In 2014, relying solely on 'up/down' checks is a liability. Learn how to move from basic monitoring to deep instrumentation using the ELK stack and StatsD to uncover what's actually happening inside your Linux boxes.
Relying on a single US-based cloud provider is a risk to your uptime and data sovereignty. Learn how to architect a redundant, compliant infrastructure combining CoolVDS local KVM instances with public cloud bursting using HAProxy and MySQL replication.
Stop blaming your application logic for slow response times. We dive deep into Linux kernel tuning, Nginx configurations, and the hardware realities required to handle 10k+ concurrent connections in 2014.
Move beyond FTP and manual SSH scripts. Learn how to architect a 'push-to-deploy' workflow using Git hooks, Jenkins, and Puppet on high-performance KVM architecture.
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.
Is the Apache memory footprint killing your server uptime? We benchmark the industry standard against the lightweight contender, Lighttpd, to see which web server architecture handles high-concurrency loads on European networks.
Is Apache eating your RAM? We dive deep into migrating to Nginx + PHP-FPM, tuning process managers, and configuring APC to handle massive concurrency on Norwegian VPS infrastructure.
Is your web application stalling under load despite low CPU usage? The bottleneck might be PHP's default file-based session handling. Learn how to migrate session storage to Redis 2.6 for sub-millisecond access times and eliminate I/O blocking.
Stop letting I/O wait kill your application. A battle-hardened guide to MySQL 5.5 optimization, InnoDB tuning, and why hardware selection matters for Norwegian workloads.
Stop letting disk I/O kill your application performance. We explore why file-based sessions are obsolete, how to implement Redis 2.4 for robust session handling, and why low-latency infrastructure in Norway matters for your bottom line.
Default file-based sessions are a concurrency killer. Learn how to implement Redis 2.4 as a session handler to reduce latency, eliminate file locking, and handle thousands of requests per second on your Norwegian VPS.
Is your I/O wait spiking during peak traffic? It's probably your session handler. We break down why file and MySQL-based sessions fail at scale and how to deploy Redis 2.4 for sub-millisecond performance on CentOS 6.
In the era of the C10k problem, relying on default Apache Prefork configurations is a recipe for downtime. We benchmark Apache against Lighttpd to see which web server truly delivers for high-traffic Norwegian deployments.
Hard drives are where sessions go to die. In this deep dive, we replace the slow default file-based session handler with Redis 2.4 to achieve sub-millisecond latency for Norwegian e-commerce and high-traffic portals.
Is your Apache server choking on concurrent connections? We dissect the architecture of a high-performance Nginx reverse proxy, optimizing buffers, timeouts, and kernel parameters for the Norwegian hosting market.
It is 2011. If you are still running MyISAM on CentOS 5 with default settings, your I/O wait is killing your application. Here is the battle-tested guide to MySQL 5.5 tuning, InnoDB migration, and why raw disk speed matters more than you think.
Is your server swapping under load? We dive deep into the architecture of PHP-FPM, available natively in PHP 5.3.3+, and show you how to configure Nginx on CentOS 6 to handle thousands of concurrent connections without melting your hardware.
It is 2011, and the cloud buzzword is everywhere. But if you are running high-load databases on standard VPS hosting, you are likely suffering from the 'noisy neighbor' effect. Here is how to diagnose disk latency and why local RAID-10 beats cheap SANs.
With Oracle's acquisition of Sun shaking the open source community and PostgreSQL 9.0 introducing streaming replication, the database landscape has shifted. We benchmark the choices for high-performance hosting in Norway.
Is Apache's process-heavy architecture killing your server's load average? We benchmark Apache 2.2 against Lighttpd 1.4 on CentOS 5 to see which web server truly delivers for high-traffic Norwegian sites.
