we can get geo location based on IP addresses of services and clients. So clients can select the closest services by comparing geo locations.

It is useful because clients always select services in the same datacenter (city).

don't use maxmind geolite2 to implement this feature because:

rpcx has been used in a company. IP addresses and geo locations of clients and servers are clear. We can set lat/lon before starting them
it will take more memory to use maxmind and cache their geo db
and it takes more time to query geo location from maxmind db

so this implementation uses clear latitudes and longitudes to calculate distance between clients and servers.
