Business case for Cloud

Service description

High-level rapid assessment of potential value of migration to the cloud.

The purpose of the Business Value Assessment is to estimate the benefits which could be achieved by migrating existing platforms to the cloud.  More specifically, the value assessment summarises the costs, potential savings, and soft benefits in a clear and concise format to support making the case for change.  

The assessment takes as inputs high level IT budget information and generates an estimate of the value of moving systems to the cloud, based on an industry benchmark estimating model.  

The key output of this service is a financial model for a first stage (top-down) business case for cloud migration, with accompanying narrative.
