Linux Kernel Live Patching for Zero Downtime

Lucas and Luna explore how enterprise Linux servers maintain availability without rebooting. They examine the mechanics of live kernel patching, specifically looking at systems like kpatch and kgraft that allow security fixes to be applied in memory. The discussion covers the risks of memory consistency, the role of the ftrace infrastructure, and why major cloud providers prefer this method over scheduled maintenance windows. Listeners will learn how a single byte change can propagate across thousands of nodes instantly. #LinuxKernel #LivePatching #ServerAvailability #CloudInfrastructure #TechEngineering #OpenSource #SystemAdministration #DevOps #Cybersecurity #FexingoBusiness #BusinessPodcast #TechnologyNews #EnterpriseIT #SoftwareMaintenance #KernelDevelopment #ZeroDowntime #Kpatch #LinuxCommunity Keep every episode free: buymeacoffee.com/fexingo
