Gravity inline documentation mentions the Load Balancing has to be handled outside of their cluster (from a DNS ?). But they are not explicit on the need for a virtual ip address to be set before the installation.
What are the network prerequisites for a DSP installation in a cluster ?
Do we need a DNS load balancer ?
A VIP set before the installation ?
Can we rely on the first node (master/controlplane) IP address, then switch to another ?
The low latency network mentioned as good practice between gravity nodes communication in DSP deployment procedure: do we have additional info about its' requirements ?
Then another question :
Can I start with a DSP standalone deployment, and make it a cluster later on ?
Obviously the standalone would be for testing/demoing while the hacluster would be for production, but this can be usefull for testing as well
