Key Migration Strategies (The 6 Rs)
When planning your `aws migration steps`, it's essential to select the appropriate strategy for each application. AWS defines six common migration strategies, often called the "6 Rs," which guide decision-making based on business value and technical complexity. Choosing the right "R" is a critical part of the `aws migration steps guide`.
- Rehost (Lift & Shift): This involves moving applications as-is from on-premises to AWS without making any changes. It's typically the fastest and often the first step in large-scale migrations, offering quick time-to-value. This strategy is ideal for quickly getting applications into the cloud and can be part of the initial `deployment process`.
- Replatform (Lift, Tinker, and Shift): This strategy involves making a few cloud-native optimizations to realize some cloud benefits without significantly changing the application's core architecture. An example might be migrating a database from on-premises to a managed AWS service like Amazon RDS. This offers more benefits than rehosting without the full complexity of re-architecting.
- Refactor/Rearchitect: This involves reimagining how an application is architected and developed, typically leveraging cloud-native features for increased agility, scalability, and resilience. This strategy delivers the most significant benefits but requires the most effort and investment. It represents a deeper `implementation steps` change to fully embrace cloud capabilities.
- Repurchase (Drop & Shop): This means moving from a traditional application to a software-as-a-service (SaaS) solution available on AWS or elsewhere. For example, replacing an on-premises CRM system with Salesforce. This can be one of the simplest `procedural steps` if a suitable SaaS option exists.
- Retire: This strategy involves identifying applications that are no longer needed or providing business value and simply decommissioning them. This reduces the footprint and costs of the migration. This step helps streamline the overall `workflow` by removing unnecessary components.
- Retain: This strategy involves keeping some applications on-premises or in their current environment, either due to regulatory requirements, technical complexity, or lack of immediate business value in migrating them. This is an important consideration in the `execution plan` to ensure focus on high-priority migrations.
The choice among these strategies depends on factors like application criticality, technical complexity, budget, and business objectives. A detailed analysis during the Assess phase helps determine the `best aws migration steps` for each workload, ensuring a tailored `migration methodology`. Many organizations will use a mix of these strategies across their application portfolio.
