What is a Cloud Migration Strategy?
Cloud migration strategy is an elaborate plan that describes the steps that a company needs to take to move its data, apps and infrastructure from on-premises or legacy systems to a cloud environment. Some businesses may choose to run their own private cloud, but the most frequent approach is to use a public cloud via a provider.
6 R’s of Cloud Migration
The 6 R’s framework gives you six different options for transferring your apps. Each “R” symbolizes a different method, and you will likely employ a combination of ways for your migration effort.
|
Rehost |
Rehosting is simply shifting your applications to the cloud without any changes. In effect, you take them out of your existing environment and put them into the cloud infrastructure. This is the quickest and easiest method. |
|
Replatform |
When you replatform your app you make modest adjustments without disrupting the basic design of the app. You may make it more portable by moving to a managed database provider or containerizing your software. This is a way to gain some of the benefits of the cloud without a complete re-think, which can be hard to execute. |
|
Refactor |
As you refactor, you re-architect your apps to take use of all the cloud-native features they offer. You can break a single app into smaller sections called microservices, or you can go with serverless solutions. This approach involves the greatest time and technical know-how but offers the most long-term advantages. |
|
Repurchase |
When you buy again, you are replacing the app that you are using with a cloud-based one, generally a SaaS alternative. For example, rather than migrating your on-premises CRM, you may go to Salesforce. This way you save on maintenance costs and immediately get new features. |
|
Retire |
Not all things have to be in motion. Some apps are now at the end of their functional life or have been replaced by newer systems. Retiring these apps will simplify and decrease expense. Use the migration process as an opportunity to audit your entire application portfolio. |
|
Retain |
Some applications will have to remain where they are, at least for now. Perhaps they have compliance needs that make cloud migration more difficult, or they’re on the chopping block. Retaining does not mean never migrating, but waiting for the proper time to migrate. |

Steps in Cloud Migration Strategy
Understand Business Goal
The first and most critical stage is to clarify the reason for migrating to the cloud. Knowing why individuals are doing what they’re doing and what they want to happen can help leaders and partners agree on goals.
Select the Cloud Provider
Choose the right cloud destination, set up permission controls, and decide what is most important in your migration. Based on your goals and what you're migrating first, you can also outline a general schedule for the migration.
Develop Migration Strategy
Identify the best migration type that fits the characteristics, business objectives, and technological restrictions for all relevant applications. Most people Rehost, Refactor, Replatform or Replace while migrating.
Development of Proof of Concept (PoC)
Run a proof of concept test of the migration plan and assumptions, with some work that is similar to what is already there. Define success metrics (KPIs), e.g. application response time, utilization of resources or cost savings.
Build a Detailed Migration Plan
Detailed Migration Plan based on Collected Data from Previous Steps. It should also list the migration teams involved, any automation tools required, risk management and a testing strategy for a successful move.7.
Run the Migration
Implement the migration plan, paying close attention to progress. Communication channels must be open to keep stakeholders informed of the project’s progress and to be available to address any concerns that may emerge. The last stage is to collect information on application performance and usage.
Review & Optimize
Once the migration is complete, review accomplishments and failures against the original strategy, business objectives and KPIs. Analyze data collected during migration to find chances for optimization. Cloud Computing Classes in Pune help you in developing the right skill to become a professional in this domain.
