Cloud Migration Solutions

Comprehensive guide for migrating from on-premises infrastructure to cloud platforms

The 6 Rs of Cloud Migration

Fastest
Rehost (Lift & Shift)

Move applications to the cloud without modifications

Best for:

  • Quick migration timelines
  • Legacy applications
  • Minimal business disruption
Optimized
Replatform

Make minimal cloud optimizations without changing core architecture

Best for:

  • Leveraging managed services
  • Improving performance
  • Reducing operational overhead
Modernized
Refactor/Re-architect

Reimagine application architecture using cloud-native features

Best for:

  • Achieving cloud benefits
  • Scalability requirements
  • Long-term strategic applications
Replace
Repurchase

Move to a different product, typically SaaS

Best for:

  • Replacing legacy software
  • Reducing maintenance
  • Standardizing on SaaS
Maintain
Retain

Keep applications in source environment

Best for:

  • Compliance requirements
  • Not ready for migration
  • Minimal business value
Remove
Retire

Decommission applications no longer needed

Best for:

  • Unused applications
  • Redundant systems
  • Cost reduction
