Vantaggi
Teradata technology is still great, as are some of the people, and it is an outstanding cloud-agnostic analytical database choice which can be deployed in many different ways
Svantaggi
Despite lip service to the contrary outside Cloud Provider integration, and SI collaboration if forced, there is no real commitment to partnering. Although the technology still holds it's own, other newer technology in the same space are viewed as better in the market as a whole. They have been on a multiple year cost cutting frenzy to account for the failure of a strategy to move to indirect channels. Given the failure of the strategy, revolving door at the top other than the CEO, and uncertainty of any job in the organization, I couldn't recommend working there to anyone.
