1. Migration Types
a. On-Premises to Cloud
Definition: This type involves migrating workloads (applications, databases, file systems, virtual machines, etc.) from an organization’s physical data center or private infrastructure to a public cloud or hybrid cloud environment.
Technical Considerations:
- Assessment: Inventory existing assets and perform a dependency analysis to understand interconnections.
- Data Migration: Use tools like AWS Snowball for large datasets, or online migration services like Azure Migrate.
- Security: Implement encryption, IAM policies, and compliance controls before migration.
- Connectivity: Establish VPN or Direct Connect for hybrid operation during transition.
- Testing: Validate workloads in staging environments before going live.
Use Cases:
- Data Center Exit: Companies shutting down expensive, aging hardware and migrating to cloud-native platforms.
- Elasticity: Need for scaling infrastructure on demand during high-traffic events.
- DevOps Enablement: Moving to CI/CD pipelines and Infrastructure-as-Code (IaC) models.
