# Simple Hello World
- 1 Service
- 2 Versions
Iterates between the versions without any specific policy. (actually doesn't use the version for anything)
I think that by default uses `RANDOM`.
https://istio.io/latest/docs/reference/config/networking/destination-rule/#TrafficPolicy-PortTrafficPolicy
https://istio.io/latest/docs/reference/config/networking/destination-rule/#LoadBalancerSettings
Relies in automatic sidecar injection.
> Contains service account configurations, yet they are commented as not "necessary".
## Quick note
On this version I have "started" to use the full service name instead of the shorten version, aka:
```yaml
route:
- destination:
host: helloworld
```
Will be:
```yaml
route:
- destination:
host: helloworld.default.svc.cluster.local
```
It's overall a good practice to have, so not much of a reason to not do it.
