The RTB4FREE platform allows customers perform programmatic buying of digital advertising on mobile, application or web sites by bidding for supply side inventor using OpenRTB protocols. The platform is completely open source. The RTB4FREE architecture consists of distributed services that perform discrete tasks which can be scaled horizontally. We call this approach a "micro-services demand side platform (DSP)", and is shown below.
A production bidding enterprise requires multiple systems running RTB4FREE, running behind a load balancer, using a campaign manager, and a data management platform. A complete DSP using RTB4FREE is done in three "layers".
The preferred method for deployment is for each component to be instanctiated as Docker containers as part of a Docker Swarm. The advanatage of this approach is:
The RTB4FREE documentation describes the software components developed by RTB4FREE - bidder, crosstalk and campaign manager. It also describe how these core components integrate with other open source projects - Kafka/Zookeeper, Elasticsearh, Logstash, Kibana.
Deployment of the platform in production using Docker is described in detail.
Since one of the major advantages of the platform is extensibility, strategies for extending the aspects of the base platform function is also discussed.
