• Consider factors such as cost, scalability, security features, and geographic location.
• Evaluate their support and documentation resources.
• Check for specific ecommerce-focused solutions and services.
• Explore hybrid cloud options if necessary.

1.3 Defining Migration Strategy

• Rehost (lift and shift): Migrate your existing applications and data without significant changes.
• Replatform: Migrate to a cloud-based platform with minimal code changes.
• Refactor: Refactor your applications to leverage cloud-native services.
• Repurchase: Replace your existing applications with cloud-based SaaS solutions.
• Rearchitect: Completely redesign your application architecture for the cloud.
• Develop a detailed migration plan with timelines and milestones.

1.4 Risk Assessment and Mitigation

• Identify potential risks such as downtime, data loss, and security breaches.
• Develop mitigation strategies for each identified risk.
• Establish a robust rollback plan in case of unforeseen issues.
• Ensure compliance with relevant regulations and industry standards.

Phase 2: Migration Execution

2.1 Data Migration

• Develop a data migration strategy, including data cleansing and validation.
• Choose appropriate data migration tools and techniques.
• Implement a phased approach to minimize disruption.
• Thoroughly test the migrated data for accuracy and completeness.
• Establish data backup and recovery procedures.

2.2 Application Migration

• Migrate your ecommerce applications to the chosen cloud platform.
• Configure and optimize the applications for cloud performance.
• Implement monitoring and logging to track application health and performance.
