R’s Of Cloud Migration

R’s Of Cloud Migration 

Broadly categorized as the “six R’s of migration,” these strategies offer various approaches, each tailored to different business needs and priorities. Understanding and choosing the right strategy is crucial for a successful transition to the cloud.

  • Rehosting (“Lift and Shift”)

Rehosting involves lifting your existing infrastructure and shifting it from on-premises hosting to the cloud without making significant modifications. This approach aims for a quick return on investment (ROI) by creating an exact replica of the current environment. It is suitable for companies with a conservative culture or those lacking a long-term strategy for advanced cloud capabilities. The advantage of rehosting lies in its simplicity and speed, making it an efficient strategy for organizations looking for a straightforward migration process.

  • Replatforming

Replatforming, a variation of lift and shift, involves making additional adjustments to optimize your applications for the cloud. While the core architecture remains the same, organizations implementing this strategy aim to enhance performance and efficiency. Replatforming is a good fit for conservative organizations seeking to build trust in the cloud while realizing benefits like increased system performance. It strikes a balance between the simplicity of rehosting and the potential improvements offered by more complex strategies.

  • Repurchasing

Repurchasing entails moving applications to a new, cloud-native product, commonly a Software as a Service (SaaS) platform. For example, migrating a Customer Relationship Management (CRM) system to Salesforce. This strategy can be cost-effective, especially for organizations transitioning from highly customized legacy landscapes. However, it comes with challenges, such as adapting to a new platform and training teams on its usage. Repurchasing is a strategic move for organizations looking to benefit from specialized cloud services provided by third-party vendors.

  • Refactoring (Rearchitecting)

Refactoring, or rearchitecting, involves rebuilding applications from the ground up. This strategy is driven by the need to leverage cloud capabilities not available in the existing environment, such as auto-scaling or serverless computing. While refactoring is generally the most expensive option, it offers compatibility with future versions and allows organizations to fully exploit advanced cloud features. Businesses adopting this strategy prioritize long-term benefits and are willing to invest in overhauling their applications for maximum cloud efficiency.

  • Retiring

After assessing the application portfolio for cloud readiness, organizations may find some applications are no longer useful or relevant. In such cases, the retirement strategy involves simply turning off these applications. The resulting cost savings can potentially strengthen the business case for migrating other applications. This approach is a pragmatic way to streamline the IT landscape, focusing resources on essential and relevant applications, ultimately contributing to cost efficiency and improved overall performance.

  • Retaining

Not all organizations are ready for or find value in immediate cloud adoption. The retaining cloud strategy acknowledges that cloud migration might not currently align with the organization’s priorities or constraints. This could be due to compliance reasons, data sensitivity concerns, or a recent application upgrade. In such cases, organizations plan to revisit cloud computing at a later date when it makes more business sense. Retaining allows businesses to migrate to the cloud at their own pace, aligning with their strategic goals and priorities.
