Well, it is not IF as a SW at all, or let’s say very small part and can’t be considered as main driver. To make situation simply - let’s say there is no IFaaS. Just imagine yourself a work as establishing of new office where you need to introduce all needed IF to make it part of a big international corporation. Or implementation of routers and FW for branches or service as IP client as Lynx/Skype. Plus portion of maintenance requests to this. This is work field where the transformation is going on. In every case it is well known tasks, no discovering, but tricky for orchestration as you need to cooperate with local support/business, where guys have different priorities and different management. Somehow like this.
