Containerization
What Is A Container?
A container is a secure, private area inside the SSP’s cloud where a buyer’s decisioning logic and models evaluate available inventory and signals to identify impressions most likely to fit the campaign’s audience, context, and goals. Buyers can now target higher value opportunities before bidding begins — the equivalent of a cleanroom, but in the bidstream where real-time data resides.
