How to choose the right AWS migration strategy for your business


Cloud computing has become an essential tool for businesses of all sizes in today's business landscape. Cloud computing platforms such as Amazon Web Services (AWS) can help businesses transform their IT infrastructure and accomplish their objectives in a number of ways because of their scalability, flexibility, and affordability.

If you're considering migrating your applications and data to the cloud, AWS is an excellent choice. However, with a wide range of migration strategies available, it's crucial to select the approach that best aligns with your specific business needs and objectives.

Understanding AWS migration strategies

Before embarking on your migration journey, it's essential to familiarize yourself with the available AWS migration strategies. These include AWS Cloud Migration, a comprehensive service designed to seamlessly transition your applications and data to the cloud. This foundational step sets the stage for a successful migration by leveraging AWS's expertise in handling diverse workloads.

7 AWS Strategies for Migrating to the Cloud (Source: Amazon)

AWS provides a comprehensive set of migration strategies, often referred to as the 7Rs, to address various migration scenarios and application types. The strategies are:

  1. Retire: Identify and remove applications that are no longer needed or provide limited value.
  2. Retain: Keep applications in their existing on-premises environment, typically for legacy systems or applications that are tightly coupled with existing infrastructure.
  3. Rehost: Lift and shift applications to the AWS cloud without making any architectural changes. This is a straightforward approach suitable for simple applications or those with tight timelines.
  4. Replatform: Migrate applications to AWS while making minor code changes to leverage cloud-native services and improve performance. This strategy is ideal for applications that need some modernization.
  5. Repurchase: Replace existing applications with cloud-native SaaS (Software as a Service) solutions offered by AWS or third parties. This approach is suitable for applications that are outdated or no longer aligned with business needs.
  6. Refactor: Rewrite applications to take full advantage of cloud-native architectures and services. This strategy is for applications that need significant modernization to achieve optimal performance and scalability.
  7. Relocate: Move applications from one cloud environment to AWS. This strategy is relevant for organizations that have already adopted cloud computing and want to consolidate their infrastructure or move to a more cost-effective or reliable cloud platform.

Assessing your application and business needs

The first step in choosing the right AWS migration strategy is to assess your application and business needs. This involves considering factors such as:

  • The age and complexity of your applications: Legacy applications may be more difficult to migrate to than newer applications.
  • Your business criticality: Applications that are critical to your business operations may require a more conservative migration approach.
  • Your regulatory and compliance requirements: Certain industries and regulations may have specific requirements for data storage and security.
  • Your budget: The cost of migration can vary depending on the complexity of your applications and the amount of data you are migrating.

Step-by-step guide to choosing the right strategy

Once you have assessed your application and business needs, you can begin to choose the right AWS migration strategy. Here is a step-by-step guide:

  • Identify your migration goals: What do you hope to achieve by migrating to AWS?
  • Define your migration scope: Which applications and data will you be migrating?
  • Assess your current IT environment: What is your current IT infrastructure like?
  • Evaluate your migration options: Consider the seven AWS migration strategies and choose the one that best meets your needs.
  • Develop a migration plan: Create a detailed plan that outlines the migration steps, timelines, and resources required.
  • Execute your migration plan: Implement your migration plan and closely monitor the process.
  • Refine and optimize: Once your migration is complete, refine and optimize your applications and infrastructure to take full advantage of AWS.


All in all, selecting the right AWS migration strategy demands a thoughtful and strategic approach. By understanding AWS migration services, assessing your unique business needs, and following a step-by-step guide, you pave the way for a successful migration that aligns with your business goals. Whether you choose rehosting, refactoring, or any other strategy, the key is to make informed decisions that drive your business forward in the cloud era.

Engaging with experienced AWS consultants throughout this process can provide valuable insights and guidance, ensuring that your migration is not just a technical transition but a strategic move that enhances your overall business performance in the cloud.
