SAP-C02 Question 593
Select 3A company is planning to migrate its on-premises data center to AWS within a short timeline. The applications are a mix of legacy systems and modern architectures, and the company wants to ensure minimal downtime while maintaining data consistency during the migration. Which combination of AWS services should the company use to achieve these objectives?
- A
AWS Application Discovery Service to identify dependencies and usage patterns of on-premises applications
- B
AWS Application Migration Service to replicate on-premises servers and convert them to run natively on AWS
- C
AWS Database Migration Service (DMS) to migrate databases with minimal downtime
- D
AWS Snowball to transfer data physically for all applications
- E
AWS Elastic Disaster Recovery (AWS EDR) to test failover and recovery for migrated applications
Show answer and explanation
Correct answers: A, B, C
Explanation
The combination of AWS Application Discovery Service, AWS Application Migration Service, and AWS Database Migration Service (DMS) provides a comprehensive solution for migrating on-premises applications and databases to AWS. Application Discovery Service aids in planning by identifying dependencies and resource usage, Application Migration Service ensures minimal downtime for server migrations, and DMS ensures data consistency during database migration. AWS Snowball and AWS Elastic Disaster Recovery are not directly relevant to this use case, as Snowball is for physical data transfer, and Elastic Disaster Recovery focuses on disaster recovery rather than migration.
- A. Correct.
AWS Application Discovery Service helps identify on-premises application dependencies and resource utilization, which is crucial for planning a migration strategy.
- B. Correct.
AWS Application Migration Service simplifies the migration of on-premises servers to AWS by continuously replicating server data and converting it to run natively on AWS with minimal downtime.
- C. Correct.
AWS Database Migration Service (DMS) is designed to migrate databases efficiently, ensuring minimal downtime and data consistency during the migration.
- D. Incorrect.
AWS Snowball is primarily used for transferring large amounts of data physically. While useful for some migrations, it is not suitable for applications requiring continuous data replication or minimal downtime.
- E. Incorrect.
AWS Elastic Disaster Recovery (AWS EDR) is designed for disaster recovery scenarios, not for the primary migration of applications. It is useful after applications are migrated to test failover and recovery processes.
