What is Cloud Migration?
Cloud migration is the process of moving:
- Applications
- Data
- Databases
- IT resources
from on-premises systems (local servers) to cloud platforms like Amazon Web Services.
Why Do Companies Migrate to Cloud?
Organizations adopt cloud migration for several reasons:
- Cost reduction (no hardware maintenance)
- Scalability (expand resources anytime)
- Better performance
- Improved security
- Faster deployment
Cloud migration helps businesses become more agile and competitive.
Types of Cloud Migration (6 Rs Strategy)
1. Rehosting (Lift and Shift)
- Move applications without changes
- Quick and simple approach
2. Replatforming
- Make small optimizations
- Improve performance
3. Refactoring
- Redesign applications for cloud
- Best long-term solution
4. Repurchasing
- Move to SaaS-based applications
5. Retiring
- Remove unused applications
6. Retaining
- Keep some systems on-premises
AWS Services for Cloud Migration
Amazon Web Services provides several tools to support migration:
1. AWS Migration Hub
- Centralized dashboard
- Tracks migration progress
2. AWS Application Migration Service
- Moves applications to AWS
- Reduces downtime
3. AWS Database Migration Service (DMS)
- Migrates databases
- Supports multiple database engines
4. AWS Snowball
Transfers large data physically
- Useful for big data migration
5. AWS Server Migration Service (SMS)
- Migrates on-prem servers to cloud
Cloud Migration Process
Step 1: Assessment
- Analyze current infrastructure
- Identify applications and dependencies
Step 2: Planning
- Choose migration strategy
- Estimate cost and resources
Step 3: Migration
- Move applications and data
- Use AWS tools and services
Step 4: Testing
- Validate application performance
- Fix issues
Step 5: Optimization
- Improve performance
- Reduce cost
- Enhance security
Real-World Example
Consider a company using local servers:
- Migrates application to EC2
- Stores files in S3
- Uses RDS for database
- Secures network using VPC
This setup improves performance, scalability, and security.
