Root in a container is root on the host. This guide strips away the marketing fluff to show you how to actually secure Docker and Kubernetes workloads in 2024, focusing on kernel isolation, capability dropping, and why infrastructure choice matters for Norwegian compliance.
RAID is not a backup. Your shell scripts are likely broken. A battle-hardened guide to DR strategies in 2020, focusing on Norwegian data sovereignty, automated integrity checks, and achieving sub-minute RTO.
Offsite backups are useless if your restoration time exceeds your RTO. A deep dive into compliant, high-speed disaster recovery architectures using KVM and NVMe storage in the Norwegian market.
It is not a matter of if your server will fail, but when. In the wake of the May 2018 GDPR rollout, data loss is no longer just an operational inconvenience; it is a legal liability. Here is a battle-tested guide to automated recovery workflows, database consistency, and why NVMe storage matters for RTO.
It’s 3 AM. Nagios says the server is up. Your users say the checkout is broken. We dissect the critical shift from monitoring to observability using the modern 2018 stack: Prometheus, ELK, and proper KVM infrastructure.
It is July 2018. Everyone wants Kubernetes, but few need the headache. We benchmark the big three orchestrators against the reality of latency, GDPR, and disk I/O.
The perimeter is dead. In the wake of GDPR's 2018 enforcement, relying on a VPN is negligence. Learn to implement a 'Verify, Never Trust' architecture using Nginx mTLS, strict iptables, and isolated NVMe instances.
