Which solution will meet these requirements?
Create an Amazon Aurora MySQL Serverless v1 DB instance. Migrate the RDS DB instance to the Aurora Serverless v1 DB instance. Update the connection settings in the application to point to the Aurora reader endpoint.
Create an RDS proxy. Configure the existing RDS endpoint as a target. Update the connection settings in the application to point to the RDS proxy endpoint.
Create a two-node Amazon Aurora MySQL DB cluster. Migrate the RDS DB instance to the Aurora DB cluster. Create an RDS proxy. Configure the existing RDS endpoint as a target. Update the connection settings in the application to point to the RDS proxy endpoint.
Create an Amazon S3 bucket. Export the database to Amazon S3 by using AWS Database Migration Service (AWS DMS). Configure Amazon Athena to use the S3 bucket as a data store. Install the latest Open Database Connectivity (ODBC) driver for the application. Update the connection settings in the application to point to the Athena endpoint
Explanations:
Amazon Aurora MySQL Serverless v1 may provide benefits such as automatic scaling and on-demand capacity, but migrating to Aurora would still require application changes. It does not inherently resolve connection re-establishment issues during failover since the application would need to handle endpoint changes, which may not happen without a restart.
Creating an RDS Proxy allows the application to maintain persistent connections to the database. RDS Proxy helps manage database connections, providing a failover mechanism that enables the application to automatically reconnect without requiring a restart, thus meeting the requirement.
While creating an Aurora MySQL DB cluster and using an RDS Proxy may offer benefits, the added complexity and migration to Aurora are unnecessary for resolving the connection issue. The primary concern of re-establishing connections can be adequately addressed by just implementing the RDS Proxy with the existing RDS instance.
Exporting the database to Amazon S3 and using Athena is not a solution for maintaining live connections to a database. This option would significantly alter the architecture and is not suitable for real-time database interactions, thus failing to address the connection loss issue effectively.
As far as I’m aware, the answer is:
Create an RDS proxy. Configure the existing RDS endpoint as a target. Update the connection settings in the application to point to the RDS proxy endpoint.
