Comprehensive Cloud Migration Strategies
| Strategy | Speed to Move | Up‑Front Effort | Cloud Benefits Realised | Long‑Term Cost Profile* | Risk of Disruption | Ideal Use Cases | Typical Examples |
|---|---|---|---|---|---|---|---|
| Rehost (Lift & Shift) | Fast – days → weeks | Minimal re‑engineering | Low (runs as‑is) | 🔴 Higher if not tuned | Low | Data‑centre exit; licence renewals looming | Legacy Windows VMs, internal line‑of‑business apps |
| Replatform (Lift, Tinker & Shift) | Moderate – weeks → months | Targeted tweaks (e.g., move DB to managed service) | Medium | 🟡 Moderate | Low‑medium | Need quick wins but some perf/cost pain today | Web app + RDS, Java app + container |
| Refactor (Re‑architect) | Slowest – months | Significant code & infra changes (micro‑services, serverless) | High(autoscale, pay‑per‑use) | 🟢 Lowest once optimised | Medium‑high | Competitive‑edge workloads; scalability bottlenecks | Streaming platform, ML pipelines |
| Repurchase (Drop & Shop) | Fast | Data migration & retraining only | High (SaaS features) | 🟢 Predictable subscription | Low | Commodity functions (email, CRM, ITSM) | Exchange → M365, on‑prem Jira → Jira Cloud |
| Retention (Revisit) | N/A | None | None | As‑is | N/A | Hardware‑bound apps; strict compliance; nearing EOL | Factory control systems, mainframe apps |
The approach to cloud migration varies based on organizational needs, existing infrastructure, and business objectives. Understanding the strategic options allows you to select the most appropriate path:
Rehosting (Lift and Shift)
This approach involves moving existing applications to the cloud with minimal modifications, essentially replicating your current environment in the cloud.
Best for: Legacy applications with limited modification potential, organizations prioritizing speed over optimization, or enterprises with immediate data center exit requirements.
Considerations: While quickest to implement, this approach captures fewer cloud-native benefits and may result in higher long-term operational costs if applications aren’t optimized for cloud environments.
Replatforming (Lift, Tinker and Shift)
This strategy involves making targeted optimizations to applications during migration without changing their core architecture.
Best for: Organizations seeking a balance between migration speed and cloud optimization, systems needing specific performance improvements, or applications requiring relatively minor modifications to leverage cloud benefits.
Considerations: Requires more planning and testing than rehosting but delivers better performance and cost efficiency without complete application redesign.
Refactoring (Rearchitecting)
This approach involves significantly modifying applications to fully leverage cloud-native capabilities, often transitioning to microservices architecture, containers, or serverless computing models.
Best for: Strategic applications providing competitive advantage, systems requiring significant scalability improvements, or applications where cloud-native features would deliver substantial business value.
Considerations: Highest potential for optimization but requires significant expertise, time investment, and potential business disruption during transition periods.
Repurchasing (Drop and Shop)
This strategy involves replacing existing applications with cloud-native SaaS alternatives.
Best for: Commodity applications (email, CRM, etc.), systems where custom functionality isn’t providing competitive advantage, or applications with high maintenance costs.
Considerations: Eliminates migration complexity but may require data transfer, integration work, and user retraining.
Retention (Revisit)
Not all applications should move to the cloud immediately. Some systems may need to remain on-premises due to regulatory requirements, performance considerations, or pending retirement.
Best for: Applications with strict regulatory compliance needs, systems near end-of-life, or workloads with specialized hardware requirements.
Considerations: Requires maintaining hybrid infrastructure but prevents unnecessary migration costs for inappropriate workloads.
Methodical Migration Planning Process
Successful cloud migrations follow a structured approach:
1. Comprehensive Application Portfolio Assessment
Begin with a thorough inventory and evaluation of your current application landscape:
- Document dependencies between applications and databases
- Assess technical compatibility with target cloud platforms
- Analyze performance requirements and infrastructure utilization patterns
- Identify compliance and security requirements
- Calculate current TCO (Total Cost of Ownership)
This assessment should result in a prioritized list of applications categorized by migration strategy and business impact.
2. Cloud Platform Selection
Select the appropriate cloud environment based on organizational requirements:
- Public Cloud: AWS, Microsoft Azure, Google Cloud Platform for maximum scalability and minimal infrastructure management
- Private Cloud: Dedicated cloud environments for enhanced security and compliance
- Hybrid Cloud: Combination of public and private cloud resources for optimized workload placement
- Multi-Cloud: Services from multiple providers to avoid vendor lock-in and leverage specific provider strengths
The selection process should evaluate technical compatibility, security capabilities, geographical availability, pricing models, and support services.
3. Governance and Operating Model Design
Establish clear governance structures before migration:
- Define roles and responsibilities across cloud operations
- Create cloud usage policies and cost management frameworks
- Develop security and compliance controls
- Establish monitoring and reporting procedures
- Design disaster recovery and business continuity protocols
Organizations that establish governance frameworks before migration report 35% fewer security incidents and 28% better cost control than those who address governance reactively.
4. Migration Roadmap Development
Create a detailed migration plan including:
- Prioritized application migration sequence
- Resource requirements and skill gaps
- Detailed timelines with dependencies
- Testing and validation procedures
- Risk assessment and mitigation strategies
- Success metrics and KPIs
- Rollback plans for each migration phase
Implementation Excellence: Executing the Migration
The execution phase requires careful orchestration and technical expertise:
Data Migration Considerations
Data migration often presents the greatest challenge:
- Implement appropriate data synchronization mechanisms for transition periods
