Linux has been associated with performance, stability and scalability for decades. It makes sense. A large part of the Internet, cloud infrastructure, supercomputing, telecommunications, embedded systems and enterprise IT runs on Linux or on technologies closely connected to its ecosystem. But that explanation is starting to fall short. Linux remains a solid technical foundation, but
Few things are as fundamental in infrastructure management as subnet masks—and few are understood as superficially. Anyone who has ever configured a network interface has typed 255.255.255.0 almost on autopilot. But when it comes time to design the network architecture for a production environment, segment traffic across VLANs, size subnets for a private cloud deployment,
For years, many virtualization decisions were made almost by inertia. However, the current landscape has pushed many companies to revisit something that once seemed settled: whether it still makes sense to stay on the same platform or whether the time has come to explore alternatives that offer more technical control, less vendor dependence, and a
For more than three decades, the Linux kernel has grown with a comfortable paradox: a massive project maintained by hundreds of people worldwide, yet with a final, centralised step that has effectively passed through the hands of a near-single figure. Linus Torvalds didn’t just write the first lines of code; since 1991, he has also
For years, web encryption has relied on a basic assumption: if a service wants HTTPS, it needs a domain name. That’s practical—people browse names, not numbers—but also historical: certificate validation and lifecycle management were designed around DNS. That rule has started to change. As of January 15, 2026, Let’s Encrypt has announced general availability of
For years, Proxmox Virtual Environment (Proxmox VE) lived in a kind of “in-between land”: too powerful to be dismissed as a lab tool, yet still lacking the commercial gravity of the biggest names in virtualization. In 2025, that balance has broken. This open-source platform has solidified as a real — and in many cases preferred
In any modern infrastructure, backups are no longer a “nice to have”, but a structural component on the same level as storage or networking. When you work with Proxmox VE clusters, HA solutions, and mission-critical workloads, having a backup solution designed specifically for this ecosystem is what makes the difference between a fast recovery and
The Proxmox ecosystem has just taken an important step forward with the release of Proxmox Datacenter Manager 1.0, the first stable version of its centralized management platform. The tool is designed to solve a very specific problem: how to operate, monitor, and scale dozens of Proxmox VE nodes and clusters and Proxmox Backup Server instances
On a normal day, everything looks fine: the website is fast, APIs are calm, and monitoring dashboards stay in comfortable ranges. Then a big newsletter goes out, a paid campaign performs better than expected, or Black Week (Black Friday and Cyber Monday) kicks off. Suddenly traffic spikes and you quickly see whether your infrastructure is
AWS’s October 20 outage reminded us of a simple truth: resilience can’t be improvised. High availability (HA) within a single region helps, but it doesn’t replace a plan B that keeps services running when the common element too many components depend on fails (region, control plane, DNS, queues, identity, etc.). This guide lays out a
