Is there a way to run horizontal scaling on multiple pods in a GCP deployment?

[bruno-curta]

We did a GCP implementation running on the default deployment.yaml file (here) and that was working great.
When we tried to make a horizontal scaling the application started to present a strange behavior, sometimes showing the flows created, sometime not. It was unable to save new flows, because the data was storage into different pods from time to time.
Is there a way to fix that?
Any support really appreciated.
Thanks
