block device mapping
object mapping
batch storage mapping
datacenter mapping
Explanations:
Block device mapping allows you to specify additional storage volumes for your instances in AWS, enabling you to manage storage effectively when launching an instance or creating an AMI.
Object mapping is not a recognized term in the context of AWS storage management and does not relate to configuring volumes in EC2.
Batch storage mapping is not a valid term in AWS and does not pertain to the configuration of storage volumes in EC2 instances or AMIs.
Datacenter mapping is not a concept used in AWS for defining storage volumes, and it does not apply to the configuration of block storage for EC2 instances.
