Stefan Miklosovic commented on CASSANDRA-18438:
-----------------------------------------------
I am afraid we can not do this generic enough. We can not know that absolutely
every snitch will just call some endpoint and it will return the necessary
stuff. Some snitches can return dc and region in one response, some snitches in
two, some snitch will need some special treatment ... so I do not think it is a
good idea to do this like proposed. All we can do is to make life very easy for
a developer so adding new snitch will be comfortable and straightforward with
specific logic necessary if needed.

> Nowadays we have got about four public cloud platform snitchs ： EC2 snitch
> for aws, google cloud snitch for google cloud, alibaba cloud snitch for
> alibaba cloud and multi region snitch for ec2. And the common place for the
> first three is that we just need to query the zone center to get the ec2 /
> ecs id , so I think we can refactor the code , and if some new public cloud
> platform want to add one more snitch for himself, there is no need to pull a
> pr for him and configure some options in yaml is enough .
> Besides it would be even better that we may reuse the multic region snitch
> for ec2 for other public cloud platform.
