To increase the performance of its database solution, an organization is looking to migrate from its RDS MySQL database instance to an Aurora MySQL Database cluster.
What is the optimal solution for performing data migration in this scenario?
Click on the arrows to vote for the correct answer
A. B. C. D.Answer: C.
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.
Option B is incorrect because it is not the most optimal solution.
It requires manual steps to perform the data migration, and it does not take advantage of native capabilities offered by AWS.
Option C is CORRECT because it is possible to create an Aurora Replica of an existing RDS MySQL database.This automatically migrates the data from source to target.Once data migration is complete, it is possible to promote the read replica to a stand-alone cluster.This is the recommended approach to migrate data from the RDS MySQL database to an Aurora MySQL Cluster.
Option D is incorrect because it is not the most optimal solution.It requires manual steps to perform data export and import.
Additionally, it incurs costs associated with S3 storage.

https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraMySQL.Migrating.RDSMySQL.Replica.htmlSure, I'd be happy to explain the options and recommend the optimal solution for performing data migration from an RDS MySQL database instance to an Aurora MySQL Database cluster.
Option A: Use the AWS Database Migration Service (DMS) to migrate the data. The AWS Database Migration Service (DMS) is a managed service that helps migrate databases to AWS easily and securely. It supports a wide range of source databases, including MySQL, and can migrate data to Amazon Aurora with minimal downtime. DMS can also perform schema conversion and replication tasks to keep the source and target databases in sync during the migration process. This option is a good choice when you want to minimize downtime and simplify the migration process.
Option B: Use the MySQL mysqldump utility to copy the data. The mysqldump utility is a command-line tool that comes with MySQL and can be used to create backups of databases in a format that can be easily restored. This option involves creating a backup of the source database using mysqldump, copying the backup file to the target environment, and restoring the backup file to the Aurora MySQL DB cluster. However, this option may not be optimal for large databases as it can take a long time to complete the backup and restore process.
Option C: Create an Aurora Read Replica of the source database. After the migration is complete, promote the Aurora Read Replica to a stand-alone DB cluster. Creating an Aurora Read Replica of the source database and promoting it to a standalone DB cluster is a multi-step process that involves creating an Aurora Read Replica, monitoring the replication process, and promoting the replica to a standalone DB cluster once the migration is complete. This option can be useful when you need to minimize downtime, and the data volume is relatively small.
Option D: Copy the backup files from the source database to an Amazon S3 bucket. Restore the Aurora MySQL DB cluster from those files. This option involves creating a backup of the source database, copying the backup file to an Amazon S3 bucket, and restoring the backup file to the Aurora MySQL DB cluster. However, this option may not be optimal for large databases as it can take a long time to copy the backup file to S3, and then restore it to the Aurora MySQL DB cluster.
Based on the requirements mentioned in the question, the optimal solution for performing data migration from an RDS MySQL database instance to an Aurora MySQL Database cluster is option A: Use the AWS Database Migration Service (DMS) to migrate the data. This option can minimize downtime and simplify the migration process, and is suitable for both small and large databases. Additionally, DMS can perform schema conversion and replication tasks, which can be useful when migrating from a non-Aurora database to Aurora.
