In your enterprise portfolio, you are likely to have multiple types of databases. When you migrate to Amazon Web Services (AWS), you can choose to do a “lift and shift” of your databases (rehost) or modernize your applications by switching to AWS managed database services (replatform).
If you choose to rehost your database, AWS provides a number of services and tools that can help you securely move, store and analyze your data. If you choose to switch to an A
WS managed database service, AWS offers a multitude of options so you never have to trade off functionality, performance, or scale. For more information about the AWS family of databases, see Databases on AWS on the AWS website.
