The document outlines the concept of cloud migration, which involves transferring an organization’s IT processes, applications, and data to a cloud environment. It details various migration types, including rehost, replatform, refactor, repurchase, retire, and retain, along with their associated benefits and challenges. Best practices for cloud migration are also provided, emphasizing the importance of developing a strategy, starting small, and investing in training.

• What is cloud migration?
• Cloud migration types
• Migration best practices

3. What is
cloud
migration?
The process of transferring a portion (or all of) an
organization’s IT processes, applications and data into to a
cloud-based environment
Cloud migration types:
• On premises to cloud environment (most common)
• Cloud environment to cloud environment
• Cloud environment to on-premises

4. Benefits (&
challenges) of
migrating to
cloud
Benefits
• Costs
• Scalability
• Flexibility
• Performance
Challenges
• Developing the right strategy
• Costs
• Security
• Organizational resistance
• Vendor lock-in

5. Cloud
migration
types
Rehost (also known as “lift and shift”)
An exact copy of an application or workload is moved without
modification

6. Cloud
migration
types
Replatform (also known as “lift, tinker and shift”)
Some modification or optimization of the application or
workload occurs

7. Cloud
migration
types
Refactor (also known as “rip and replace”)
Application or workload will be completely re-architected to be
cloud ready

8. Cloud
migration
types
Repurchase (also known as “drop and shop”)
Used when an on-premises application or workload cannot be
refactored for cloud use

9. Cloud
migration
types
Retiring
Application or workload are eliminated entirely

10. Cloud
migration
types
Retaining (also known as “revisit”)
Application or workload is kept on-premises, as is

11. Cloud
migration
types
Hybrid
A combination of two or more migration strategies

12. Remember…
No “one-size-fits-all”
approach when it comes to
cloud migrations

13. Some factors that influence cloud migration approach
Age of current
technology
Budget/cost Time Scope of work Regulatory
compliance
People and
culture

14. Migration best practices
• Develop a migration strategy and plan
• Planned migration process
• Considerations for data migration
• Considerations for storage migration
• Identify migration KPIs
• Start small
• Proof of concept
• Invest in training/skilling

15. Phased migration process*
*highly recommended
Discovery of resources
Suitability of resources
for cloud deployment
Mapping of applications
and services to cloud
solutions
Migration of servers,
services and
applications to the cloud
Operational support of
cloud services
