The invalidation of Safe Harbor changed the game for European data hosting. We dive into practical DR strategies, MySQL GTID replication, and why data sovereignty in Norway is your best insurance policy.
Load average is low, but your site is crawling. We dissect the hidden metrics that matter in late 2015, from CPU steal time to the Safe Harbor data residency crisis.
Navigating the nascent container orchestration wars of 2015. We benchmark Docker Swarm, the newly released Kubernetes 1.0, and Apache Mesos to see which stack belongs on your Norwegian VPS infrastructure.
Migrating live production databases without killing your SLA requires military precision. Here is the exact replication strategy and my.cnf tuning we use to move heavy I/O workloads across the Nordic infrastructure.
Docker is taking over the world, but running it in production is a battlefield. We benchmark the three leading orchestration contenders—Kubernetes, Mesos/Marathon, and Docker Swarm—and analyze why your underlying VPS architecture decides who wins.
Cloud adoption was supposed to save us money. Two years later, the CFO is asking why our hosting bill rivals our payroll. Here is a pragmatic look at optimizing spend, rightsizing instances, and why data sovereignty in Norway matters more than ever in 2015.
Is your REST API choking under load? We dive deep into Linux kernel tuning, NGINX upstream keepalives, and why CPU Steal Time is the silent killer of API performance in virtualized environments.
Hypervisors are heavy. In a world demanding millisecond latency, Linux Containers (LXC) offer bare-metal performance with VM-like manageability. Here is why you should care.
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.
Stop trusting shared IPs with your business communications. A battle-hardened guide to configuring Postfix for maximum deliverability, speed, and security on a dedicated VPS environment.
Burstable RAM is a myth that kills databases. We analyze the architectural differences between OpenVZ containers and KVM virtualization, and why true hardware isolation is critical for high-load Norwegian workloads.
Is your budget VPS holding your application back? We analyze the architecture of OpenVZ, expose the truth about 'Burst RAM', and explain why kernel isolation matters for Norwegian business continuity.
Is disk I/O killing your application performance? Learn how to move session handling from the file system to Redis for sub-millisecond latency. A guide for high-traffic Norwegian setups.
Stop relying on public cloud repos. Learn how to deploy a battle-hardened, self-hosted Git server using Gitolite on Ubuntu 10.04 LTS. Optimised for Norwegian teams requiring strict data sovereignty and low latency.
Is your single Apache server choking under traffic? Stop throwing RAM at the problem. Learn how to implement robust load balancing with HAProxy 1.4 on CoolVDS to ensure zero downtime and handle the 'Slashdot effect'.
While the industry buzzes about 'The Cloud,' pragmatic CTOs know that network storage introduces latency. We analyze the trade-offs between SAN, NAS, and local RAID 10 in a post-RHEL 6 landscape.
It's 2010, and 'Cloud' is the new buzzword. But behind the marketing fluff, disk I/O is still the bottleneck killing your database performance. Here is how to configure storage for speed and compliance in Norway.
Stop letting noisy neighbors kill your MySQL performance. We analyze why KVM's hardware isolation beats OpenVZ containers and why serious System Administrators are migrating to fully isolated kernels.
Is Apache 2.2 eating all your RAM? We pit the industry standard against the event-driven challenger, Lighttpd, to see which web server delivers the best throughput for high-traffic Norwegian sites in 2010.
Is your database locking up under traffic spikes? Stop using MyISAM. We dive deep into my.cnf optimization, the InnoDB Plugin, and why disk I/O on 15k SAS drives (or SSDs) matters more than CPU for Norwegian VPS hosting.
Is your single LAMP server ready for a traffic spike? Learn how to scale horizontally using HAProxy 1.4 on Linux. We cover configuration, session persistence, and why low latency to NIX matters for Norwegian traffic.
Stop script kiddies and botnets cold. We dive deep into stateful packet inspection, fail2ban configurations, and kernel-level security for serious Norwegian deployments.
Tired of fighting for CPU cycles in oversold containers? We explore why Kernel-based Virtual Machine (KVM) is the superior choice for production workloads in Norway, offering true isolation and kernel-level control.
Stop losing business to blacklisted shared IPs. Master the art of deploying a hardened Postfix SMTP server on CentOS 5 with proper SASL auth, RBLs, and latency-optimized settings.
