Which solution will migrate the database in the LEAST amount of time?
Request a 1 Gbps AWS Direct Connect connection between the on-premises data center and AWS. Use AWS Database Migration Service (AWS DMS) to migrate the on-premises MySQL database to Aurora MySQL.
Use AWS DataSync with the current internet connection to accelerate the data transfer between the on-premises data center and AWS. Use AWS Application Migration Service to migrate the on-premises MySQL database to Aurora MySQL.
Order an AWS Snowball Edge device. Load the data into an Amazon S3 bucket by using the S3 interface. Use AWS Database Migration Service (AWS DMS) to migrate the data from Amazon S3 to Aurora MySQL.
Order an AWS Snowball device. Load the data into an Amazon S3 bucket by using the S3 Adapter for Snowball. Use AWS Application Migration Service to migrate the data from Amazon S3 to Aurora MySQL.
Explanations:
While AWS Direct Connect provides a high-speed connection, it does not guarantee immediate data transfer as the initial data still needs to be migrated over that connection. The migration process using AWS DMS would still be limited by the current data transfer bandwidth.
AWS DataSync can accelerate data transfer but still relies on the existing internet connection. It will not significantly reduce the overall migration time given the large size of the database (60 TB), which could still take a month or longer. AWS Application Migration Service is more suited for server migrations rather than database migrations.
Using an AWS Snowball Edge device allows the company to physically transfer the large dataset to AWS, bypassing the limitations of the internet connection. Once the data is in Amazon S3, AWS DMS can efficiently migrate the data to Aurora MySQL, significantly speeding up the migration process.
An AWS Snowball device can be used to transfer data quickly; however, the use of the AWS Application Migration Service is inappropriate for migrating a database. Instead, AWS DMS should be used for database migrations from Amazon S3 to Aurora MySQL.
I have a feeling that the answer is:
Order an AWS Snowball Edge device. Load the data into an Amazon S3 bucket by using the S3 interface. Use AWS Database Migration Service (AWS DMS) to migrate the data from Amazon S3 to Aurora MySQL.
