Consistency is a significant piece of information stockpiling; it guarantees that each change focused on a framework ought to be noticeable to all the members. S3 has two sorts of consistency models-

  • read-after-write consistency
  • Eventual consistency

Read after-write consistency: It enables visibility of a newly created object to all clients without any delays. similarly, there are perused after-erase and read-after-update. In read-after-update, the client can alter or make changes to a previously existing item while in read-after-erase ensures that perusing an erased record or article will come up short for all clients.

Eventual consistency: there is a time lag between the changes made in the data to the point where all participants can see it. It might not be visible immediately, but eventually, it appears.
