Select workloads for migration, determine optimal migration approaches, architect new solutions for existing workloads, and identify modernization opportunities (~20% of exam).
Covers selecting existing workloads for potential migration including migration assessment and tracking tools (Migration Hub), portfolio assessment, asset planning, prioritization and wave planning, completing application migration assessments, evaluating applications with 7Rs migration strategies, and evaluating total cost of ownership (TCO). Also covers determining optimal migration approaches including data migration tools (DataSync, Transfer Family, Snow Family, S3 Transfer Acceleration), application migration tools (Application Discovery Service, Application Migration Service), networking services and DNS (Direct Connect, Site-to-Site VPN, Route 53), identity services (IAM Identity Center, Directory Service), database migration tools (DMS, SCT), governance tools (Control Tower, Organizations), selecting appropriate transfer mechanisms, and applying security methods to migration tools. Also covers determining new architecture for existing workloads including compute services (EC2, Elastic Beanstalk), containers (ECS, EKS, Fargate, ECR), storage services (EBS, EFS, FSx, S3, Storage Gateway), and databases (DynamoDB, OpenSearch, RDS, self-managed databases). Finally covers modernization and enhancement opportunities including serverless compute (Lambda), containers, purpose-built databases (DynamoDB, Aurora Serverless, ElastiCache), integration services (SQS, SNS, EventBridge, Step Functions), identifying opportunities for decoupling, serverless solutions, and appropriate service selection for containers and databases.

AWS Accelerate Workload Migration and Modernization refers to a comprehensive approach for moving and transforming applications from on-premises environments to AWS cloud infrastructure while optimizing them for cloud-native capabilities.
The migration process typically follows the 7 Rs framework: Rehost (lift-and-shift), Relocate, Replatform, Refactor, Repurchase, Retire, and Retain. Each strategy addresses different application requirements and business objectives.
Key AWS services supporting migration include:
**AWS Migration Hub** - Provides a central location to track migration progress across multiple AWS and partner solutions.
**AWS Application Migration Service (MGN)** - Enables lift-and-shift migrations by replicating source servers into AWS for non-disruptive testing and cutover.
**AWS Database Migration Service (DMS)** - Facilitates database migrations between homogeneous and heterogeneous database platforms with minimal downtime.
**AWS Schema Conversion Tool (SCT)** - Converts database schemas and code to make them compatible with target databases.
Modernization involves transforming legacy applications to leverage cloud-native services such as containers (Amazon ECS, EKS), serverless computing (AWS Lambda), and managed databases (Amazon Aurora, DynamoDB).
**Best Practices:**
1. Conduct thorough application portfolio assessment using AWS Migration Evaluator
2. Establish a landing zone with AWS Control Tower for governance
3. Implement incremental migration waves to reduce risk
4. Use AWS Application Discovery Service to gather on-premises inventory data
5. Leverage AWS Mainframe Modernization for legacy mainframe workloads
**Benefits include:**
- Reduced operational overhead
- Improved scalability and elasticity
- Enhanced security posture
- Cost optimization through right-sizing
- Faster time-to-market for new features
Organizations should develop a migration factory approach with repeatable processes, automation, and standardized templates to accelerate large-scale migrations while maintaining quality and minimizing business disruption throughout the transformation journey.AWS Accelerate Workload Migration and Modernization refers to a comprehensive approach for moving and transforming applications from on-premises environments to AWS cloud infrastructure while optimizing them for cloud-native capabilities.
