Cloud Migration

Cloud Migration

Cloud Migration is the process of moving data, applications, and other business elements from an on-premises infrastructure to a cloud-based environment, or between cloud environments.

Common Misconception

Myth: Migration to the cloud is too complex and risky.

Reality: Cloud migration can be smooth with proper planning.

Migration Strategies

1. Phased Migration: Incrementally move workloads in stages to minimize risk
2. Lift-and-Shift (Rehosting): Move applications without modifications
3. Replatforming: Make minimal changes to leverage cloud capabilities
4. Refactoring/Re-architecting: Redesign applications for cloud-native features
5. Hybrid Cloud: Keep some workloads on-premises while moving others to the cloud
6. Multi-Cloud: Distribute workloads across multiple cloud providers

Key Success Factors

• Comprehensive assessment and planning
• Phased approach to minimize disruption
• Professional cloud migration services
