2.1 Strategic scope
Strategy |
Scope |
Greenfield |
All services in the cloud:
- Start-up organization
- New line of business
|
Migrating existing services |
One-off migrations:
- Individual systems, services, business processes, or functionalities migrated in the cloud
- No cohesive strategy
- Each project is planned, costed, and executed independently by the team responsible
Evolutionary migrations:
- Migrating components of the operating model to the cloud over time using the guiding principle (progress iteratively with feedback)
- Which systems, services, processes, and functionalities best delivered using the cloud and which be kept in-house
- Focus on cloud compatible components or urgent migration
- Individually planned and migrated with reference to the cloud strategy
- Reviewed at closure and issues addressed in the next phase, also the strategy is reviewed regularly
- Require established business practices and regulatory risk management
- Good for organizations using large volumes of data that can be managed in parallel between the cloud and in-house environments
- Transition to new facilities to be planned smoothly and the legacy system offboarded when new processes are functioning and managed with little risk
Big-bang migrations:
- Disruption situation (for example, increased competition or mergers and acquisitions)
- New capabilities quickly realized
- Simplifies system mergers
- Focus on moving all identified components into the cloud as quickly as possible
- High risk
- Rapid re-engineering
- Use for urgent change or potentially catastrophic situation
|
New services |
Existing solutions in-house
Only new services in the cloud
In the future, may consider migrating some or all of the in-house systems to the cloud (one-off, evolutionary, or big-bang)
