Migration Approach

Integral approach, ‘top down’think big with a vision on the ‘complete IT in the cloud’- a big ambition needs a clear driver for a the big change

Partial approach, ‘bottom up’start small with specific cloud scenario’s like- business apps with typical cloud patterns- generic apps availabe ‘as a SaaS’ mail, collaboration- Storage/DR/backup in the cloud- Dev/Test and Training environments in the cloud
