The company migrates the transaction Data from the on-premises database to AWS at the end of each month. The company has noticed that the cost to migrate data from the onpremises Database to an Amazon RDS for SQL Server database has increased recently. The company requires a cost-effective solution to migrate the data to AWS. The solution must cause minimal downtown for the applications That access the database. Which AWS service should the company use to meet these requirements?

• A. AWS Lambda
• B. AWS Database Migration Service (AWS DMS) ✓
• C. AWS Direct Connect
• D. AWS DataSync

Correct Answer: B. AWS Database Migration Service (AWS DMS)

Explanation

答案B正确。AWSDatabaseMigrationService(AWSDMS)是专门为在不同数据库之间进行数据迁移而设计的服务，能够以成本有效的方式完成数据迁移任务。它可以在尽量减少应用程序停机时间的情况下实现数据的迁移，符合公司要求成本效益高且对应用程序影响最小的需求。选项A的AWSLambda主要用于无服务器计算，不太适用于大规模的数据迁移。选项C的AWSDirectConnect主要用于建立专用网络连接，并非针对数据迁移。选项D的AWSDataSync虽然也用于数据同步，但在处理从本地SQLServer到AmazonRDSforSQLServer数据库的迁移时，可能不如AWSDMS适用。综上所述，选择B选项。
