>>>The cloud is more important than ever before. Despite initial resistance, the cloud business in Microsoft Dynamics ERP has grown exponentially. From non-existence we’ve moved to strong performance, with more than 120 active US partners and 60% CAGR on revenue over the four years since we started. "

Yes.

Without the actual quarterly revenue data we can't say if it's reasonable for MS to claim exponential growth. Ain't marketing wonderful?
