Answer 1

Yes you can do it however it depends on the what you are using to Load balancer the traffic and handling the requests.

If you are using the Nginx you can use the split traffic and handle the traffic percentages accordingly.

http://nginx.org/en/docs/http/ngx_http_split_clients_module.html

If you are using the Istio also you can manage it with the

So it would be mostly depends on what you are accepting the traffic and proxy setup.
