But delaying patches to coordinate a migration or reboot is leaving your systems vulnerable, and your end-users may be noticing the service disruption involved.
TuxCare’s QEMUCare rebootless live patching solution enables cloud providers, virtual private server (VPS) hosts, or any other organization with QEMU-based virtualization systems to automate their infrastructure patching without needing to orchestrate an inconvenient reboot or disrupt virtual tenants’ systems.
Use end-of-life products securely – with new offerings from TuxCare! Endless Lifecycle Support (ELS) now covers Angular JS 1.8.3, Angular 16 & 17, and Apache Tomcat 8.5.
