Migration Hub offers several key capabilities:
**Centralized Tracking**: It aggregates migration status from various AWS migration tools including AWS Application Migration Service (MGN), AWS Database Migration Service (DMS), and AWS Server Migration Service (SMS). This unified view eliminates the need to switch between multiple consoles.
**Application Discovery**: Integration with AWS Application Discovery Service allows you to collect and present configuration, usage, and behavior data from on-premises servers. This helps in planning migrations by understanding server dependencies and utilization patterns.
**Application Grouping**: You can logically group servers and databases into applications, making it easier to track migration progress at the application level rather than individual resources. This is particularly valuable for complex multi-tier applications.
**Migration Status Visibility**: The service provides real-time status updates showing which servers are not started, in progress, or completed. This visibility helps project managers and architects identify bottlenecks and adjust resources accordingly.
**Home Region Selection**: Migration Hub requires you to select a home region where all migration tracking data is stored. This region should be chosen based on data residency requirements and team location.
**Partner Tool Integration**: Beyond AWS native tools, Migration Hub integrates with third-party migration solutions from partners like CloudEndure, Atadata, and RiverMeadow, providing flexibility in tool selection.
**Cost Considerations**: Migration Hub itself is offered at no additional charge - you only pay for the underlying migration tools and resources used during the migration process.
For large-scale migrations, Migration Hub becomes indispensable for maintaining visibility, ensuring accountability, and demonstrating progress to stakeholders throughout the migration journey.
AWS Migration Hub - Complete Guide for AWS Solutions Architect Professional
Why AWS Migration Hub is Important
AWS Migration Hub is critical for organizations undertaking cloud migration projects because it provides a single location to track the progress of application migrations across multiple AWS and partner solutions. Without centralized tracking, migration projects can become chaotic, with teams losing visibility into which workloads have been moved, which are in progress, and which are pending. For the Solutions Architect Professional exam, understanding Migration Hub demonstrates your ability to architect enterprise-scale migration strategies.
What is AWS Migration Hub?
AWS Migration Hub is a service that provides a central dashboard to track and manage migrations to AWS. It aggregates migration status from various migration tools into one unified view.
Key Components: - Migration Hub Console: Central dashboard for viewing all migrations - Home Region: A single region where all migration tracking data is stored - Application Discovery: Integration with AWS Application Discovery Service - Migration Tracking: Status updates from integrated tools - Application Grouping: Logical grouping of servers into applications
How AWS Migration Hub Works
1. Set Up Home Region: You must first select a home region where all your migration tracking data will be stored. This cannot be changed once set, so choose carefully based on compliance and proximity requirements.
2. Discovery Phase: Use AWS Application Discovery Service or partner tools to discover on-premises servers, applications, and dependencies. This data feeds into Migration Hub.
3. Group Applications: Organize discovered servers into logical application groups. This allows you to track migrations at the application level rather than individual server level.
4. Connect Migration Tools: Migration Hub integrates with: - AWS Server Migration Service (SMS) - AWS Database Migration Service (DMS) - CloudEndure Migration - AWS Application Migration Service (MGN) - Partner migration tools (Atadata, RISC Networks, etc.)
5. Track Progress: As migrations proceed, tools send status updates to Migration Hub. You can view progress across all applications and servers from the central console.
Key Features to Remember:
- Agentless or Agent-based Discovery: Supports both methods through Application Discovery Service - Cross-Account Tracking: Can track migrations across multiple AWS accounts using AWS Organizations - No Additional Cost: Migration Hub itself is free; you pay only for the migration tools used - Strategy Recommendations: Migration Hub Strategy Recommendations helps analyze your portfolio and suggest migration strategies (rehost, replatform, refactor, etc.)
Exam Tips: Answering Questions on AWS Migration Hub
Tip 1: Remember the Home Region Concept Migration Hub requires selecting ONE home region. All tracking data is stored there. Exam questions may test whether you understand this single-region limitation.
Tip 2: Know the Integration Points When questions mention tracking migrations from multiple tools or needing a unified view, Migration Hub is likely the answer. It integrates with DMS, SMS, MGN, and CloudEndure.
Tip 3: Distinguish from Individual Migration Services Migration Hub does NOT perform migrations itself. It only tracks them. If a question asks about actually moving data or servers, look for DMS, SMS, or MGN as answers.
Tip 4: Application-Centric View If questions emphasize tracking migrations at the application level rather than individual servers, Migration Hub is the correct choice.
Tip 5: Strategy Recommendations Use Case When questions ask about analyzing an application portfolio to determine the best migration strategy (6 Rs), think of Migration Hub Strategy Recommendations.
Tip 6: Cost Considerations Migration Hub itself has no cost. This may be tested in scenarios comparing solutions.
Tip 7: Multi-Account Scenarios For enterprise scenarios involving multiple AWS accounts and organizations, remember Migration Hub supports cross-account tracking.
Common Exam Scenarios: - Enterprise needs single dashboard for migration visibility → Migration Hub - Track DMS and SMS migrations together → Migration Hub - Analyze portfolio for migration strategy → Migration Hub Strategy Recommendations - Discover on-premises dependencies → Application Discovery Service + Migration Hub
