From On-Premises to Cloud: Enterprise System Migration Strategy

Why Cloud Migration?

The reasons for enterprises with on-premises systems to transition to the cloud are clear.

Infrastructure Cost Reduction: Eliminate physical server purchase and maintenance costs

Scalability: Automatic scaling when traffic increases

Operational Efficiency: Reduced infrastructure management burden

Business Agility: Faster launch of new services

The 6R Migration Strategy

Rehost

Migrate existing systems to the cloud as-is. The fastest approach but with limited cloud optimization.

Replatform

Replace some components with cloud-managed services. A typical example is migrating databases to RDS.

Refactor

Redesign with cloud-native architecture. The most costly and time-consuming approach but also the most effective.

Step-by-Step Approach

Step 1: Current State Analysis

Conduct a detailed analysis of current system architecture, dependencies, and data volumes.

Step 2: Migration Planning

Select the optimal strategy (6R) for each system and determine priorities.

Step 3: Pilot Migration

Start by migrating non-critical systems to build experience.

Step 4: Full Migration

Migrate core systems in phases while minimizing downtime.

Key Considerations

Security: Ensure thorough data encryption, network isolation, and access controls

Cost Management: Establish a cloud cost monitoring framework

Training: Ensure operations staff develop cloud competencies

Conclusion

Cloud migration is not simply an infrastructure move but a core journey of digital transformation. POLYGLOTSOFT supports safe cloud transitions with a systematic migration methodology.
