Find the right fix

Pick what is costing you. See what helps, the native tools, and where Zoorik fits.

What is costing you?

What helps

Pack the pods tighter and remove the machines the cluster no longer needs.

Where Zoorik fits

Coral rebalances workloads onto fewer, cheaper machines and removes the spare ones, within each app’s safety limits.
