AWS Cloud Migration Guide: A Step-by-Step 7 Rs Strategy Walk-through

Migrating your on-premises systems to the cloud is exciting and intimidating for us at Trawlii. With AWS Cloud Migration, you can modernize your infrastructure, save on costs, and enhance agility. Here, we will outline our strategy for AWS migration based on the well-proven 7 Rs of cloud migration. Whether you're considering a quick lift and shift cloud migration or something deeper, our experience will help you determine the best path. 

Our Cloud Migration Expertise 

When our clients come to us, they are typically lost as to how to transition away from legacy on-premises infrastructure to the cloud. In the time we've been at Trawlii, we've learned that there is no single solution. Instead, it is in understanding and selecting from the seven distinct strategies that make up the 7 Rs methodology. It has been our beacon, our guide, leading us and our clients through choices of what applications to rehost, replatform, refactor, repurchase, relocate, retain, or retire. 

The 7 Rs of Cloud Migration Strategies 

1. Rehost ("Lift and Shift") : Rehost—also known as lift and shift cloud migration—is migrating your apps from on-premises servers to AWS with little or no modification. It's a simple method that many of our clients choose when they need to go fast.   

Benefits: 

• Fast and simple 
• Less disruption 
• Immediate access to AWS benefits 
• Best For: Reliable legacy systems that are expensive to maintain on-premises 

2. Replatform ("Lift, Tinker, and Shift") : Replatforming is about making small adjustments—such as relocating to a managed service like Amazon RDS—while migrating your application. It's akin to purchasing a new home and rearranging your furniture to accommodate your lifestyle now. 

Advantages: 

1. Improved performance with minimal adjustment.
2. Catches some cloud-native benefits without a full rebuild 

Best For: Applications that need small changes to improve efficiency 

3. Refactor / Re-architect : For some high-value or complex applications, refactoring—or re-architecting—is the best answer. Refactoring involves restructuring the application to maximize the use of AWS capabilities, like remodeling your home to better fit modern living. 

Benefits: 

1. Maximizes scalability and resilience.
2. Compliant with modern architectures like microservices or serverless computing 

Best For: Mission-critical applications that need to transform to support future growth 

4. Repurchase ("Drop and Shop") : Repurchasing involves replacing an older app with a fresh, cloud-native one—most often in the guise of a SaaS solution. It is akin to replacing an old car with a new, better model.  

Benefits: 

1. Reduces maintenance costs.
2.  Reduces time-to-value through the deployment of a well-known good solution 

Optimally Used For: Situations where there is a superior off-the-shelf solution 

5. Relocate: Relocate is particularly suited to VMware-using organizations. This approach allows you to move all workloads to AWS without impacting most of your existing infrastructure. 

Benefits: 

1. Smooth transition with minimal disruption.
2.  Maintains existing familiar systems while leveraging cloud benefits 

Suitable For: Large VMware investment firms 

6. Retain ("Revisit"): Sometimes, it is best to leave some applications on-premises temporarily. Retaining allows you to delay migration until the appropriate time, just as you would hold onto a family heirloom until you can give it away in an appropriate way. 

Benefits: 

1. Avoids unnecessary costs.
2. Provides stability for mission-critical applications 

Best For: Applications with extreme regulatory or technical needs 

7. Retire: Retiring involves shutting down apps that no longer have a business function. It's a kind of cleaning out your closet to make space for new possibilities. 

Advantages: 

1. Saves on maintenance and operational expenses.
2.  Simplify your IT landscape.

Best For: Old or duplicate systems that don't contribute value anymore .

Picking the Right Model

At Trawlii, we think that the ideal migration model relies on your specific business objectives, technology requirements, and budget. Reflect on these important points while making your decision: 

• Business Objectives: Do you prefer a quick move to save dollars, or do you prefer a change that will last? 
• Application Complexity:  How well is your application coupled with other systems? Do you simply need a rehost, or do you need a whole refactor?
• Budget: A lift and shift cloud migration might cost less initially, but a refactor can reward you in the long term. 
• Technical Requirements: You might need to consider licensing, compliance, and hardware dependencies that might affect your move. 

By closely analyzing these factors, we can help you map the right AWS migration strategy with your business needs.
