hard drives fail and data centers go dark. In this 2013 guide, we architect a robust Disaster Recovery plan using MySQL 5.5 replication, Rsync, and KVM-based virtualization strategies tailored for Norwegian infrastructure.
Forget fragile single-server setups. Learn how to architect a fault-tolerant private network using Open vSwitch, HAProxy, and Linux bridging on KVM infrastructure. A deep dive for systems engineers targeting the Norwegian market.
Service Oriented Architecture brings agility, but also network nightmares. Learn how to architect a robust traffic management layer using HAProxy, Nginx, and Zookeeper on high-performance KVM instances.
Nagios alerts are useless if your disk I/O is choking. A battle-hardened look at monitoring high-load systems in 2013, why OpenVZ lies to you about load, and how to configure Zabbix and Munin for true visibility.
Monoliths are crumbling. Learn how to build a fault-tolerant service architecture using HAProxy and kernel-level tuning on high-performance KVM slices, specifically tailored for the Norwegian infrastructure landscape.
It is 2013, and ping checks are no longer enough. We explore the shift from basic monitoring to deep system introspection using StatsD, Graphite, and Logstash on high-performance KVM architecture.
Is your server actually slow, or is it just waiting on I/O? A deep dive into diagnosing Linux performance issues using vmstat, strace, and Nginx metrics, tailored for the Norwegian hosting landscape.
Tired of monolithic maintenance? We explore 'Serverless' concepts in 2013 using decoupled queues, PaaS-like worker patterns, and KVM isolation strategies on CoolVDS.
A green light in Nagios doesn't mean your server isn't melting. We analyze 'Steal Time', disk latency, and why KVM architecture beats OpenVZ for reliable metrics in the Norwegian hosting market.
Stop babying your monoliths. Discover how to implement asynchronous worker patterns using Redis, Supervisord, and KVM to achieve 'NoOps' scalability without the Heroku price tag.
RAID is not a backup strategy. In this deep dive, we explore automated, consistent backup workflows using rsync, mysqldump, and KVM snapshots, specifically tailored for Norwegian compliance standards.
Stop relying on a single Apache instance. Learn how to deploy a robust Layer 4/7 load balancer using HAProxy 1.4 to split traffic across CoolVDS KVM instances, ensuring uptime even when the traffic spikes hit.
Stop relying on user reports to know when your server is down. We dive deep into configuring Munin for trend analysis and Nagios for instant alerting on Ubuntu 12.04 and CentOS 6.
Is your load average spiking while CPU sits idle? You are likely a victim of the 'noisy neighbor' effect in modern cloud storage. We break down the difference between SAN and Local SSDs, how to tune Linux I/O schedulers, and why hardware isolation matters.
Stop trusting public WiFi. Learn how to deploy a military-grade OpenVPN server on a CoolVDS KVM instance using CentOS 6, iptables, and 2048-bit encryption.
Ditch the slow SVN and insecure FTP transfers. Learn how to deploy a secure, self-hosted Git server using Gitolite in Norway for millisecond-latency pushes and full data sovereignty.
Stop relying on US-hosted repos. Learn to deploy a secure, high-performance Gitolite server on Ubuntu 12.04 using strict SSH controls and SSD storage. Perfect for Norwegian teams needing compliance and raw speed.
