What is an S3 Access Point?
An S3 Access Point is a unique endpoint that can be used to access a specific S3 bucket. It is used to simplify access control management for applications that access multiple buckets.
What is an S3 Bucket Replication?
S3 Bucket Replication is a feature that allows you to replicate objects across multiple buckets in different regions. This can be used to improve data availability, reduce latency, and improve disaster recovery.
What is S3 Object Lock?
S3 Object Lock is a feature that allows you to prevent objects from being deleted or overwritten for a specified period of time. This can be used to protect against accidental changes or malicious intent.
What is S3 Cross-Origin Resource Sharing (CORS)?
S3 Cross-Origin Resource Sharing (CORS) is a feature that allows you to enable cross-origin requests from web browsers. This can be used to allow web applications to access S3 data from different origins.
What is S3 Object Lock Legal Hold?
S3 Object Lock Legal Hold is a feature that allows you to place a legal hold on objects in an S3 bucket. This prevents the objects from being deleted or overwritten, even if the expiration date has passed.
