Cloud Migration Cost: The Real Numbers
Cloud migration costs $50K-2M+ depending on scope, complexity, and migration strategy. A mid-market migration (50-200 applications, single cloud provider) costs $200K-600K over 12-24 weeks. Enterprise migrations (500+ applications, multi-cloud, data platform modernization included) cost $500K-2M over 6-18 months. The most commonly underestimated cost: post-migration optimization and cloud operations — budget 15-25% of migration cost annually for ongoing FinOps and operations.
Cost Breakdown by Category
| Category | % of Total | Mid-Market ($400K total) | Enterprise ($1.2M total) |
|---|---|---|---|
| Assessment & Planning | 10-15% | $40K-60K | $120K-180K |
| Migration Execution | 35-40% | $140K-160K | $420K-480K |
| Application Modernization | 20-25% | $80K-100K | $240K-300K |
| Security & Compliance | 10-15% | $40K-60K | $120K-180K |
| Testing & Validation | 10% | $40K | $120K |
| Training & Change Mgmt | 5-10% | $20K-40K | $60K-120K |
Cost by Migration Strategy
| Strategy | What It Means | Cost per App | Best For |
|---|---|---|---|
| Rehost (lift & shift) | Move VMs as-is to cloud | $2K-8K | Quick migration, minimal changes |
| Refactor | Minor code changes for cloud optimization | $10K-30K | Performance + cost improvement |
| Re-architect | Redesign for cloud-native (Kubernetes, serverless) | $30K-100K | Strategic applications |
| Replace | Swap with SaaS alternative | $5K-20K | Commodity applications |
Hidden Costs Nobody Budgets For
Egress charges: Moving data OUT of cloud costs $0.02-0.09/GB. For organizations with 100TB+ data, egress fees during testing and validation add $5K-50K. License conversion: On-premises SQL Server licenses don't automatically convert to Azure SQL — budget for Azure Hybrid Benefit assessment and potential new licensing. Network redesign: ExpressRoute or Direct Connect circuits ($1K-5K/month) for hybrid connectivity during and after migration.
How to Reduce Migration Cost
Three levers: rationalize first (decommission 20-30% of applications before migrating — most enterprises discover applications nobody uses), rehost commodity apps and re-architect strategic ones (don't over-invest in modernizing apps that just need to run in the cloud), and source specialists through Xylity (cloud architects and DevOps engineers at 20-35% below consulting rates, deployed in 4.3 days).
Key Takeaway
Cloud migration costs $200K-2M depending on scope and strategy. The biggest cost-reduction levers: rationalize applications before migrating and source specialists through Xylity at 20-35% below consulting rates. 4.3-day deployment, 92% acceptance rate.
