n-premises applications require a transformative approach to help unlock the benefits of the Amazon Web Services (AWS) Cloud. The seven common migration strategies (7 Rs) provide you with transformation options, which vary from making technology changes in on-premises database servers to rebuilding an application by using a cloud-native microservices architecture.
Choosing to use the full 7 Rs model means that you operate at the application and business level instead of only evaluating and preparing the servers for migration. Although you can obtain server data by using tools such as AWS Migration Evaluator, other application information is often not recorded (for example, roadmap status, required recovery time objective (RTO) and recovery point objective (RPO), or data privacy requirements).
This pattern describes how to use AppScore to avoid these challenges by using an application-centric view of your portfolio. This includes a recommended transformation route to the AWS Cloud for each application against the full 7 Rs model. AppScore helps you capture application information, determine the ideal transformation route, identify the risk, complexity and benefits of cloud adoption, and quickly define the migration scopes, move groups, and schedules.
This pattern was created by AWS and AppScore Technology Limited, an AWS Partner.
