AWS solutions documentation change

Service: solutions · 2026-06-10 · Documentation low

File: solutions/latest/prebid-server-deployment-on-aws/configure-the-solution.md

Summary

Added new 'CloudFormation parameters' section detailing parameters for PrebidServerStack and BidderSimulatorStack, connectivity modes (RTB Fabric/VPC peering), and ContainerImageUri usage

Security assessment

The change documents security-related parameters like 'InstallCloudFrontAndWAF' (enables DDoS protection) and network security configurations (VPC peering/RTB Fabric), but doesn't address a specific vulnerability. Security documentation is added through parameter descriptions.

+## CloudFormation parameters
+
+This section describes the CloudFormation parameters available for the PrebidServerStack and BidderSimulatorStack. These parameters are configured at deploy time via the `deploy.sh` script or directly through CloudFormation.
+
+### PrebidServerStack parameters
+
+The following table lists the CloudFormation parameters for the primary Prebid Server stack (`prebid-server-deployment-on-aws`).
+
+Parameter | Type | Default | Description  
+---|---|---|---  
+`InstallCloudFrontAndWAF` |  String |  `Yes` |  Deploy CloudFront and AWS WAF for content delivery and DDoS protection. Set to `No` to use your own CDN (requires `SSLCertificateARN`).  
+`SSLCertificateARN` |  String |  _(empty)_ |  ARN of an SSL certificate in AWS Certificate Manager. Required only when `InstallCloudFrontAndWAF` is set to `No`.  
+`ECSTaskMinCapacity` |  Number |  `2` |  Minimum number of ECS Fargate tasks for the Prebid Server service. Provides baseline redundancy.  
+`ECSTaskMaxCapacity` |  Number |  `300` |  Maximum number of ECS Fargate tasks the service can scale to under load.  
+`RequestsPerTargetThreshold` |  Number |  `5000` |  Number of requests per target that triggers ECS auto-scaling. Valid range: 100–10000.  
+`SpotInstanceWeight` |  Number |  `1` |  Relative capacity weight for Fargate Spot instances. Set to `0` to use only on-demand capacity.  
+`ContainerImageUri` |  String |  _(empty)_ |  ECR image URI for the Prebid Server container. Leave empty to build from source during deployment. See ContainerImageUri parameter.  
+`EnableLogAnalytics` |  String |  `false` |  Enable auction-level log analytics pipeline (EFS → DataSync → S3 → Glue ETL → Athena). Allowed values: `true`, `false`.  
+`EnableRtbRequesterGateway` |  String |  `false` |  Provision an RTB Fabric Requester Gateway for partner connectivity. The Fabric Link lifecycle is managed by the `simulator-fabric-link.sh` script. Allowed values: `true`, `false`.  
+`SimulatorVpcId` |  String |  _(empty)_ |  VPC ID of the BidderSimulatorStack. Required for VPC peering connectivity mode.  
+`SimulatorAlbSgId` |  String |  _(empty)_ |  ALB Security Group ID from the BidderSimulatorStack. Allows traffic from PrebidServerStack VPC over VPC peering.  
+`SimulatorRouteTableId1` |  String |  _(empty)_ |  First private subnet route table ID from the BidderSimulatorStack VPC. Used for return traffic routing over VPC peering.  
+`SimulatorRouteTableId2` |  String |  _(empty)_ |  Second private subnet route table ID from the BidderSimulatorStack VPC. Used for return traffic routing over VPC peering.  
+`SimulatorEndpoint` |  String |  _(empty)_ |  Internal ALB DNS name of the bidder simulator. Used as the ECS bidder endpoint when VPC peering is the connectivity model.  
+  
+### BidderSimulatorStack parameters
+
+The following table lists the CloudFormation parameters for the optional Bidder Simulator stack (`BiddingServerSimulator`).
+
+Parameter | Type | Default | Description  
+---|---|---|---  
+`EnableRtbFabric` |  String |  `true` |  Deploy an RTB Fabric Responder Gateway in the simulator VPC. Set to `false` for VPC peering mode. Allowed values: `true`, `false`.  
+  
+### Connectivity modes
+
+The solution supports two connectivity models between the Prebid Server and the Bidder Simulator (or partner bidders). Choose the appropriate mode based on your region and requirements.
+
+#### RTB Fabric (recommended)
+
+RTB Fabric provides a private, low-latency network for real-time bidding traffic between a Requester Gateway (in the Prebid Server VPC) and a Responder Gateway (in the bidder VPC).
+
+**When to use:** Default mode. Use when deploying in an AWS Region that supports RTB Fabric.
+
+**How it works:**
+
+  1. Set `EnableRtbRequesterGateway=true` on PrebidServerStack to provision the Requester Gateway.
+
+  2. Set `EnableRtbFabric=true` on BidderSimulatorStack to provision the Responder Gateway.
+
+  3. After both stacks are deployed, the `simulator-fabric-link.sh` script creates a Fabric Link connecting the two gateways, waits for it to become active, and updates the ECS task definition with the link URL.
+
+
+
+
+**deploy.sh usage:**
+    
+    
+    ./deploy.sh --deploy-bidding-simulator --simulator-connectivity rtb-fabric \
+      --profile <profile> --region <region>
+
+#### VPC peering (fallback)
+
+VPC peering provides direct network connectivity between the Prebid Server VPC and the Bidder Simulator VPC using standard AWS VPC peering.
+
+**When to use:** Fallback for AWS Regions where RTB Fabric is not available.
+
+**How it works:**
+
+  1. Set `EnableRtbFabric=false` on BidderSimulatorStack (no Responder Gateway).
+
+  2. The `deploy.sh` script reads VPC peering parameters (VPC ID, ALB Security Group ID, route table IDs, and ALB endpoint) from BidderSimulatorStack outputs and passes them to PrebidServerStack.
+
+  3. PrebidServerStack creates the VPC peering connection, routes, and security group rules automatically.
+
+
+
+
+**deploy.sh usage:**
+    
+    
+    ./deploy.sh --deploy-bidding-simulator --simulator-connectivity vpc-peering \
+      --profile <profile> --region <region>
+
+###### Note
+
+The VPC peering parameters (`SimulatorVpcId`, `SimulatorAlbSgId`, `SimulatorRouteTableId1`, `SimulatorRouteTableId2`, `SimulatorEndpoint`) are populated automatically by `deploy.sh` when using `--simulator-connectivity vpc-peering`. You do not need to set them manually.
+
+### ContainerImageUri parameter
+
+The `ContainerImageUri` parameter controls how the Prebid Server container image is sourced.
+
+Value | Behavior  
+---|---  
+_(empty, default)_ |  The solution builds the Prebid Server container image from source during deployment. This is the standard CDK deployment path — CodeBuild compiles the Java application, builds the Docker image, and pushes it to ECR.  
+ECR image URI (e.g., `123456789012.dkr.ecr.us-east-1.amazonaws.com/prebid-server:latest`) |  The solution uses the specified pre-built container image directly. No build step is performed. Use this when deploying via synthesized CloudFormation templates or when you have a custom Prebid Server image in ECR.  
+  
+**Common use cases for ContainerImageUri:**
+
+  * **Pre-built image from GitHub release** — The repository includes a pre-built container image at `deployment/container/prebid-server.tar.gz` (tracked via Git LFS). The `deploy.sh --container-image` flag loads this tar.gz, pushes it to ECR, and passes the resulting URI as `ContainerImageUri`.
+
+  * **Custom Prebid Server build** — If you maintain a custom fork of Prebid Server Java with additional adapters or patches, build your image separately, push to ECR, and provide the URI.
+
+  * **CloudFormation-only deployment** — When deploying the synthesized template directly (without CDK), provide a pre-existing ECR image URI since CodeBuild is not available in this path.
