## missing side car

Add istio injection label

When you set the `istio-injection=enabled` label on a namespace

## Prepare istio for demo

normal install with side car. show the traffic and iptables

ambient mesh, show the traffic and iptables

multi clusters

issues with sidecars:

* take more resources
* difficult to maintain-ish
* traffic take a different network path

## Questions for the end

Can we replace service mesh? maybe yes, with cilium
