Tutorial / Cram Notes
Migration assessment and tracking tools play a crucial role in the cloud migration process. When preparing for the AWS Certified Solutions Architect – Professional (SAP-C02) exam, understanding the functionality and application of AWS Migration Hub is essential. This tool effectively serves as a central location where you can track the progress of application migrations across multiple AWS and partner solutions.
Features of AWS Migration Hub
AWS Migration Hub provides several features that simplify the process of migration. These include:
Discovery and Assessment:
AWS Migration Hub integrates with tools like AWS Application Discovery Service, which helps in the identification of on-premises workloads and their dependencies. This step is vital in planning the migration and ensures that nothing is overlooked.
Migration Tracking:
The ability to track the status of your migrations across multiple AWS solutions and partner tools from a central hub removes the complexity of using multiple tracking tools. Migration Hub provides a summary view that shows the status of the migrations in progress and those that are completed.
Application Grouping:
You can group your servers and applications into what AWS calls “application groupings”. This helps in understanding the collective migration status of related resources, making it easier to manage and coordinate the migration process.
Integrate Third-party Tools:
AWS Migration Hub allows integrations with various third-party migration tools like CloudEndure Migration and others, providing flexibility in choosing the migration strategy that fits your needs.
Example of AWS Migration Hub in Action
Example Scenario:
A company plans to migrate its web application from an on-premises data center to AWS. The application consists of a front-end, a database server, and various middleware components each running on separate servers.
Step 1: Discovery
The company uses AWS Application Discovery Service to gather information about on-premises servers. The following pseudocode-like commands could initialize the discovery process:
start-discovery:
input:
– server-details-list
output:
– discovered-server-details
Step 2: Grouping Applications
Once the discovery data is gathered and available in AWS Migration Hub, the company groups the relevant servers that constitute the whole application:
create-application-grouping:
application-name: “CompanyWebApp”
server-ids:
– srv-front-end
– srv-db
– srv-middleware
Step 3: Tracking Progress
As the company starts the migration using AWS Server Migration Service (SMS) for virtual machines, AWS DMS (Database Migration Service) for databases, and manual lifting and shifting for some components, they send the status updates to Migration Hub:
track-migration-progress:
migration-tools:
– AWS-SMS
– AWS-DMS
application-grouping: “CompanyWebApp”
status-report:
– “in-progress”
Step 4: Monitoring
The migration team monitors the progress through Migration Hub’s Dashboard and assesses if the migration processes are going smoothly:
view-migration-dashboard:
input:
– application-grouping “CompanyWebApp”
response:
– graphical-dashboard
At any point, Migration Hub provides detailed status updates and timelines for each of the grouped application’s services, ensuring that the teams are aware of migration outcomes and timeframes.
Comparison with Other Tools:
To fully appreciate AWS Migration Hub, it is helpful to compare it with other migration assessment tools. Here’s a simplified comparison table:
| Feature | AWS Migration Hub | Other Migration Tools |
|---|---|---|
| Centralized Tracking | Yes | Varies |
| AWS Service Integration | High | Moderate to Low |
| Partner Ecosystem | Extensive | Varies |
| Cost | Pay for underlying services used | Generally have separate costing models |
| Usability | User-friendly centralized interface | Often multiple interfaces |
| Customizable Workflows | Yes | Varies |
It is evident that AWS Migration Hub is designed to offer a seamless, integrated, and centralized migration experience, especially when operating within the AWS ecosystem.
