Docker is exploding in popularity, but standard configurations leave gaping security holes. We explore kernel isolation, Shellshock mitigation, and why running containers on KVM-based VPS is critical for Norwegian data compliance.
Docker is exploding in popularity across Norway's dev teams, but default configurations are a security nightmare. We dissect kernel namespaces, capability dropping, and why true hardware virtualization (KVM) remains the only safe harbor for production data.
It is late 2014 and Docker is eating the world. But running containers in production without hardening is negligence. We dissect LXC isolation, kernel exploits, and why KVM is your safety net.
With the recent explosion of Docker 1.3 and LXC 1.0, containerization is shifting from experiment to production. But shared kernels pose a massive security risk. Here is how to lock down your namespaces, drop capabilities, and why wrapping containers in KVM is the only sane choice for Norwegian data.
Docker 1.0 is here, but is it safe for production? We dive deep into the kernel-level risks of early containerization, how to lock down capabilities, and why wrapping containers in KVM is the only sane choice for Norwegian sysadmins.
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.
Docker 1.0 has just landed, changing the conversation around virtualization. We compare the emerging container tools against battle-tested LXC and OpenVZ, and explain why KVM is the only sane foundation for your stack in 2014.
Docker 1.0 is here, but running it in production requires more than a simple `docker run`. We dive into cgroups, namespaces, and why wrapping containers in KVM is the only way to satisfy Datatilsynet.
With the recent Heartbleed vulnerability shaking the internet, and Docker gaining traction in version 0.10, isolation is the priority. Here is how to secure your Linux Containers (LXC) effectively while maintaining performance.
It is 2014, and the container revolution is here. But before you deploy Docker to production, you need to understand the security risks of shared kernels. Here is a battle-hardened guide to locking down LXC and why KVM is mandatory for true isolation.
Docker is the new hotness, but running LXC in production requires serious hardening. We dissect cgroups, capabilities, and why KVM is still the safest boundary for Norwegian data.
While the buzz around Docker and lightweight virtualization grows, the security implications of shared kernels remain a massive blind spot. We dive deep into hardening LXC, managing cgroups, and why KVM isolation is the superior choice for Norwegian data sovereignty.
Container virtualization offers speed, but default configurations leave you wide open. We dive into capability dropping, cgroups resource control, and why KVM isolation is the ultimate security layer for Norwegian mission-critical data.
With Docker entering the scene and OpenVZ overselling rampant, how do you architect a stable hosting environment in Norway? We compare LXC, OpenVZ, and KVM strategies for the pragmatist.
With the Snowden leaks shaking trust in US hosting, choosing the right virtualization technology in Norway is critical. We dissect OpenVZ, LXC, and the emerging Docker toolset to determine the best stack for performance and isolation.
We benchmark the leading container technologies of 2013. Discover why raw LXC performance beats OpenVZ overhead and how to manage isolation without melting your kernel.
It is 2013, and Linux Containers (LXC) are exploding in popularity. But shared kernels mean shared risks. We explore capability dropping, cgroups, and why KVM remains the isolation king for Norwegian enterprise data.
While the industry buzzes about the new 'Docker' project, serious infrastructure relies on LXC. Here is a deep dive into isolating container traffic using Open vSwitch and HAProxy, ensuring your Norwegian workloads stay compliant and fast.
Container virtualization (LXC/OpenVZ) offers speed, but shared kernels invite disaster. Learn how to harden your isolation, drop kernel capabilities, and why KVM might be the safer bet for critical Norwegian workloads.
We benchmark the stability and isolation differences between container technologies like OpenVZ/LXC and full hardware virtualization (KVM) to determine what actually belongs in production.
Container virtualization offers incredible density, but the shared kernel model exposes risks. From cgroups resource limiting to dropping capabilities, here is how we lock down instances at CoolVDS.
