Curated article picks on systems, networking and cybersecurity — by Batiste Ansaldi, BTS SIO SISR IT technician.https://portfolio.net-flow.fr/en-GBhttps://portfolio.net-flow.fr/en/veille/https://portfolio.net-flow.fr/en/veille/The article that guided my log centralisation stack migration. Promtail officially reached EOL in March 2026 — I applied the migration across my 10 LXC containers and 2 Proxmox hypervisors.
