Now what

Teradata is moving away from traditional software licenses and consulting services, focusing instead on subscription-style contracts for cloud-based services. Public cloud ARR is expected to more than double again in the next fiscal year, starting with another 165% jump in the first quarter.

Investors and analysts are embracing this effective shift toward a more profitable and easily scalable business model. It's no surprise to see Teradata's shares make a big move based on this fantastic report, although the size of the jump was greater than expected.
