7 Cloud Migration Strategies
There are seven cloud migration strategies: rehosting, redeployment, repackaging, refactoring, repurchasing, retiring, and retaining. These were originally called the “5 Rs” by Gartner and later expanded to “7 Rs”.
Organizations looking to migrate to the cloud should consider which migration strategy best answers their needs. The following is a brief description of each:
1. Refactor/Re-architect – Modifying or redeveloping parts of an application to take advantage of cloud-native features for improved scalability, performance, and resilience.
2. Replatform (Lift and Reshape) – Transferring applications to a cloud platform with minor adjustments, but without changing the core architecture, to better harness cloud capabilities.
3. Repurchase (Drop and Shop) – Moving to a new product or service, typically opting for a cloud-native solution rather than migrating the existing one.
4. Rehost (Lift and Shift) – Directly moving applications and data to the cloud without any modification, essentially a ‘copy-paste’ approach.
5. Relocate (Hypervisor-Level Lift and Shift) – Transfer virtual machine images from an on-premises hypervisor to a cloud-based one, keeping the applications unchanged.
6. Retain (Revisit) – Choosing to keep certain applications or systems in their current environment, postponing the migration decision for later evaluation.
7. Retire – Identifying and discontinuing the use of redundant or unneeded resources instead of migrating them to the cloud.
How Does the Cloud Migration Process Work?
The process of partially or completely transferring a company’s digital assets, services, databases, IT resources, and applications to the cloud is known as cloud migration. There are various steps in the procedure:
Step 1. Assessment
Evaluate the existing on-premises data center, applications, and workloads to understand the requirements and challenges. An e-commerce company assesses its customer database and transaction processing system, identifying dependencies and estimating the workload to be moved, ensuring a seamless shopping experience post-migration.
Step 2. Planning and Roadmap
Develop a comprehensive cloud migration strategy and roadmap detailing the steps, timeline, resources, and potential risks. The e-commerce company devises a plan to adopt a multi-cloud approach, selecting suitable cloud services and providers, establishing timelines, and allocating resources, ensuring the chosen strategy aligns with business goals and customer needs.
Step 3. Migration Execution
Move the applications and data to the selected cloud environment, ensuring secure and efficient transfer with minimal downtime. The company executes the migration of its customer database and transaction processing system, employing secure data transfer protocols and validating successful data transfer, aiming for uninterrupted business operations.
