Busy evenings: scaling your application

Give your application more Pods when things get busy, then let Kubernetes adjust the numbers.

A quiet evening in the house becomes a party. Two people handling drinks were plenty an hour ago. Now there’s a queue in the hallway. Getting a few more people to help is usually easier than asking those two to move six times faster.

Your application can work the same way. A Deployment can run several copies of a Pod, called replicas. Adding replicas is horizontal scaling. A Service sends traffic to the ready Pods behind it, so callers keep using the same address as the numbers change.
