Types of Cloud Migration

Time needed: 
In today's digital era, organizations are increasingly embracing cloud computing to enhance their operational efficiency, scalability, and cost-effectiveness. Cloud migration is the process of moving applications, data, and other business elements from on-premises infrastructure to the cloud. However, not all cloud migrations are the same. Different approaches and strategies exist to accommodate varying business needs and goals. In Ankercloud, we will explore the different types of cloud migration to help you understand which approach might be suitable for your organization.

1. Lift and Shift (Rehosting):

Lift and Shift, also known as rehosting, involves moving existing applications and data to the cloud infrastructure without any significant modifications. This approach is suitable for organizations looking for a quick and straightforward migration process. It provides minimal disruption to the application architecture but doesn't leverage the full potential of cloud-native features. It can be a useful first step for organizations planning a more extensive cloud transformation in the future.

2. Replatforming:

Replatforming involves making some modifications to the applications during migration to optimize them for the cloud environment. This approach aims to take advantage of certain cloud-native features, such as scalability or managed services, while minimizing significant changes to the application architecture. Replatforming allows organizations to achieve improved performance and cost-efficiency while reducing operational complexity.

3. Refactoring (Re-architecting):

Refactoring, also known as re-architecting, involves making significant changes to the application design and architecture to take full advantage of cloud-native features and capabilities. This approach requires reimagining the application from the ground up, optimizing it for cloud environments. By leveraging Platform as a Service (PaaS) offerings, organizations can benefit from auto-scaling, high availability, and other cloud-native features. While refactoring requires more time, effort, and resources, it offers maximum flexibility, scalability, and agility in the cloud.

4. Repurchasing (Software as a Service):

Repurchasing involves replacing existing on-premises applications with Software as a Service (SaaS) solutions. In this scenario, organizations opt to migrate to cloud-based software offerings rather than running and managing applications on their own infrastructure. This approach eliminates the need for maintaining and updating software, providing organizations with immediate access to the latest features and improvements. Repurchasing offers simplicity and reduces the burden of application maintenance but may require adapting business processes to fit the chosen SaaS solution.

5. Retiring and Retaining:

During the cloud migration process, organizations may identify certain applications or data that are no longer necessary or compatible with the cloud environment. In such cases, retiring involves decommissioning or archiving these resources. On the other hand, retaining involves keeping specific applications or data on-premises due to regulatory requirements, security concerns, or complex dependencies. A careful evaluation of the organization's needs and goals is essential to determine which resources should be retired or retained.

It's important to note that these types of cloud migration are not mutually exclusive. Organizations often adopt a combination of approaches based on their specific requirements, timeline, and available resources. Choosing the right migration strategy requires careful planning and consideration of factors such as application complexity, data dependencies, security, and compliance.
