@AustinForest Please check the following KBA article to compare the EX2 Ultra to the PR2100/PR4100 which may be more suitable depending on your processing power needs.
Can you tell whether other provider will be supported? There are a bunch of S3 providers so I guess the changes needed are not that difficult to implement?
@AustinForest I cannot disclose any information regarding what will and will not be supported for any product or feature until the time of public announcement and availability of such product or feature.
