Common Migration Concepts
Core concepts for migrating from cloud services to self-hosted infrastructure.
The Fundamental Shift
From Cloud Services
- Data on vendor servers
- Monthly subscription costs
- Limited control over updates
- Vendor-specific APIs
To Self-Hosted
- Data on your infrastructure
- One-time setup costs
- Full control over versions
- Standard protocols
Component Mapping
| Cloud Service | Self-Hosted Alternative | Protocol |
|---|---|---|
| Cloud Storage | MinIO | S3 API |
| Email Service | Various mail servers | SMTP/IMAP |
| Identity Provider | Various auth servers | OIDC/SAML |
Migration Stages
- Assessment - What do you have?
- Planning - How will you move it?
- Testing - Does it work?
- Execution - Do the migration
- Validation - Verify everything works
Common Challenges
Data Volume
- Large datasets take time
- Bandwidth limitations
- Storage requirements
Authentication
- Passwords can't be exported
- Need password reset strategy
- Federation options
Dependencies
- Integrated services
- API changes
- Custom workflows
Tools Categories
