Thanks for the additional information regarding your questions.
There will be great growth in Ariba solutions adoption in the market. This is cloud-based software, implemented by Ariba - the consulting needs around it are more on business process definition/blueprinting and change management aspects (not technical).
Regarding training, you can find Ariba training through training.sap.com (where you will find the rest of SAP training options). Ariba training includes live virtual sessions as well as self-serve content on the SAP Learning Hub. In the next few weeks, Ariba will start its first Learning Room as well.
