Public cloud scalability often masks massive inefficiencies. We analyze the TCO of high-performance infrastructure in 2017, from NVMe economics to the looming GDPR regulations.
Is your application slow or is your VPS provider stealing cycles? In 2016, 'it feels fast' isn't a metric. We break down how to use the ELK stack, sysstat, and Nginx metrics to expose bottlenecks before Black Friday hits.
The 'castle and moat' security strategy is dead. Learn how to implement a Zero-Trust architecture on Linux using Nginx mTLS, hardened SSH, and strict iptables rules on your VPS.
It is October 2016, and everyone is rushing to containerize. But default Docker settings are a security nightmare waiting to happen. Here is how to harden your stack using namespaces, capabilities, and KVM isolation.
Backup is not disaster recovery. In this guide, we dismantle common data safety myths, explore 2016's evolving privacy regulations in Norway, and implement a master-slave replication architecture using KVM and NVMe storage.
Top doesn't tell the whole story. Discover how to identify bottlenecks using Nginx custom logging, PHP-FPM slow logs, and the ELK stack, while ensuring data compliance in Norway.
Hardware fails. RAID controllers panic. In the wake of the Safe Harbor ruling, relying on US-based backups is a compliance nightmare. Here is a pragmatic, code-heavy guide to DR planning for Norwegian infrastructure.
Docker is revolutionizing deployment, but default configurations are a security nightmare waiting to happen. From kernel exploits to the new EU-US Privacy Shield, here is how to lock down your stack in a post-Safe Harbor world.
Stop building distributed monoliths. A battle-hardened look at API Gateways, Service Discovery with Consul, and the infrastructure requirements to run Docker successfully in 2016.
Is the 'Serverless' hype worth the vendor lock-in? We explore how to implement event-driven architectures using Docker and Queues on high-performance Norwegian VPS infrastructure, avoiding cold starts and data sovereignty headaches.
Stop relying on basic ping checks. Learn to architect a scalable monitoring stack using Zabbix 3.0 and ELK on CentOS 7 to visualize real-time I/O bottlenecks and keep your data within Norwegian borders.
Docker is revolutionizing deployment, but its default configuration is a security minefield. We dive into kernel capabilities, user namespaces, and why KVM isolation is non-negotiable for Norwegian data compliance in 2016.
Is your dashboard all green while customers scream about timeouts? It is time to move from basic monitoring to deep system introspection. We explore how to debug latency in 2016 using ELK, Nginx custom logging, and why low-latency infrastructure in Norway is your best defense.
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.
With the ECJ invalidating Safe Harbor, reliance on US-only hosting is a liability. Here is a technical guide to building a compliant, low-latency hybrid infrastructure using Ansible, HAProxy, and local KVM instances.
Hardcoded IP addresses in your load balancers are a ticking time bomb. Learn how to automate service discovery using HashiCorp Consul and consul-template on a Linux stack.
As the Norwegian digital landscape evolves in 2015, VDS hosting emerges as the superior choice for businesses seeking the power of dedicated servers with the flexibility of the cloud.
Moving from monolith to microservices isn't just about code—it's an operational minefield. We explore service discovery, latency reduction, and why KVM isolation is non-negotiable for Docker deployments in 2015.
While AWS re:Invent just hyped 'Lambda', the real revolution for Nordic developers is building robust, event-driven worker queues. Learn how to architect non-blocking systems using RabbitMQ, Node.js, and solid KVM infrastructure without sacrificing data sovereignty.
In the wake of Heartbleed and Shellshock, the old firewall-castle model is obsolete. Learn how to lock down your infrastructure using 'Zero Trust' principles on Linux, specifically tailored for Norwegian data sovereignty.
Is 'Serverless' just a buzzword for PaaS? We dissect the emerging trend of decoupled architectures, Docker containers, and event-driven backends, and show you how to build a robust, server-agnostic infrastructure on CoolVDS right now.
Docker is changing deployment, but shared kernels pose risks. Learn how to lock down containers using Cgroups, Capabilities, and KVM isolation on trusted Norwegian infrastructure.
Navigating the chaos of Docker 1.3, CoreOS, and Mesos. Why your choice of underlying virtualization (KVM vs OpenVZ) determines your container stability in the Nordic market.
The 'Castle and Moat' security strategy is dead. With Shellshock and Heartbleed exposing internal vulnerabilities, sysadmins must adopt a Zero Trust model. Here is how to lock down your Norwegian VPS infrastructure using iptables, SELinux, and 2FA.
Is your server actually working, or is it just responding to ping? We explore the shift from binary monitoring to deep metrics analysis using Graphite, StatsD, and ELK on high-performance KVM infrastructure.
While the buzzword "Serverless" is creeping into Silicon Valley, the reality for European systems architects is pragmatic: it's about decoupling. Learn how to crush latency and scale workers using RabbitMQ, Docker, and raw KVM power.
Stop relying on load averages and ping checks. Learn how to monitor CPU steal, I/O wait, and Nginx throughput using Zabbix and custom Bash scripts on CentOS 7, specifically tailored for the Norwegian hosting market.
Containerization is exploding, but the shared kernel model exposes risks. We dissect namespaces, cgroups, and why wrapping your containers in a KVM VPS is the only sane choice for production.
With the release of Docker 1.0, everyone wants to containerize. But as a sysadmin managing Norwegian infrastructure, I see gaping security holes. Here is how to lock down LXC and Docker using AppArmor, capabilities, and the right virtualization layer.
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.
