The 6R’s in Cloud Migrations

13. 1st R - Retain
Not moving
Continuing to operate in the current environment
Unsupported OS / application
Financial reason e.g. riding out depreciation
Business justification e.g. just recently upgraded
Retain

14. 2nd R - Retire (Get rid of)
Decommissioning
Getting rid of applications / resources no longer needed
Duplicate resources due to M&A
Existing decommissioning program
Clustered hosts for DR / HA
Retain Retire

15. 3rd R - Rehost
Lift and Shift
Fast, predictable, repeatable, and economical
Minimal changes to operate in the cloud
Packaged software applications
Applications without an active roadmap
Ad hoc applications, no access to source code / vendor

17. 4th R – Replatform
Changing the platform only
Some changes to applications may be needed
Current OS platform going out of support
Current DB engine not fit for purpose
Changing hardware architecture

Major or Minor changes to application design & code
Leverage cloud benefits
Achieve the best optimised environment
Save costs by agility, productivity and speed
