What are hybrid cloud migration strategies?

Organizations can transition their IT infrastructure and applications from on-premises systems to a hybrid cloud environment utilizing hybrid cloud migration strategies. Using these strategies, we can join public cloud services with on-premises infrastructure or private cloud that permits organizations to use the advantages of both environments.

Some of the hybrid cloud migration strategies are given below:

• Lift-and-shift migration
• Replatforming
• Refactoring or rearchitecting
• Repurchasing or replacing
• Retaining or rearchitecting in a hybrid model

1. Lift-and-shift migration

This method entails migrating applications from on-premises servers to the cloud without modifying the application architecture significantly. It tries to swiftly transfer applications to the cloud by replicating the old environment, which can save money and increase scalability.

2. Re-platforming

Moving apps to the cloud while making minimum modifications to the underlying architecture is known as re-platforming. Certain components of this plan may need to be modified to ensure compliance with the cloud environment. Re-platforming can improve scalability and cost-efficiency while preserving application core functionality.

3. Refactoring or rearchitecting

This method entails reimagining and redesigning apps in order to properly utilize the cloud’s capabilities. It may entail decomposing monolithic programs into microservices, implementing cloud-native designs, and utilizing platform-as-a-service (PaaS) providers. Refactoring enables organizations to fully utilize the cloud’s scalability, flexibility, and sophisticated capabilities.

4. Repurchasing or replacing

This technique entails replacing on-premises applications with cloud-based software as a service (SaaS) solutions. Instead of moving software, businesses can use cloud-native apps that are already available as services. This strategy has the advantages of requiring less maintenance and providing access to updated features given by SaaS providers.

5. Retaining or rearchitecting in a hybrid model

Organizations use this technique to keep some apps on-premises or in private clouds while transferring others to the public cloud. It enables organizations to retain control over sensitive data or essential applications while reaping cloud benefits for non-sensitive workloads.

Considerations for developing a hybrid cloud migration strategy

Organizations should evaluate application dependencies, data security, and compliance needs, performance issues, cost implications, and the skills required to manage the hybrid environment when developing a hybrid cloud migration strategy.

Each technique has advantages and disadvantages, and the choice is based on the organization’s specific needs and goals.
