How to do load balancing works on app server level in SharePoint on-premise 3 tier architecture

Question

We are configuring SharePoint 2013 3 tier architecture. We are configuring services on servers. Now the requirement is:

1) All the services should be hosted on both the app servers, can we do this?

2) Both app server should balance there load

3) If one app server down then other app server should take care and system should not down

4) There is a feature NLB in Windows servers, will it work for app servers for the above cases?

Its urgent. Please help with the best approach.

Thanks in Advance.

Answer 1

1) Yes, with the exception of the User Profile Synchronization Service, if you choose to use it. It may only run on one server in the farm per User Profile Service Application (likely you'll only have one).

2) SharePoint has an internal round-robin load balancer. All you need to do is start the appropriate Service Instances.

3) Yep, that's how it works.

4) You do not need any load balancer technology in place, it is done for you.

Of course, for Web Front Ends, you do need a load balancer.
