Which combination of steps should a solutions architect take to migrate the application with the LEAST amount of downtime?
(Choose two.)
Use an AWS Server Migration Service (AWS SMS) replication job to migrate the database server VM to AWS.
Use VM Import/Export to import the application server VM.
Export the VM images to an AWS Snowball Edge Storage Optimized device.
Use an AWS Server Migration Service (AWS SMS) replication job to migrate the application server VM to AWS.
Use an AWS Database Migration Service (AWS DMS) replication instance to migrate the database to an Amazon RDS DB instance.
Explanations:
AWS SMS supports VM replication, but it is typically used for migrating entire VMs. It is not the most efficient way for migrating only the database server VM when considering the large data size (500 TB).
VM Import/Export can be used for migrating VMs, but the 500 TB data size is too large to be efficiently imported using this method. It may not meet the low downtime requirement.
Snowball Edge is not suited for real-time replication of large data sets in a low-downtime migration scenario. It is more suited for batch data transfers.
AWS SMS can replicate the application server VM with minimal downtime, providing a continuous replication and near-zero downtime migration.
AWS DMS can be used to migrate the database to Amazon RDS with minimal downtime by enabling continuous data replication, which minimizes application downtime during the migration.
I deduce that the answer is:
Use an AWS Server Migration Service (AWS SMS) replication job to migrate the application server VM to AWS.
I organize that the answer is:
