The document discusses strategies for accelerating cloud migration. It recommends building a Cloud Center of Excellence to develop in-house skills in cloud technologies. This includes adopting an agile development approach. The document also recommends performing portfolio discovery and analysis to prioritize applications for migration. Key decisions involve determining the best migration patterns for applications based on refactoring, rehosting, replatforming etc. An iterative approach is suggested to continuously learn, improve and optimize the migration process through establishing a "migration factory".

5. Cloud Migration – which strategy is right for you?
Hybrid Cloud
1: Intermediate solution
2: Works well with legacy systems - Retain
3: Internal compliancy – indeterminate timeframes (anything in AWS)
4: Sweat the assets
