**AWS Migration Hub** serves as a central location to track migration progress across multiple AWS and partner solutions. It provides visibility into your application portfolio and monitors the status of migrations.
**AWS Application Migration Service (MGN)** enables lift-and-shift migrations by automatically converting source servers to run natively on AWS. This service minimizes time-intensive and error-prone manual processes.
**AWS Database Migration Service (DMS)** helps migrate databases to AWS quickly and securely. It supports homogeneous migrations (same database engine) and heterogeneous migrations (different database engines). The source database remains operational during migration, reducing application downtime.
**AWS Schema Conversion Tool (SCT)** converts database schemas from one engine to another, making it easier to migrate between different database platforms.
**AWS Snow Family** includes physical devices for large-scale data transfers. Snowcone, Snowball, and Snowmobile help transfer massive amounts of data when network transfer is impractical due to bandwidth limitations or costs.
**AWS Transfer Family** provides fully managed file transfer services supporting SFTP, FTPS, and FTP protocols for moving files into and out of AWS storage services.
**AWS Migration Evaluator** helps build a data-driven business case for AWS migration by analyzing current infrastructure and providing projected costs.
**AWS Application Discovery Service** collects information about on-premises data centers to help plan migration projects.
These services work together as part of the AWS Cloud Adoption Framework (CAF), which provides guidance and best practices for successful cloud migration. Organizations can choose the appropriate combination of services based on their specific migration requirements, timeline, and technical constraints.
AWS Migration Resources and Services
Why AWS Migration Resources Are Important
Migration is a critical component of cloud adoption. Organizations moving from on-premises infrastructure or other cloud providers to AWS need structured tools and services to ensure smooth transitions. Understanding AWS migration resources is essential for the Cloud Practitioner exam as it demonstrates knowledge of how AWS facilitates enterprise cloud adoption.
What Are AWS Migration Resources?
AWS provides a comprehensive suite of migration services designed to help organizations transfer workloads, data, and applications to the cloud efficiently. These resources minimize downtime, reduce risk, and accelerate the migration process.
Key AWS Migration Services
AWS Migration Hub A central location to track the progress of application migrations across multiple AWS and partner solutions. It provides visibility into your migration status and helps coordinate efforts.
AWS Application Migration Service (AWS MGN) The primary recommended service for lift-and-shift migrations. It automates the conversion of physical, virtual, and cloud-based servers to run natively on AWS.
AWS Database Migration Service (DMS) Helps migrate databases to AWS quickly and securely. The source database remains fully operational during migration, minimizing downtime. It supports homogeneous migrations (same database engine) and heterogeneous migrations (different database engines).
AWS Schema Conversion Tool (SCT) Converts database schemas from one database engine to another, typically used alongside DMS for heterogeneous database migrations.
AWS Snow Family Physical devices for large-scale data transfers when network transfer is impractical: - Snowcone: Smallest device, 8-14 TB storage - Snowball Edge: 80 TB storage with compute capabilities - Snowmobile: Exabyte-scale transfer using a shipping container
AWS Transfer Family Enables file transfers into and out of Amazon S3 or EFS using SFTP, FTPS, and FTP protocols.
AWS DataSync Automates and accelerates moving data between on-premises storage and AWS storage services.
How AWS Migration Works
The typical migration process follows these phases:
1. Assess: Evaluate current infrastructure and identify migration candidates 2. Mobilize: Plan the migration, address gaps, and prepare the environment 3. Migrate and Modernize: Execute the migration using appropriate AWS services
Common Migration Strategies (The 7 Rs)
- Rehost: Lift-and-shift to AWS - Replatform: Lift, tinker, and shift with minor optimizations - Repurchase: Move to a different product (often SaaS) - Refactor: Re-architect using cloud-native features - Retire: Decommission unneeded applications - Retain: Keep certain applications on-premises - Relocate: Move to AWS at the hypervisor level
Exam Tips: Answering Questions on AWS Migration Resources
1. Database migrations almost always point to AWS Database Migration Service (DMS). Remember that DMS keeps the source database operational during migration.
2. When questions mention large amounts of data (terabytes to petabytes) and limited bandwidth or slow network connections, think Snow Family devices.
3. Lift-and-shift server migrations typically require AWS Application Migration Service.
4. Questions about tracking migration progress across multiple tools point to AWS Migration Hub.
5. Heterogeneous database migrations (changing database engines) require both DMS and Schema Conversion Tool.
6. For ongoing data synchronization between on-premises and AWS storage, consider AWS DataSync.
7. Remember that Snowmobile is for exabyte-scale transfers and involves a physical shipping container truck.
8. When you see questions about maintaining existing file transfer workflows using FTP or SFTP, the answer is likely AWS Transfer Family.
9. Focus on matching the scale of data and type of workload to the appropriate migration service.
