AWS RTB Fabric Glossary

Application

A customer-built software system that connects to RTB Fabric gateways to send or receive real-time bidding requests. Applications are external to RTB Fabric and can be requester applications that send bid requests or responder applications that receive and process bid requests. Applications connect to RTB Fabric through gateways, which handle the routing and processing of requests between applications.

Availability Zone (AZ)

Distinct locations within an AWS Region that are engineered to be isolated from failures in other AZs.

Customer

User of the service. Includes Demand-Side Platforms (DSPs) and Supply-Side Platforms (SSPs).

Demand-Side Platform (DSP)

An adtech system that allows advertisers to buy ad inventory from multiple ad exchanges through one interface. Also known as a buyer. The service helps DSPs to participate effectively in real-time bidding auctions with a high-performance, low-latency infrastructure.

Flow

Part of a link configuration that defines how RTB requests are processed. Created with the UpdateLinkModuleFlow. Flows can include RTB modules configured for specific behaviors such as additional filtering and enrichment actions. Default flows are created with links, but you can update a flow with additional modules.

Gateway

RTB Fabric infrastructure components that serve as connection points for customer applications. Requester gateways receive requests from requester applications and forward them through links to responder gateways. Responder gateways receive requests from requester gateways and forward them to responder applications, then return responses through the same pathway.

Link

The core component of RTB Fabric that establishes secure, bidirectional communication channels between gateways. Links provide authenticated communication, traffic routing and load balancing, performance monitoring, and security controls. Links can include processing logic through modules.

Requester

A customer application that sends bid requests to RTB Fabric through a requester gateway.

Resources

Gateways, links, flows, and RTB modules that comprise the RTB Fabric infrastructure. Customer applications are external to RTB Fabric and connect to these infrastructure resources.

Responder

A customer application that receives bid requests from RTB Fabric through a responder gateway and returns bid responses.

RTB module

A component that performs specific operations on RTB requests, such as filtering or enrichment. RTB modules can be configured by Supply-Side Platforms (SSPs) or Demand-Side Platforms (DSPs) in their flows, although they are not required to configure a flow. RTB Fabric provides built-in modules (QPS rate limiter, OpenRTB filter, error masker) available at no additional charge. Modules are configured using the UpdateLinkModuleFlow API operation.

Supply-Side Platform (SSP)

An adtech system that helps publishers manage and sell their ad inventory through programmatic auctions to Demand-Side Platforms (DSPs) and advertising agencies. Also known as a seller. The service helps SSPs with very low latency requirements process high volumes of real-time bid requests and responses.

Virtual private cloud (VPC)

A logically isolated network in the AWS Cloud. This virtual network resembles a traditional network that you'd operate in your own data center, with the benefits of using the scalable infrastructure of AWS. For more information, see Amazon Virtual Private Cloud (Amazon VPC).
