This document discusses various cloud migration strategies. It suggests starting with a partial approach by moving generic applications or non-critical infrastructure to the cloud as a first step. A full assessment of applications is needed to determine what can be retired, replaced with SaaS, refactored for PaaS, or initially rehosted on IaaS. It outlines a 5 step process for cloud migration including determining public vs private cloud, integration strategies, and transition architecture. The overall goal is to leverage the cloud platform to reduce costs and improve flexibility over time.

Migration Approach
11Cloud Migration Strategies
 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
