While cloud has become the new normal for organisations of all sizes, many IT executives and budget owners continue to struggle to articulate the business value of moving to the cloud in terms that resonate with the board and c-suite. Join this session to walk through the impact of cloud computing on the overall IT cost base. Uncover what the typical non-cost benefits are and how they can be measured and communicated. Finally, learn an overview of the tools and support to help you on the journey. Speaker: Sudith Devan, Cloud Economics Business Development Manager, AWS
