Application Migration to the Cloud with AWS

Migrating your existing application to the cloud using AWS can help your team modernize your infrastructure and improve scalability.

Cloud migration is the process of moving data, applications, and other business elements from on-premises infrastructure to the cloud. AWS provides several tools and services to make this process easier.

The 6 R's of Migration

AWS recommends considering these six migration strategies:

1. Rehosting (Lift and Shift): Moving applications without changes
2. Replatforming: Making a few cloud optimizations without changing core architecture
3. Repurchasing: Moving to a different product (often SaaS)
4. Refactoring: Re-architecting the application to be cloud-native
5. Retire: Getting rid of applications no longer needed
6. Retain: Keeping certain applications on-premises

AWS Migration Services

AWS Migration Hub

A single location to track the progress of application migrations across multiple AWS and partner solutions.

AWS Application Migration Service

The primary migration service recommended for lift-and-shift migrations. It automatically converts your source servers to run natively on AWS.

AWS Database Migration Service

Helps you migrate databases to AWS quickly and securely while keeping the source database operational during the migration.

Best Practices

• Start with a thorough assessment of your current environment
• Begin with less critical applications to gain experience
• Use AWS Well-Architected Framework as a guide
• Plan for security and compliance from the start
• Test thoroughly before and after migration
