Problem & solution

The challenge of stateful workloads—solved

Problem

Stateful workloads can’t be moved to cost-efficient resources

Organizations running resource-intensive, stateful applications cannot afford downtime. Since there is no widely adopted, commercial solution to move these stateful workloads to cost-efficient resources, they end up running in underutilized and expensive nodes.

Solution

Migrate stateful workloads with continuous uptime and lower costs

Container Live Migration enables previously unmovable workloads to be automatically packed into fewer optimized nodes. This helps eliminate resource fragmentation, ensuring maximum resource utilization and optimal instance selection while driving substantial cost savings.
