AWS DMS enables migration of product catalog data from Amazon Aurora PostgreSQL to Amazon MemoryDB for Redis, allowing applications to achieve microsecond read latency while keeping transactional data in Aurora.


<div><p>This article demonstrates how to migrate product catalog data from Amazon Aurora PostgreSQL to Amazon MemoryDB for Redis using AWS DMS, improving application performance through data offloading.</p><ul><li>AWS DMS enables one-time migration of frequently accessed data between different database engines</li><li>MemoryDB provides durable, in-memory storage with microsecond read and millisecond write latency</li><li>Solution uses CloudFormation to deploy Aurora PostgreSQL, MemoryDB, DMS, and supporting AWS services</li><li>Data staging occurs in Aurora PostgreSQL before DMS migration task transfers product catalog to MemoryDB</li><li>Post-migration, applications read transactional data from Aurora and product catalog from MemoryDB</li><li>Estimated hourly cost approximately $3.00 in us-east-1 region as of February 2023</li></ul><p>This approach separates transactional and frequently-accessed reference data across purpose-built databases, reducing bottlenecks and improving end-user experience.</p></div>
