Technical insights and best practices for DevOps & Infrastructure
In the wake of Heartbleed and Snowden, data sovereignty and uptime are critical. Here is a battle-tested guide to DR using MySQL 5.6 GTID, Lsyncd, and KVM isolation on Norwegian soil.
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.
Is your monthly hosting bill outpacing your user growth? We analyze the hidden costs of I/O wait, the 'noisy neighbor' effect in OpenVZ, and why switching to KVM-based infrastructure in Norway might be your smartest fiscal move this year.
Stop paying for idle cycles. A pragmatic look at rightsizing infrastructure, leveraging SSD performance, and navigating Norwegian compliance laws in 2014.
It's 2014, and the buzz is all about PaaS and BaaS. But for serious scaling in Norway, relying on US-hosted 'serverless' platforms is a latency trap. Learn how to build your own high-performance worker clusters using Redis, Celery, and KVM.
Forget the buzzwords. True scalability in 2014 isn't about magical clouds; it's about decoupling your logic with message queues, Docker, and raw KVM performance.
Cloud ubiquity is a lie. Learn how to architect a fault-tolerant, hybrid infrastructure using KVM, HAProxy, and bare-metal performance without succumbing to the 'noisy neighbor' effect of massive public clouds.
Is your Nagios dashboard green while your users see timeout errors? In 2014, traditional monitoring isn't enough. We dive deep into system introspection, log aggregation with ELK, and why raw KVM performance is critical for true visibility.
Moving from monolithic architectures to decoupled services is painful but necessary. We explore API Gateways, Service Discovery without the bloat, and why KVM isolation beats early containerization for production stability.
Is your monitoring system generating more false positives than actual alerts? We dive deep into tuning Zabbix 2.2, optimizing MySQL I/O, and leveraging KVM isolation to build a surveillance architecture that actually works.
Your developers are spending more time sword fighting on office chairs than shipping code. Here is how to tune Jenkins, optimize I/O, and leverage Norwegian infrastructure to cut build times by 60%.
Move beyond the monolithic application. Learn how to architect robust microservices using Nginx, RabbitMQ, and KVM isolation, specifically tailored for the Norwegian hosting landscape.
It is April 2014, and Docker is changing how we deploy. But networking containers across multiple hosts remains a nightmare of NAT and port mapping. We explore manual bridging, Open vSwitch, and how to architect high-availability clusters on CoolVDS KVM instances.
Docker 0.9 changed the game, but cross-host networking remains a nightmare of NAT overhead and port conflicts. We dive deep into using Open vSwitch and pipework to build a scalable container network on KVM infrastructure.
With the recent Heartbleed vulnerability shaking the internet, and Docker gaining traction in version 0.10, isolation is the priority. Here is how to secure your Linux Containers (LXC) effectively while maintaining performance.
Is your application hanging during peak traffic? Stop blaming the code blindly. We dig into iostat, strace, and PHP-FPM logs to find the real bottlenecks in your stack.
Hardcoded IPs are the silent killers of uptime. In this deep dive, we explore implementing the 'Smart Stack' pattern using HAProxy and Zookeeper to create a self-healing service layer on high-performance KVM instances.
Is your REST API choking under mobile load? We dive deep into Nginx configuration, Linux kernel tuning, and the critical importance of I/O isolation to reduce latency for Norwegian users.
Nagios says your server is UP, but your customers are seeing 504 Gateway Timeouts. In the wake of Heartbleed, we explore deep system introspection using Graphite, Logstash, and strace to find the bottlenecks that simple monitoring misses.
Centralized load balancers are killing your microservices architecture. Learn how to deploy a distributed service discovery layer using HAProxy, Zookeeper, and SmartStack to reduce latency and eliminate single points of failure.
Microservices are exploding in popularity, but network fragility is the hidden killer. This 2014 guide details how to build a resilient 'Smart Proxy' architecture (the precursor to Service Mesh) using HAProxy, Zookeeper, and Airbnb's Synapse on high-performance KVM instances.
April 2014 Analysis: The industry is buzzing about PaaS and the elusive "No-Ops" dream. We dissect why owning your stack on high-performance SSD VPS is still superior to the "Serverless" black box for Norwegian enterprises.
Is your build server choking on disk I/O? In this deep dive, we explore optimizing Jenkins on Linux, the importance of KVM isolation, and why Norwegian data sovereignty matters more than ever post-Snowden.
Stop waking up at 3 AM for false positives. A Senior Systems Architect breaks down how to move from reactive ping-checks to proactive trend analysis using Zabbix, Graphite, and KVM-based isolation in the Norwegian market.
Docker 0.9 has changed deployment, but networking across multiple hosts remains a nightmare. We dive deep into manual OVS bridging and GRE tunnels to build a scalable cluster before orchestration tools catch up.
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.
Monitoring tells you the server is down. Deep diagnostics tell you why. We explore the emerging practice of Observability using Graphite, ELK, and KVM architecture, specifically tailored for the Norwegian hosting landscape.
Moving to a Service-Oriented Architecture? Don't let network fragility kill your uptime. Here is a battle-tested guide to implementing service discovery and load balancing using HAProxy and Zookeeper on high-performance KVM infrastructure.
Move beyond basic uptime checks. Learn how to diagnose high load, debug PHP-FPM bottlenecks, and why I/O wait on cheap VPS providers is killing your latency.
In 2014, a 'UP' status isn't enough. Learn why traditional port checks fail to detect application degradation and how to implement deep metric collection using Graphite, Logstash, and KVM-based introspection on Norwegian infrastructure.
