Upgrade Your Kernel Without Rebooting
Apply kernel security patches and updates without downtime. Boot the new kernel alongside the old one, migrate workloads, and roll back instantly if anything goes wrong. No maintenance windows required.
Zero-Downtime Kernel Upgrades
Kernel upgrades are one of the most painful operations in production Linux. Teams delay security patches for weeks because they require reboots. Multikernel LiveUpdate removes that tradeoff.
Boot New Alongside Old
Launch the new kernel alongside the running one. Both kernels operate simultaneously on separate cores. No downtime window to schedule.
Migrate Workloads
Move applications from the old kernel to the new one gradually. Validate each migration before proceeding. Keep full control over the transition.
Instant Rollback
If something goes wrong, roll back instantly. The old kernel is still running. No reboot, no recovery procedure, no data loss.
Automatic Kernel Failover
When a kernel crashes today, the answer is reboot and hope. Multikernel LiveUpdate turns a minutes-long outage into a sub-second failover.
Continuous Monitoring
A standby kernel runs alongside your primary kernel, monitoring it via heartbeat. Always ready to take over.
Sub-Second Failover
When the primary kernel crashes, the standby takes over its devices and resumes service. No full reboot. No kdump. Applications continue running.
Automatic Recovery
After failover, the system automatically reclaims resources from the failed kernel and prepares a new standby. Self-healing without operator intervention.
Benefits
Ship Security Patches Faster
No more delaying kernel updates because of reboot windows. Apply patches immediately with zero application downtime.
Improve SLA
Sub-second failover means kernel crashes no longer translate to minutes of downtime. Directly measurable improvement in service reliability.
Reduce Operator Burden
No more scheduling maintenance windows. No more manual crash recovery. The system handles both planned and unplanned events automatically.
