Technical insights and best practices for DevOps & Infrastructure
With the USD/NOK exchange rate volatile and energy prices soaring, the 'pay-as-you-go' model is becoming a liability. Here is a pragmatic technical guide to cutting cloud overhead without sacrificing IOPS or compliance.
Stop blaming your backend code for 504 errors. We dissect the kernel-level bottlenecks and Nginx configurations causing latency spikes, specifically tailored for Norwegian infrastructure constraints.
Green dashboards don't mean happy users. We dissect the architecture of high-fidelity monitoring using Prometheus and Grafana, the pitfalls of standard cloud metrics, and why data sovereignty in Norway is more than just a legal checkbox.
Container isolation is a myth if your kernel isn't secure. We dissect rootless modes, supply chain defense, and why Schrems II compliance demands strict infrastructure sovereignty in Norway.
Latency kills conversion. We dive deep into kernel-level optimizations, NGINX tuning, and why hardware locality in Norway matters for API performance.
Microservices solve scalability but introduce observability nightmares. This guide covers implementing Istio on bare-metal capable VPS infrastructure to handle traffic shaping, mTLS, and latency debugging without melting your servers.
Most DR plans are just PDFs that gather dust until the server room goes quiet. Here is how to build a battle-tested recovery strategy for 2022 using immutable backups, NVMe speed, and strict Norwegian data compliance.
Stop relying on manual 'kubectl apply'. Learn how to architect resilient, compliant GitOps pipelines using ArgoCD and high-performance KVM infrastructure in the post-Schrems II era.
Moving from monolith to microservices often results in a 'distributed monolith' that is harder to debug and slower to run. In this guide, we dissect the architectural patterns that actually work in 2022, focusing on API Gateways, resiliency, and the critical role of underlying infrastructure in the Norwegian market.
Monitoring tells you the server is down. Observability tells you why the database locked up. In this deep dive, we explore the distinct architectural differences, implement a 2022-ready OpenTelemetry stack, and discuss why high-cardinality data demands the NVMe performance found in CoolVDS instances.
A deep dive into K8s networking primitives for DevOps engineers. We cover CNI selection, tuning conntrack for high loads, and why raw compute performance matters for overlay networks. Written for the Norwegian market.
Serverless is an architectural pattern, not just a billing model. Dissect the reality of running event-driven workloads (OpenFaaS/Knative) on bare-metal capable VDS in Norway to solve GDPR headaches and eliminate cold starts.
Public cloud serverless functions are convenient until the bill arrives or Datatilsynet comes knocking. Learn how to deploy a high-performance, private FaaS architecture using OpenFaaS and K3s on CoolVDS NVMe instances.
Stop drowning in false positives. Learn how to architect a bulletproof monitoring stack using Prometheus, Grafana, and Loki, specifically tailored for the Norwegian regulatory environment and high-performance NVMe infrastructure.
A battle-hardened look at K8s networking in 2022. We dissect CNI choices, fix MTU fragmentation issues, and explain why underlying infrastructure defines your cluster's stability.
Stop relying on default K8s networking. We dissect CNI choices, IPVS vs. iptables performance, and kernel tuning to reduce latency for Norway-based clusters.
Slow builds aren't just annoying; they bleed budget. Discover how to identify I/O bottlenecks, optimize Docker layer caching, and why NVMe storage is non-negotiable for serious DevOps in the Nordic market.
Serverless doesn't have to mean AWS Lambda. Learn how to build a GDPR-compliant, high-performance FaaS architecture using OpenFaaS and KVM-based VPS in Norway.
Monitoring tells you the server is up; Observability tells you why the checkout failed for users in Bergen. A deep dive into the O11y stack (Prometheus, Loki, OpenTelemetry) for Norwegian DevOps teams facing GDPR constraints.
Microservices solve complexity but introduce chaos. This guide covers the practical implementation of Istio 1.15, the hidden 'sidecar tax' on CPU resources, and why hosting infrastructure in Norway matters for latency-sensitive meshes.
Migrating a live production database without losing data or sleep is an art. We dissect replication strategies, GDPR compliance, and why NVMe storage is non-negotiable for high-IOPS workloads in 2022.
Discover how to build a high-performance, GDPR-compliant serverless platform using OpenFaaS and Kubernetes on bare-metal KVM instances. We dismantle the 'cloud native' hype and show you how to regain control over your latency and data sovereignty.
Stop relying on ping checks. A battle-hardened guide to scaling Prometheus and Grafana on NVMe infrastructure, ensuring GDPR compliance and sub-millisecond latency within the Norwegian ecosystem.
Logs don't lie, but they are often silent about the root cause. Here is how to build a robust APM stack in 2022 using open-source tools, focusing on metrics, tracing, and the hardware reality beneath your virtualization.
Serverless is an operational model, not just a product. We analyze three robust patterns for 2022, discuss the GDPR implications of US clouds, and show how to build a compliant, high-performance FaaS platform on CoolVDS infrastructure.
Stop SSH-ing into production. Learn how to architect a resilient GitOps workflow using ArgoCD and K3s, ensuring GDPR compliance and sub-millisecond latency for Norwegian infrastructure.
Stop debugging random DNS timeouts and start architecting for throughput. We explore Calico vs. Cilium, the limitations of iptables, and why underlying hardware is the ultimate bottleneck for K8s networking in 2022.
Stop relying on sluggish shared runners. A battle-hardened guide to optimizing CI/CD pipelines using local caching, NVMe storage, and self-hosted runners compliant with Norwegian data laws.
Monitoring tells you the server is dead. Observability tells you why the database query timed out only for users in Bergen. A deep dive into the three pillars—metrics, logs, traces—and how to host them in a GDPR-compliant Norwegian infrastructure.
Most server bottlenecks are invisible to standard monitoring. Learn how to implement a full APM stack using Prometheus, Grafana, and accurate kernel metrics to debug latency in Norway's strict regulatory environment.
