Services and Strategies

Modern Migration Paradigm

Shift from Server to Workload Migration

• Focus on component-based migration

• Break applications into individual workloads

• Target appropriate AWS services for each component

Common Migration Patterns

1. Containerized Applications

   • Migration to AWS Batch

   • Implementation on AWS Fargate

2. Tomcat Applications

   • Migration to Elastic Beanstalk

   • Reduced operational overhead

   • Automatic scaling capabilities

3. Microservices

   • Migration to event-driven architecture

   • Serverless implementation

   • Message handling optimization

Core Migration Services

Migration Hub

• Centralizes migration planning and tracking

• Integrates with Application Discovery Service

• Provides instance sizing recommendations

• Offers migration strategy advice

• Features intuitive dashboard for progress tracking

Application Discovery Service

Key Features

• Server-application mapping

• Traffic pattern analysis

• Encrypted data transmission

• Visual application mapping

Implementation

1. Agent installation on on-premises servers

2. Production traffic analysis

3. Server relationship mapping

4. Migration strategy development

Application Migration Service (MGN)

Use case 1:

Use case 2:

Capabilities

• Windows and Linux server migration

• Cross-cloud provider support

• Minimal interruption cutover

• Free service (pay only for EC2 instances)

Implementation Process

1. MGN agent installation

2. Continuous block storage replication

3. Test environment staging

4. Production cutover

5. Traffic redirection

Best Practices

Planning Phase

1. Define optimization priorities

2. Assess application components

3. Map dependencies

4. Choose appropriate migration tools

Implementation Phase

1. Install necessary agents

2. Configure monitoring

3. Test migrations

4. Plan cutover strategies

Post-Migration

1. Monitor performance

2. Optimize resources

3. Document configurations

4. Implement backup strategies

Recommendations

1. Focus on workload-specific solutions

2. Utilize AWS managed services when possible

3. Consider hybrid solutions when appropriate

4. Plan for minimal disruption

5. Implement proper testing

6. Document migration processes
