Hello ....

I've got a little question about the architecture of the server side.
If I don't make mistake a shard is composed of N front ends and behind
front ends there is some computers running different services.
And some where there is a login service (one per shard or one for all shard

Clients communicate with one front end of a shard.

But how clients are balanced between the N front ends of a shard ?
It will be done by a generic load balancer (hardware)
or a specific service from NEL ?

The source code of the load balancer and the front end are delivered with

If there a description of all NEL services ?
what is the welcome service ?

sorry for all this questions ....
