Aws Database Migration Service (AWS DMS) is a fully managed service that simplifies and accelerates database migrations to AWS. It supports homogeneous migrations (such as Oracle to Oracle) and heterogeneous migrations (such as Oracle to Amazon Aurora). AWS DMS can migrate your data to and from most widely used commercial and open-source databases. This service minimizes downtime during migration, allowing businesses to maintain operational continuity. Let’s explore the key features and benefits of using AWS DMS for your database migration needs.
