Overview
Nowadays, most businesses, from small to large, are moving to the cloud platform. AWS provides a wide range of cloud services that help companies to set up and launch fast.
This blog will discuss AWS cloud migration strategies and best practices for businesses to migrate to the cloud with less interruption.
AWS Cloud Migration Strategies
- Rehost (lift and shift): With this strategy, we can move applications from your on-premises application to AWS Cloud without modifying the application. It is mostly used for large-scale applications. It also reduces cost, minimum effort and has better compliance and security.
The use case of rehost is like we move any application from any other cloud platform to AWS.
- Replatform (lift, tinker, and shift): It is similar to rehosting, but moving to the cloud makes some optimal changes to work more efficiently or optimally. It takes advantage of the cloud environment. It optimizes the performance, but it takes more time than rehosting.
The use case for the platform is like you migrate your on-premises Oracle database to Amazon RDS for Oracle in the AWS Cloud.
- Repurchase: This strategy is also called drop and shop. In this, we replace your application with a new product or version. It gives more benefits like accessibility and a pay-as-you-go model and reduces licensing and maintenance costs. If we replace them with third-party equivalents, we can get new features and services they provide.
The use case for repurchasing is like Swapping a self-built VPN server for a vendor-built appliance.
- Refactor: With this strategy, we move the application by modifying its architecture or restructuring code. Still, the functionality will not be changed if the changes are made without changing its external behavior. It is like rearchitecting the structure.
The use case of refactoring is like updating the old code, adding new features, and improving code quality.
- Retire: This is the strategy for the application you want to archive or decommission, which means you want to migrate only that is being used, not that which is not used. Removing the components means archiving and shutting down, and it does not affect business operations.
The Use case of retire is if replacing a legacy system helps reduce maintenance costs and improves system performance.
- Retain (revisit): This strategy means that you want to keep on your source environment for some of your applications that you do not want to migrate. So, we can use this if we want to migrate. Some cases, like dependencies and no business value to migrate, can be retained.
The use cases of retain can be used for updating migration plans, optimizing costs, and ensuring compliance and scalability concerns.

Best Practices for Cloud Migration
- Develop a migration plan: A structured plan should be made for a successful migration to the cloud, including scope, timeline, resource allocation, and what risks can occur during migration and its solution.
- Choose the right AWS Service: AWS provides many services, and for migration, we need to select the right service based on our needs.
- Validate the security of your data: Data security must be the main priority in migration. Data should be encrypted in both ways in rest and transit.
- Testing and validation: Testing can be performed before migration to the staging environment so that if any issue occurs, we can validate and can resolve it.
- Monitoring and Optimize: After the AWS service is available, we should monitor it for performance, availability, and security. Also, we should optimize it to reduce costs.
- Train the team: The team should be skilled on AWS services to work efficiently, be prepared for migration, and have the best practice of AWS services. So, the team should be trained in new skills.
- Focus on automation: It helps reduce errors, improve efficiency, and accelerate the migration process. It can be done by using migration tools and automating infrastructure provisioning.
Conclusion
AWS Cloud Migration can be a difficult and complex process, but with the appropriate plan and best practices, companies can move their applications to the cloud smoothly and with little downtime. Businesses may benefit from cloud computing and stimulate innovation and growth by carefully assessing their needs, selecting the appropriate Amazon services, and adhering to best practices for migration and administration.
