Rehost vs Replatform vs Re-architect

Choosing the right cloud migration strategy is essential for a successful transition. Rehost, Replatform, and Re-architect each offer unique benefits and are suited for different needs. Here’s a brief overview to help you decide.

Rehost
Rehosting, or “lift-and-shift,” involves moving applications to the cloud with minimal changes. It replicates your existing setup on cloud platforms, allowing for a quick migration. This approach is ideal for businesses seeking to migrate rapidly and cost-effectively without altering application architecture. However, it might not fully exploit cloud-native features, which can lead to suboptimal performance.

Replatform
Replatforming involves minor modifications to enhance applications for the cloud without complete redesigns. This strategy allows businesses to adjust components like databases or middleware to utilize cloud services. Replatforming offers a balance between rehosting and re-architecting, providing improved performance and cost-efficiency while retaining core functionalities.

Re-architect
Re-architecting requires redesigning applications to fully utilize cloud-native features. This approach embraces advanced cloud capabilities like microservices and serverless computing, offering the most significant potential for optimization. Re-architecting is best for organizations looking to achieve maximum performance and scalability, though it demands more time and resources.

Choosing the Right Strategy
Selecting a strategy depends on your goals, infrastructure, and budget:

• Rehost: Quick and cost-effective for minimal changes.
• Replatform: Offers moderate changes for better optimization.
• Re-architect: Best for complete transformation and innovation.

Ultimately, the right approach aligns with your organization’s long-term vision and current needs. Cloud migration experts can help you evaluate your options and execute a migration strategy that delivers tangible business benefits.
