When ICS was launched it delivered on of the values of PaaS namely you didn’t need to worry about setting up storage, database and compute, it was all sorted out for you. Admittedly it come with a lack of elasticity when it came to resilience and scaling. In contrast Services such as SOA CS which required you to go through each of the layers, but gave you a degree of flexibility. The whilst simpler than building SOA on-premises it still represents a laborious and fiddly process that took time.
When OIC (Oracle Integration Cloud) arrived and the introduction Universal Credits we had a pricing model that made it a lot easier to be elastic in terms of approach to resourcing, but a deployment model that following SOA CS rather than ICS. To an extend, one step forward, and another back.
Fortunately we are seeing head way that means we have recovered that backward step.
