Question #568
A company is planning to migrate its on-premises Linux and Windows workloads to AWS. The company's infrastructure includes bare-metal servers and virtual machines hosting a variety of applications. The company needs to capture system configurations, performance metrics, active processes, and network connections of its on-premises workloads. Additionally, the company must organize its applications into migration groups and obtain Amazon EC2 instance recommendations to ensure cost-effective operation on AWS.
Which combination of steps should a solutions architect take to meet these requirements? (Choose three.)
Assess the on-premises workloads by deploying AWS Application Discovery Agent on the bare-metal servers and virtual machines.
Assess the on-premises workloads by deploying AWS Systems Manager Agent on the bare-metal servers and virtual machines.
Organize servers into migration groups by using AWS Systems Manager Application Manager.
Organize servers into migration groups by using AWS Migration Hub.
Generate suggested EC2 instance types and associated pricing by using AWS Migration Hub.
Import server sizing data into AWS Trusted Advisor and implement its cost-optimization recommendations.
Explanation
The correct answers are A, D, and E. Here's why:
- A: AWS Application Discovery Agent is specifically designed to collect system configurations, performance metrics, processes, and network connections from on-premises servers (both bare-metal and VMs) for migration planning. This aligns with the requirement to capture workload details.
- D: AWS Migration Hub allows organizing discovered servers into migration groups, enabling structured planning and tracking of application migrations.
- E: Migration Hub generates EC2 instance recommendations based on collected data, ensuring cost-effective resource allocation.
Why other options are incorrect:
- B: Systems Manager Agent (SSM) is used for post-migration management, not data collection for migration planning.
- C: Systems Manager Application Manager manages applications post-migration but does not organize migration groups.
- F: Trusted Advisor provides general cost-optimization tips but does not process server sizing data for EC2 recommendations.
Key Points:
1. Use AWS Application Discovery Service (Agent) for migration assessment.
2. Use Migration Hub for grouping servers and generating EC2 recommendations.
3. Avoid mixing migration-specific tools (Discovery Agent, Migration Hub) with post-migration tools (SSM, Trusted Advisor).
Answer
The correct answer is: ADE
