Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Use the strangler fig pattern with AWS Database Migration Service (DMS) to replicate data between the monolithic database and new microservice databases.. The strangler fig pattern, combined with AWS DMS for continuous replication, allows gradual migration from a monolith to microservices. DMS replicates data changes in near real-time, ensuring consistency between the old and new databases. This approach minimizes risk and allows rollback if needed. Other options either do not support continuous replication or are not designed for database decomposition.

Answer

Use AWS Schema Conversion Tool (SCT) to split the monolithic database into microservice databases.

Answer

Use Amazon Aurora Global Database to replicate data across microservice databases.

Answer

Use AWS Glue to extract, transform, and load data from the monolithic database into microservice databases.

Question 2

A company is migrating a legacy three-tier application to AWS. The application tier is stateless and can be containerized, but the database tier is a commercial relational database that the vendor will only license on specific instance types. The company wants to reduce operational overhead for the database while keeping the same engine and minimizing schema changes. Which migration approach should a solutions architect recommend?

Accepted Answer

Replatform the database to Amazon RDS for the same engine using a vendor-supported instance class, and use Multi-AZ for high availability. Replatforming to Amazon RDS for the same commercial engine keeps SQL and driver compatibility while offloading patching, backups, and failover to AWS. Multi-AZ provides synchronous standby replication for high availability, and instance classes can be chosen to satisfy vendor licensing terms. Self-managing on EC2 reduces managed benefits, while NoSQL or Babelfish approaches change the engine and risk schema or feature incompatibility.

Answer

Rehost the database to Amazon EC2 on vendor-certified instance types and manage patching, backups, and high availability manually

Answer

Replatform the database to Amazon Aurora with aBabelfish endpoint to emulate the commercial engine's wire protocol

Answer

Refactor the database to a NoSQL model on Amazon DynamoDB to eliminate instance management entirely
