OK, even though the name “ELB” applies to both the old and the new IpFinder
in my opinion it isn’t really enough to change the name of the API classes now.

BTW in the docs the features are called Application Load Balancer and Classic Load Balancer,
so the abbreviations would be ALB and CLB, not ApplicationELB and ClassicELB.

To make sure new users are not confused by the names of the classes we need
to make the documentation clear:
1) Explain in the Javadoc of TcpDiscoveryElbIpFinder that it is for the Classic Load Balancers
2) Make sure that Javadocs of TcpDiscoveryElbIpFinder and TcpDiscoveryAlbIpFinder have
each other in “@see” tags
3) Make sure both are described and clearly distinguished at readme.io

Hi,

Regarding the name, it's not just about being a good name. I would point to
the official AWS documentation [1], [2]. The current ELB does not stand for
just the Classic Load balancer. Based on this documentation, the naming is
good. I agree with your suggestion about extending
TcpDiscoveryApplicationElbIpFinder from the TcpDiscoveryClassicElbIpFinder.
I can make the required changes.

Regards,
Uday
