SituationIf large organizations want to save costs and become more agile, then modernizing their application portfolio and becoming cloud-native is a must.The first step in this process is to find the right cloud transformation strategy and to have a clear business case for that transformation. This leads to some key questions:
Which cloud providers fit best?
Should we go for a lift-and-shift approach, or would a replatforming approach be better?
What is the business case for each approach?
How long would it take?
ChallengeThe main challenge in these cases is the complexity of the IT-landscape and the huge amount of services available from the cloud providers. For example, there are typically hundreds or even thousands of in-house or COTS applications, which you would need to find cloud replacements for, as well as assessing the costs for both the migration and the operation in the cloud. Additionally, each provider has complex and difficult pricing schemes, which are hard to accurately compare. These factors make it incredibly difficult to make good decisions about cloud business cases, cloud risks and the optimal providers. In the end, this typically leads to prolonged discussions within your organization about the value of the cloud transformation, delaying decisions and slowing down the overall transformation.
