Difference between geocoding addresses using the locators inside ArcMap/ArcCatlog VS using the server REST url?

[AdityarajChavada]

Hello All,

We have recently made a new composite locator in 10.2.2 environment that improves our geocoding process. We also published the same composite locator on the 10.2.2 server (had to copy the locator because of the bug in 10.2.2) as a geocode service so that we can utilize that in the web applications.

My question to the experts are:

1) What is the best way or standards practices to batch geocode address (30 million records) using the REST end point of the service?

2) Is there a difference in using the physical locator in ArcMap/ArcCatlog to geocode the address Vs using the batch geocode process using the REST end point of the service?

Thank you in advance for your help.
