The thing is, that we have implemented a server-side LB which speaks grpclb and this whole machinery seems to work pretty well - so we wanted to deploy it any day now. What is more, we wanted to make it open-source and we had some ideas to develop it further. So, could you be a little bit more specific on those topics?
1) How long (approximately) will grpclb be still supported? It would be fair to have some time to migrate to the new solution. 2) How will this new solution look like? I can't find any information about it, either on grpc's GitHub (no docs) or on this group. When I try to google "grpc load balancing" I still hit docs about grpclb. 3) Is this XDS solution going to work out-of-the-box, or, similarly to grpclb we will have to implement some part on our own (I mean, in grpclb we had to implement server-side of the protocol - how does it work with XDS)?
