When Apigee Edge is deployed on private cloud, whether restarting requires a downtime or can we do a hot reload?

I am thinking of deploying Apigee Edge on private cloud. I have a small question, whether a downtime is needed to restart Edge services or can we do a hot reload? If we can do a hot reload, can you guys help me with some documentation or some details?

Thanks in advance.

There is no downtime, You will need to do a rolling restart / updates - there is no hot reload

It is a private cloud - there are many apigee services that constitutes this deployment spanning multiple VMs/instances. Deployment plan takes into account for HA, redundancy for all the services.

So you can perform a rolling restart/update to the entire apigee deployment without any downtime

Please refer to the Private cloud install and configuration guide for more details on the deployment scenarios and more details
