Initially conceptualized by Gartner and later expanded upon by AWS, the 7 Rs provide a comprehensive framework for different migration scenarios.
Protegrity’s Approach: Ensuring Data Security as the Foundation for Cloud Migration
Protegrity emphasizes that data security must be the starting point for any cloud migration journey. Without robust data security, businesses face significant challenges in realizing the full potential of cloud innovation.
Rehost
Rehosting, commonly known as “lift and shift,” involves moving applications from the current on-premise environment to the cloud without making significant changes. This approach is ideal for businesses looking for a quick and straightforward migration. The main advantage of rehosting is its speed and simplicity, allowing businesses to migrate quickly with minimal disruption. However, it may not fully leverage the cloud’s capabilities, potentially leading to higher operational costs and inefficiencies.
Relocate
Relocating refers to physically moving IT infrastructure to a different location, which might be necessary for businesses facing data center closures or consolidations. This strategy maintains existing architectures and requires fewer changes, making it a relatively straightforward transition. The primary drawback is that it is limited to scenarios where physical relocation is necessary and can involve downtime during the migration process.
Replatform
Replatforming involves making some optimizations to applications to take better advantage of cloud capabilities without significant changes to the core architecture. This approach offers a balance between speed and performance improvements, making it suitable for businesses looking to enhance efficiency and scalability with moderate effort. While it provides better performance than rehosting, it still requires careful planning and potential adjustments to ensure compatibility and stability.
Refactor
Refactoring, or re-architecting, involves redeveloping applications to fully leverage cloud-native features and services. This strategy is the most complex and resource-intensive but offers the greatest benefits in terms of performance, scalability, and cost efficiency. Refactoring is best suited for businesses committed to long-term cloud optimization and innovation. The high complexity and significant time investment can be challenging, but the rewards include improved agility and reduced operational costs.
Repurchase
Repurchasing involves moving to a new software solution, typically a cloud-based SaaS application, instead of migrating existing applications. This approach is beneficial for businesses looking to adopt modern solutions quickly and with lower upfront costs. The primary advantage is the simplified adoption of new capabilities without the need for extensive migrations. However, it can present challenges related to data migration and the potential loss of customizations from the previous system.
Retire
Retiring involves identifying and decommissioning outdated or unnecessary applications that no longer serve the business’s needs. This strategy helps reduce complexity and costs by streamlining the IT portfolio. It requires careful analysis to ensure that critical systems are not inadvertently retired. The main benefit is the reduction of maintenance overhead and the focus on more valuable applications and services.
Retain
Retaining certain applications on-premise while migrating others to the cloud is known as the hybrid approach. This strategy is useful for businesses that need to maintain control over sensitive data or have applications that are not cloud-compatible. It offers flexibility and allows businesses to transition at their own pace. However, managing a hybrid environment can be complex, requiring robust integration and management solutions to ensure seamless operation.
