When I look at leveraging cloud in current IT (of course SAP as well) landscapes, I see several trends from other industries repeating:
Energy production: In the beginning of the wide adoption of energy it was quite common (or a necessity) to produce electricity for own purpose. But main adoption was reached through letting the electricity produced by central power plants.
Manufacturing: Especially when I look at the car manufacturers, they only create a minority of value trough own work. Much more they source from Tier 2 and 3 pre-configured parts – very often already prebuilt modules to “click and finish” the cars.
Very often concerns on availability of the cloud service provider exist. If I look at the examples above I ask by myself, why a car vendor can rely at the supplier and enterprises do not rely on biggest IT companies to provide IT services stable and reliable? Where’s the difference? Everybody will agree, that energy is crucial on continuing any kind of production or creation process. But not every company has a generator to produce own electricity if the power is not available. Again – where’s the difference?
What we can learn from these already well-established sourcing models and value chains: There is a solution on dependancy – treat IT as a service, standardize the process model especially in the non-critical environment and decide on sourcing like you do id with other parts of the business.
Looking forward to learn and discuss on the examples above – if cloud computing really is the continuation of sourcing and business process support and optimization – or are there some circumstances which make IT special?
