Vertical scaling has a ceiling. When your InnoDB buffer pool exceeds physical RAM and NVMe I/O waits spike, it is time to talk about sharding. We explore application-level versus middleware-based sharding strategies relevant for high-traffic European workloads in 2020.
Manual security audits are a liability. Learn how to automate server hardening using Ansible and OpenSCAP to satisfy Datatilsynet requirements while keeping your infrastructure agile.
Microservices solve scale but introduce chaos. This 2020 guide covers implementing Istio on Kubernetes to regain control over traffic and security. Learn why underlying hardware latency matters for the sidecar pattern.
Latency isn't just a metric; it's a business killer. Learn how to tune the Linux kernel and Nginx for high-throughput API gateways, and why hardware isolation is your only defense against jitter.
Microservices solve scaling issues but introduce networking nightmares. Learn how to implement Istio 1.4 on Kubernetes to regain control, enforce mTLS, and why underlying infrastructure performance makes or breaks your mesh.
Manual security audits are a liability. Learn how to automate compliance using Ansible, OpenSCAP, and CIS benchmarks while keeping your data strictly within Norwegian borders.
When vertical scaling hits the hardware ceiling, sharding is the only way out. We explore practical sharding strategies using ProxySQL and PostgreSQL, aimed at maintaining low latency in Norwegian data centers.
Green dashboards often hide degraded performance. In this 2019 guide, we ditch legacy Nagios checks for a modern Prometheus and Grafana stack, specifically tuned for high-performance KVM environments.
Stop blaming your backend code for slow response times. A deep dive into Linux kernel tuning, Nginx optimization, and why hardware isolation is critical for API Gateways. Practical guide for DevOps engineers targeting the Nordic market.
Slow build times are the silent killer of developer velocity. We analyze how shifting from oversubscribed SaaS runners to dedicated NVMe-backed instances in Oslo can cut deployment times by 60%, ensuring GDPR compliance and raw I/O performance.
Microservices aren't a silver bullet; they're a complex trade-off between agility and operational chaos. This guide explores the critical patterns—API Gateways, Circuit Breakers, and Service Discovery—needed to survive the transition in 2019, specifically within the context of Nordic network constraints.

Firewalls are no longer enough. Learn how to implement Mutual TLS (mTLS), hardened SSH CAs, and granular access controls to survive modern threats. A technical deep-dive for Norwegian DevOps teams.
Disaster recovery isn't just about backups; it's about survival. Learn how to architect a failover strategy that keeps the Datatilsynet happy and your uptime intact using KVM, rsync, and Norwegian infrastructure.
It's not if, it's when. A battle-hardened guide to designing disaster recovery plans that actually work, focusing on data sovereignty, replication strategies, and the realities of Norwegian infrastructure in 2018.
It is July 2018. GDPR is in full effect. Is your disaster recovery plan compliant and battle-tested, or just a PDF gathering dust? We dissect real-world recovery strategies using KVM and NVMe storage.
Your build pipeline isn't slow because of your code—it's likely your storage backend. We analyze how I/O bottlenecks strangle Jenkins and GitLab CI, and why the post-GDPR world demands local Norwegian infrastructure.
Slow build pipelines kill developer productivity. We dissect storage bottlenecks, Docker layer caching strategies, and the impact of GDPR on your CI infrastructure choices in 2018.
