It is time to leave the 'bad neighborhood' of shared hosting. We analyze the critical performance differences between Shared and VPS architectures, specifically for the Norwegian market, focusing on I/O contention, kernel isolation, and the limitations of Apache mod_php.
Tired of unpredictable performance on oversold OpenVZ nodes? We break down why KVM's kernel isolation and dedicated resource allocation are critical for stability, security, and raw speed in the Norwegian hosting market.
Is your LAMP stack choking on traffic? Learn how to deploy Nginx as a high-performance reverse proxy in front of Apache. We cover config optimization, SSD I/O benefits, and keeping latency low in Norway.
Is Apache's memory bloat killing your server? We benchmark the industry standard against the lightweight contender, Lighttpd, to see which web server architecture reigns supreme for Norwegian high-traffic sites.
Is your server going down at 3 AM? Stop reactive fire-fighting. We detail the exact Nagios and Munin configuration needed to visualize performance and alert on failure before your users notice, specifically tailored for the Nordic hosting environment.
RAID 10 is not a backup strategy. In this guide, we cover scripting rsync, rotating MySQL dumps, and complying with Norwegian data laws (Personopplysningsloven) to ensure your VPS survives the worst.
Stop fearing the Slashdot effect. We dive deep into configuring HAProxy 1.4 for Layer 7 load balancing, covering kernel tuning, ACLs, and why raw I/O performance defines your failover speed.
Stop relying solely on client-side JS trackers. Learn to configure AWStats for granular server-side analytics, optimize log rotation on CentOS 6, and ensure compliance with Norwegian data laws without killing your Disk I/O.
It's 2011 and LulzSec is on the loose. Default configurations are a death sentence. Here is the battle-tested guide to locking down CentOS 6 and Debian Squeeze.
Running a mail server in 2011 is not for the faint of heart. Learn how to configure Postfix for maximum deliverability, secure it against relays, and keep the Norwegian Data Inspectorate happy.
Email delivery is broken. Most sysadmins configure Postfix poorly, leading to blacklisted IPs and lost business. Here is the definitive guide to setting up a bulletproof mail server on CentOS 6, securing it with TLS, and navigating Norwegian data privacy laws.
OpenVZ containers are cheap for a reason. If you care about consistent I/O and strict resource isolation, it's time to graduate to KVM. Here is the technical reality of hardware virtualization on the Linux kernel.
Is your Apache server choking on MaxClients? Learn how to deploy Nginx 1.0 as a high-performance reverse proxy to handle massive concurrency, reduce load, and secure your infrastructure on CentOS 6.
Stop gambling with 'burstable' RAM. We break down the architecture of Xen PV vs HVM, kernel tuning for Linux guests, and why true hardware isolation is the only path for serious Norwegian infrastructure.
Waking up at 3 AM to a crashed server is a rite of passage, but it shouldn't be a lifestyle. Learn how to combine Nagios for alerts and Munin for trends to secure your Norwegian infrastructure.
Stop relying on shared hosting for critical email. This guide covers the essential Postfix configuration steps to ensure deliverability, secure your MTA against relays, and keep the Norwegian Data Inspectorate happy.
Is Apache's process-heavy model killing your server's memory? We benchmark the industry standard against the event-driven speed of Lighttpd to see which web server reigns supreme for high-traffic Norwegian sites in 2011.
Is your budget VPS slowing down during peak hours? We dissect the architecture of OpenVZ, expose the dangers of 'Burst RAM', and explain why hardware virtualization like Xen or KVM is the only viable path for mission-critical Norwegian businesses.
