Embarking on your Azure journey is an exciting step towards leveraging the power of the cloud. However, selecting the appropriate migration approach is crucial for a smooth and successful transition. In this blog post, we will explore different migration approaches for Azure and provide guidance on choosing the right one for your organization’s needs.
1. Lift and Shift: Rehost Migration
- Overview: The rehost migration approach, also known as “lift and shift,” involves moving existing applications to Azure without significant modifications.
- Benefits: Quick migration, minimal disruption to the existing application architecture, immediate cost savings from reduced on-premises infrastructure.
- Suitable for: Applications with low complexity, tight timelines, or where immediate cloud adoption is a priority.

2. Optimize for Azure: Replatform Migration
- Overview: The replatform migration approach focuses on optimizing applications for Azure by leveraging cloud-native services and features.
- Benefits: Improved performance, scalability, and cost optimization by taking advantage of Azure-specific capabilities.
- Suitable for: Applications that can benefit from Azure services while maintaining most of their existing architecture.

3. Modernize and Innovate: Refactor Migration
- Overview: The refactor migration approach, also known as re-architecture, involves redesigning and redeveloping applications to fully leverage Azure’s cloud-native capabilities.
- Benefits: Enhanced scalability, flexibility, and access to advanced services, enabling innovation and modernization of the application.
- Suitable for: Applications requiring significant modernization, leveraging Azure’s PaaS offerings, and embracing cloud-native architecture patterns.

4. Replace with SaaS: Repurchase Migration
- Overview: The repurchase migration approach entails replacing existing applications with software-as-a-service (SaaS) solutions available on Azure.
- Benefits: Reduced maintenance and infrastructure overhead, quick adoption of ready-made SaaS alternatives, scalability and updates handled by the SaaS provider.
- Suitable for: Applications where suitable SaaS alternatives exist and align with specific business requirements.

5. Hybrid Deployment: Hybrid Migration
- Overview: The hybrid migration approach combines on-premises and cloud-based infrastructure, allowing for a gradual transition to Azure.
- Benefits: Flexibility to migrate workloads at a pace that suits the organization’s needs, leveraging the advantages of both on-premises and cloud environments.
- Suitable for: Organizations preferring a phased migration, specific workloads with on-premises requirements, or regulatory considerations.
