Docker 1.2 is here, but managing containers across multiple hosts is still the Wild West. We compare Fig, CoreOS Fleet, and the emerging Kubernetes to see what actually works in production.
Backups save files; Disaster Recovery saves businesses. A battle-hardened guide to replication, failover, and keeping your data inside Norway's borders using 2014's best practices.
While Silicon Valley hypes 'Fog Computing', Norwegian sysadmins know the reality: physics always wins. Here is how to architect distributed Linux nodes for sub-10ms latency using Nginx, Varnish, and local KVM instances.
A deep dive into kernel-level optimizations and config tuning for Nginx 1.6 and the new HAProxy 1.5. Learn how to handle 10k+ concurrent connections without melting your CPU.
Is your monolithic application slowing down your release cycles? We explore the emerging microservices trend, Docker 1.1 usage, and why low-latency KVM infrastructure is critical for distributed systems.
Google's new Kubernetes project is rewriting the rules of cluster management. We dive deep into the networking primitives—namespaces, bridges, and overlays—that make multi-host Docker deployments possible today.
Nagios says your server is online, but your users are seeing 504 errors. In this 2014 guide, we dismantle the 'green light' fallacy, explore the emerging ELK stack for deep system introspection, and discuss why high-IOPS storage is non-negotiable for logging infrastructure in Norway.
Docker 1.0 is here, but is it safe for production? We dive deep into the kernel-level risks of early containerization, how to lock down capabilities, and why wrapping containers in KVM is the only sane choice for Norwegian sysadmins.
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.
Nagios says your server is up, but your customers are getting 504 timeouts. Stop relying on simple ping checks and start implementing deep system diagnostics with Graphite, Logstash, and KVM.
Docker v1.0 is here, but multi-host networking remains a nightmare. We analyze the "IP-per-Pod" model in Google's new Kubernetes project, dissect linux bridging, and explain why your underlying VPS architecture determines if your cluster flies or fails.
Manual file uploads are killing your uptime. Learn how to build a rugged, automated deployment pipeline using Git hooks and Jenkins on high-performance KVM instances.
Hardware fails. Networks congest. In a post-Snowden world, relying on a single US-based cloud is professional negligence. We detail a battle-tested disaster recovery setup using KVM, MySQL Replication, and Oslo-based redundancy.
A battle-hardened guide to keeping Norwegian infrastructure alive when hardware fails. Covers MySQL replication, rsync strategies, and KVM isolation on CoolVDS.
Default Linux configurations are not built for thousands of concurrent REST API requests. In this guide, we strip down the kernel, tune Nginx workers, and explain why high-IOPS SSD storage is the only viable option for modern SOA deployments in Norway.
The traditional network perimeter is dead. Discover how to implement a 'Never Trust, Always Verify' security model on Linux using KVM isolation, granular iptables, and strict access controls suitable for 2014's threat landscape.
Stop relying on mysqldump. Learn how to migrate large MySQL datasets using Percona XtraBackup and SSH piping without triggering prolonged downtime, specifically tailored for latency-sensitive Norwegian infrastructure.
With Docker hitting version 1.0 last month, the container revolution is officially ‘production ready’. But running one container is easy; managing a cluster is war. We compare CoreOS fleet, Mesos, and the emerging Kubernetes to help you survive.
The 'Castle and Moat' security strategy is dead. Following the Heartbleed wake-up call, we explore how to implement a Zero-Trust network model on your VPS using iptables, strict SSH key management, and internal encryption. Stop trusting your LAN.
Monitoring tells you the server is up. Deep diagnostics tell you why the database locks up every Tuesday at 14:00. A 2014 guide to moving from passive checks to active insight on Norwegian infrastructure.
Firewalls aren't enough anymore. Following the Heartbleed wake-up call, we explore how to implement a 'Zero-Trust' architecture on Linux servers using KVM, IPTables, and 2FA. Data sovereignty in Norway has never been more critical.
It is not a matter of if your server will fail, but when. In the wake of Heartbleed and increasing data sovereignty scrutiny in Norway, this guide covers battle-tested strategies using rsync, MySQL replication, and KVM snapshots to keep your infrastructure alive.
Hard-coding IPs in 2014 is a recipe for disaster. We explore how to implement a fault-tolerant service communication layer using the newly released HAProxy 1.5 and Consul to tame your microservices architecture.
Nagios tells you the server is up. It doesn't tell you why the checkout takes 5 seconds. Here is how to implement real Application Performance Monitoring on a Linux VPS without breaking the bank.
Stop letting monolithic architecture kill your uptime. We explore battle-tested microservices patterns using Nginx, KVM, and SOA principles suitable for the high-compliance Norwegian market.
Microservices are replacing monoliths, but managing connections is a nightmare. Learn how to architect a 2014-era 'Service Mesh' using HAProxy 1.5, Consul, and robust KVM infrastructure.
The 'castle and moat' security strategy is failing. In the wake of Heartbleed, we explore how to implement Forrester's Zero Trust model using IPTables, SSL mutual authentication, and strict access controls on Ubuntu 14.04 LTS.
The traditional "hard shell, soft center" security model is dead. Following the Heartbleed wake-up call, we explore how to implement rigorous internal segmentation and de-perimeterization on your VPS environments using standard Linux tools available in 2014.
Stop relying on mysqldump. Learn how to migrate high-load databases using Percona XtraBackup and replication without killing your uptime, tailored for the Norwegian hosting landscape.
Stop relying on basic ping checks. Learn how to implement metrics-based monitoring using Graphite, collectd, and Nagios to visualize performance bottlenecks before they kill your uptime.
