Thanks,
Could you explain this:

"One Zone-Infrequent Access it has all the same properties of Infrequent access except all the above storage are in 3 availability zones but this storage class is only in one AZ so is prone to disasters." ?

What do you mean by all others types are in >=3 availability zones?
Does it mean that there are always synced s3 buckets over >=3 zones by default?
So we get 3 synced replicas by default? Each one stands as backup with primary one?

Yes as you can see in the chart by default other classes are stored in 3 or more Availability zones by default in AWS. One Zone-Infrequent Access but in one zone IF its only stored in a single availability zone which makes it a cheaper option

AWS is bound by the sla if the fail you to provide high availability they may have to return billions of dollars to customers. So, they automatically copy it over 3 AZ

Ok so these 3 do not operate as read replicas for example. By default they stand for backup?

I don't know this is a managed service by AWS and this is the info they give so basically they manage everything without you knowing and I don't know how they implemented it

So all 3 others buckets operate as replicas or standalone backups which do not accept connection?

All 3 replicas operate and accept connection, or they act as backup?
