Any idea when these shows are going to be released? I think it is an important Topic for the 2018 exam
from the forums on the internet, RRS will be phased out shortly and will only continue to be available for those accounts that have RRS already deployed, Newer account and those that do not not have RRS deployed will no longer have access to RRS. Amazon already are already discouraging users in deploying RRS
***********"REDUCED_REDUNDANCY—The Reduced Redundancy Storage (RRS) storage class is designed for noncritical, reproducible data that can be stored with less redundancy than the STANDARD storage class.
We recommend that you not use this storage class. The STANDARD storage class is more cost effective."***********
IMO, there will be questions that favour the IA-OZ solution over the RRS Solution as AWS do require any solution to take account of the cost of its services.
