An organization has a hybrid cloud architecture consisting of its on-premises datacenter and AWS cloud-connected using AWS Direct Connect.
The organization is looking to migrate from an on-premises MySQL Database to an Amazon Aurora MySQL Database cluster.
What is the optimal solution for performing data migration in this scenario? The organization is particularly concerned about performing the migration as fast as possible.
Click on the arrows to vote for the correct answer
A. B. C. D.Answer: D.
Option A is incorrect because using DMS in this scenario is not the most optimal solution from an operational and cost-effective point of view.
It requires manual planning and execution of migration steps and additional infrastructure to support DMS.It also does not take advantage of database compatibility between the on-premises MySQL database and the Aurora MySQL cluster.
Option B is incorrect because it is not the most optimal solution.
It is not the fastest approach to performing the database migration.
Option C is incorrect because it is possible to create an Aurora Replica of an existing RDS MySQL database.
It is not possible to create an Aurora Replica of an on-premise MySQL database.
Option D is CORRECT because the Percona XtraBackup utility can be used to create backup files from the source database to an Amazon S3 bucket.
XtraBackup utility can copy source database backup files directly to S3.These files can then be directly imported into an Aurora MySQL cluster using the “Restore from S3” option.
As mysqldump utility uses DDL and DML statements to recreate the database schemas and load the data, it is a very time consuming process.
Therefore, using XtraBackup utility backups is a preferred method when time is a high priority consideration.

The optimal solution for performing data migration would be to use the AWS Database Migration Service (DMS).
Option A: Use AWS Database Migration Service (DMS) to migrate the data. AWS DMS is a managed service that helps in migrating databases to AWS quickly and securely. AWS DMS can migrate data from various sources, including on-premises databases, to Amazon Aurora MySQL database clusters. AWS DMS can perform full load migration and can also do ongoing replication. It also supports schema and data transformations.
Option B: Use the MySQL mysqldump utility to copy the data. The mysqldump utility is a MySQL tool that is used for creating backups or copies of databases. However, mysqldump can be slow for large databases, and the migration process can be time-consuming.
Option C: Create an Aurora Read Replica of the source database. After the migration is complete, promote the Aurora Read Replica to a standalone DB cluster. Creating an Aurora Read Replica can be a good option to create a replica of the source database in the AWS cloud. However, this process can take time, and it requires continuous replication between the source and the replica databases.
Option D: Use Percona XtraBackup utility to create backup files from the source database to an Amazon S3 bucket. Restore the Aurora MySQL DB cluster from those files. Percona XtraBackup is a backup utility that can create physical backups of MySQL databases. While this option may be faster than mysqldump, it requires more manual steps than using AWS DMS, and it may not be as efficient as AWS DMS for migrating data.
In conclusion, the optimal solution for performing data migration from an on-premises MySQL database to an Amazon Aurora MySQL database cluster in a hybrid cloud architecture consisting of an on-premises datacenter and AWS cloud, connected using AWS Direct Connect, is to use AWS Database Migration Service (DMS).
