A battle-hardened guide to slashing build times in 2019. We analyze the impact of NVMe I/O on Docker layers, kernel tuning for Jenkins runners, and why hosting your pipeline in Oslo matters for GDPR compliance.
Breaking the monolith is the easy part. Keeping distributed systems alive requires battle-tested patterns. We explore API Gateways, Circuit Breakers, and the infrastructure requirements needed to run them effectively in 2019.
A battle-hardened look at K8s networking performance in 2019. We dissect CNI plugins, kernel tuning, and why the underlying hardware determines whether your cluster flies or crawls.
Microservices solve scalability but break observability. We break down how to deploy Istio 1.1 for mTLS and traffic shaping, and why your underlying VPS hardware dictates success.
Transitioning from monolithic architecture to microservices requires more than just Docker containers. We explore battle-tested patterns, local latency realities in Norway, and the infrastructure needed to support distributed systems in 2019.
Stop manually applying manifests. We explore the newly released ArgoCD v1.0, the shift to declarative continuous delivery, and why high-performance NVMe infrastructure in Norway is critical for your reconciliation loops.
Monolithic architecture is suffocating your release cycle, but microservices introduce a complexity tax that bankrupts unprepared teams. Here is the battle-tested guide to API Gateways, Service Discovery, and Circuit Breakers using technologies available right now.
It’s May 2019. If you are still running containers as root or ignoring the runC vulnerability from February, your infrastructure is a ticking time bomb. Here is the battle-tested guide to hardening your Docker stack in Norway.
The runC vulnerability changed everything. A battle-hardened guide to securing container runtimes, locking down privileges, and why KVM isolation is your only real defense against kernel exploits.
Serverless doesn't have to mean vendor lock-in. We explore architectural patterns for running OpenFaaS on high-performance NVMe VPS to achieve event-driven scalability while keeping data in Norway and costs flat.
Is your application slow, or is it the network? In this deep dive, we move beyond 'top' and implement a full Prometheus + Grafana stack on Ubuntu 18.04. We analyze disk I/O latency, debug MySQL bottlenecks, and explain why hosting location in Norway matters for your metrics.
Moving from monolith to microservices introduces network complexity that can kill performance. We analyze three battle-tested patterns—API Gateways, Circuit Breakers, and Asynchronous Eventing—and explain why underlying hardware latency is the silent killer of distributed systems.
Moving from monolith to microservices creates a distributed complexity nightmare. We analyze three battle-tested architecture patterns—API Gateways, Circuit Breakers, and Service Discovery—to keep your stack stable under load, specifically within the Norwegian hosting context.
