Running IT-as-a-Service Part 25: Understanding the cost drivers of Application-as-a-Service
Conclusion: One of IT organisations’ objectives must be to reduce the total service cost of legacy applications by migrating them to a Cloud environment. However, achievement of the desired success largely lies in limiting the scope variations of Application-as-a-Service contracts and controlling the hidden cost drivers. This requires leveraging the lessons learnt in containing outsourcing cost and establishing flexible contracts in the legacy environment. Failure to do so may extend the legacy system lifetime and leave IT organisations with no alternative but to absorb the increased cost of application management on an ongoing basis.
