S3 RTC is backed by an SLA with a commitment to replicate 99.9% of objects within 15 minutes during any billing month.

Is S3 eventually consistent?

Amazon S3 pioneered object storage in the cloud with high availability, performance, and virtually unlimited scalability, with eventual consistency. Millions of customers of all sizes and industries have used Amazon S3 to store and protect any amount of data for a range of use cases.

A: global file system => S3 gives you a global vue about your buckets deployed within regions. However, it is not a file system storage engine (that would be EBS) and buckets are created within regions not globally.

Which S3 storage classes is ideal for data with unpredictable access patterns?

Amazon S3 Intelligent-Tiering storage class automatically moves objects between two access tiers depending on the actual usage. As per AWS documentation, this Intelligent Tiering storage class is considered the ideal storage class for the long-lived data along with access patterns that unpredictable or unknown.

Navigate to the Management tab of the bucket and choose Replication. This is where you create a replication rule to migrate the existing objects. Choose Add rule. Creating this rule also enables standard CRR or SRR on the bucket.

What is S3 batch operations?

S3 Batch Operations is a managed solution for performing storage actions like copying and tagging objects at scale, whether for one-time tasks or for recurring, batch workloads. S3 Batch Operations can perform actions across billions of objects and petabytes of data with a single request.

Which is the best way to restrict access to data on S3?

Follow the principle of least privilege. Restrict access to your S3 buckets or objects by: Writing AWS Identity and Access Management (IAM) user policies that specify the users that can access specific buckets and objects.

Is S3 automatically replicated?

Amazon S3 CRR automatically replicates data between buckets across different AWS Regions. With CRR, you can set up replication at a bucket level, a shared prefix level, or an object level using S3 object tags.
