System and method for controlling real-time bidding for online advertisements
A method and system for controlling real-time bidding for online advertisements is disclosed. According to one embodiment, a computer-implemented method comprises communicating with a bidder and an impression server and an event tracking server. The bidder receives a real-time bidding (RTB) request containing an available impression from an exchange and places a bid corresponding to the RTB request. The impression server receives impression requests from a browser and responds to the impression requests from the browser. The event tracking server receives event requests from the browser and responds to event requests from the browser. Campaign performance data is retrieved from one or more of the impression server and the event tracking server and compared to the campaign target. The bidder is notified whether to bid for online advertisement impressions based on the campaign performance data.

8. A method for real-time configuration of in-use servers in a distributed computing environment, the method comprising:
transmitting state-change messages from a controller server to each of a plurality bidding servers to instruct each bidding server to transition state;
maintaining, by each of the bidding servers, a plurality of bidding campaigns, each bidding campaign including data that defines bidding operations for the bidding server to execute;
communicably coupling, by each of the bidding servers, to at least one bidding exchange service;
communicably coupling, by each of the bidding servers, to the controller server;
receiving, by each of the bidding servers and bid-request messages from the at least one bidding exchanges services;
entering an enabled mode by each of the bidding servers, the enabled mode comprising operating on the received bid-request messages according to the data that defines bidding operations for the bidding server to execute in order to selectively transmit bid responses to the bidding exchange;
entering a disabled mode by each of the bidding servers, the enabled mode comprising refraining from transmitting bid requests to the bidding exchange service;
transitioning by each of the bidding servers between the enabled mode and the disabled mode in response to receiving state-change messages from a controller server; and
determining, by each of the bidding servers, that communication with the controller server has been interrupted and responsively transition from the enabled mode to the disabled mode comprising:
maintaining a timer set to the most recent received timer value from the control server; and
determining that the timer has expired with no state-change message received since the start of the timer; and
responsively to determining that the timer has expired with no state-change message received since the start of the timer, transitioning from the enabled mode to the disabled mode.
9. The method of claim 8 , wherein each bidding server is configured to receive the bid requests only when in the enabled mode.
10. The method of claim 8 , wherein the state-change messages have an enable-type and a disable-type message to instruct the bidding server to transition to the enabled mode and to transition to the disabled mode, respectively.
11. The method of claim 8 , the method further comprising:
receiving, by an impression server, an impression request corresponding to a bid made by a bidding server that has been accepted by the bidding exchange service;
responding, by the impression server, to the impression request;
