ACA

Components and Sizing Recommendations

Component	Options	Sizing Recommendations
AI Gateway	Deploy in your ACA environment using Terraform	Use Container Apps with at least 1 vCPU and 2 GiB of memory per replica. For high availability, deploy with auto-scaling across multiple Availability Zones.
Logs Store (optional)	Azure Blob Storage or S3-compatible storage	Each log document is ~10kb in size (uncompressed)
Cache (Prompts, Configs & Providers)	Built-in Redis or Azure Managed Redis

Prerequisites

Ensure the following tools and resources are installed and available:

Azure Subscription with permissions to create Container Apps, Key Vault, Storage, VNet, Application Gateway, etc.
Azure CLI configured with credentials
Terraform v1.5 or later

Create a Portkey Account

Go to the Portkey website.
Sign up for a Portkey account.
Once logged in, locate and save your Organisation ID for future reference. It can be found in the browser URL: https://app.portkey.ai/organisation/<organisation_id>/
Contact the Portkey AI team and provide your Organisation ID and the email address used during signup.
The Portkey team will share the following information with you:
- Docker credentials for the Gateway images (username and password).
- License: Client Auth Key.

Setup Project Environment

1. Prepare Azure Resources

# Login to Azure
az login
sub_id=<your-subscription-id>                    # Provide your azure subscription id
az account set --subscription ${sub_id}

rg=portkey-rg                                    # Provide name of resource group.
kv=portkey-kv                                    # Provide Key Vault name



# Change location as per requirement
# If Resource Group is not created yet create it with:
# az group create --name ${rg} --location eastus 

# Create a Key Vault and store your secrets

az keyvault create --name ${kv} --resource-group ${rg} --location eastus --enable-rbac-authorization true

user_id=$(az ad signed-in-user show --query id -o tsv)

az role assignment create \
  --role "Key Vault Administrator" \
  --assignee ${user_id} \
  --scope "/subscriptions/${sub_id}/resourceGroups/${rg}/providers/Microsoft.KeyVault/vaults/${kv}"

# Store Docker credentials and Portkey secrets
az keyvault secret set --vault-name ${kv} --name docker-username --value "<docker-username>"         # Docker username shared by Portkey    
az keyvault secret set --vault-name ${kv} --name docker-password --value "<docker-password>"         # Docker password shared by Portkey    
az keyvault secret set --vault-name ${kv} --name portkey-client-auth --value "<portkey-client-auth>" # Shared by Portkey 
az keyvault secret set --vault-name ${kv} --name organisations-to-sync --value "<organisation-id>"   # Provide your Portkey account organisation id

2. Create Terraform Configuration Files

Create a new directory for your deployment:

mkdir portkey-gateway
cd portkey-gateway

3. Create Module Configuration

Create a main.tf file:

terraform {
  required_version = ">= 1.5"
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "~> 4.0"
    }
  }
}

provider "azurerm" {
  features {}
}

module "portkey_gateway" {
  source = "github.com/Portkey-AI/portkey-gateway-infrastructure//terraform/aca?ref=v1.1.1"                 # Change module version as per requirement

  # Project Configuration
  project_name        = "portkey-gateway"
  environment         = "dev"
  resource_group_name = "portkey-rg"

  # Docker Registry Configuration
  registry_type       = "dockerhub"
  docker_credentials  = {
    key_vault_name  = "portkey-kv"
    key_vault_rg    = "portkey-rg"
    username_secret = "docker-username"
    password_secret = "docker-password"
  }

  # Network Configuration
  network_mode   = "none"                                                   

  # Ingress Configuration
  ingress_type          = "aca"
  public_ingress        = true

  # Storage Configuration
  # Can provide existing Azure blob storage for storing logs otherwise a storage account will be create.
  # storage_config = {
  #   resource_group = "<storage-rg>"
  #   auth_mode = "managed"
  #   account_name = "<blob-storage-account-name>"
  #   container_name = "<blob-storage-container-name>"
  # }

  # Server Mode Configuration
  server_mode    = "gateway"                                        # Set to "all" for both AI Gateway and MCP deployment


  gateway_image = {
    image = "portkeyai/gateway_enterprise"
    tag   = "2.2.2"
  }
  gateway_config = {
    cpu   = 1
    memory = "2Gi"
    min_replicas = 1
    max_replicas = 2
    port = 8787
    cpu_scale_threshold = 70
  }

  redis_config = {
    redis_type = "redis"
    cpu        = 1
    memory     = "2Gi"
  }

  environment_variables = {
    gateway = {
      LOG_LEVEL             = "info"
      NODE_ENV              = "development"
      ANALYTICS_STORE       = "control_plane"
      AZURE_MANAGED_VERSION = "2019-08-01"
    }
  }

  secrets = {
    gateway = {
      PORTKEY_CLIENT_AUTH    = "portkey-client-auth"                # Name of Key Vault secret storing the client auth value
      ORGANISATIONS_TO_SYNC  = "organisations-to-sync"              # Name of Key Vault secret storing the organisation ID
    }
  }

  # Secrets Configuration
  secrets_key_vault = {
    name           = "portkey-kv"                                   # Key Vault name where the secrets are stored
    resource_group = "portkey-rg"                                          
  }
  
  # NOTE: Values in the 'secrets' block should be the KEY VAULT SECRET NAMES, 
  # not the actual secret values. The module will retrieve the actual values 
  # from the specified Key Vault.
}
output "gateway_url" {
    value = module.portkey_gateway.gateway_url
}

Advanced Configuration

MCP Gateway (Optional)

By default, only the AI Gateway is enabled. To enable the MCP Gateway, update your terraform.tfvars: MCP Only:

server_mode = "mcp"

mcp_config = {
  cpu          = 1
  memory       = "2Gi"
  min_replicas = 2
  max_replicas = 10
  port         = 8788
}

Gateway + MCP (separate apps):

server_mode = "all"

# Gateway configuration
gateway_config = {
  cpu          = 1
  memory       = "2Gi"
  min_replicas = 2
  max_replicas = 10
  port         = 8787
}

# MCP configuration (independent scaling)
mcp_config = {
  cpu          = 0.5
  memory       = "1Gi"
  min_replicas = 1
  max_replicas = 5
  port         = 8788
}

Note: When server_mode = "all" with Application Gateway, you must configure either host-based or path-based routing.

Auto-Scaling Configuration

Control how replicas scale based on different metrics. CPU-based scaling (default):

gateway_config = {
  cpu                 = 1
  memory              = "2Gi"
  min_replicas        = 1
  max_replicas        = 10
  cpu_scale_threshold = 70  # Scale at 70% CPU
}

HTTP-based scaling:

gateway_config = {
  cpu                            = 0.5
  memory                         = "1Gi"
  min_replicas                   = 1
  max_replicas                   = 10
  cpu_scale_threshold            = null  # Disable CPU scaling
  http_scale_concurrent_requests = 100   # Scale at 100 concurrent requests per replica
}

Memory-based scaling:

gateway_config = {
  cpu                    = 1
  memory                 = "2Gi"
  min_replicas           = 2
  max_replicas           = 20
  cpu_scale_threshold    = null  # Disable CPU scaling
  memory_scale_threshold = 80    # Scale at 80% memory
}

Network Configuration with VNet

Deploy Gateway within a VNet: Create new VNet:

network_mode = "new"

vnet_config = {
  vnet_cidr                = "10.0.0.0/16"
}

Use existing VNet and subnets:

network_mode = "existing"

vnet_config = {
  vnet_id                   = "/subscriptions/<subscription-id>/resourceGroups/<rg-name>/providers/Microsoft.Network/virtualNetworks/<vnet-name>"
  aca_subnet_id             = "/subscriptions/<subscription-id>/resourceGroups/<rg-name>/providers/Microsoft.Network/virtualNetworks/<vnet-name>/subnets/<aca-subnet-name>"
  private_link_subnet_id    = "/subscriptions/<subscription-id>/resourceGroups/<rg-name>/providers/Microsoft.Network/virtualNetworks/<vnet-name>/subnets/<private-link-subnet-name>"
  app_gateway_subnet_id     = "/subscriptions/<subscription-id>/resourceGroups/<rg-name>/providers/Microsoft.Network/virtualNetworks/<vnet-name>/subnets/<app-gateway-subnet-name>"
}

Application Gateway Ingress

Deploy Azure Application Gateway with WAF, SSL termination, and zone redundancy: Basic Configuration:

network_mode = "new"  # VNet is required
ingress_type = "application_gateway"

app_gateway_config = {
  sku_name     = "Standard_v2"  # or "WAF_v2"
  sku_tier     = "Standard_v2"  # or "WAF_v2"
  capacity     = 2
  enable_waf   = false
  public       = true
  routing_mode = "host"
  gateway_host = "gateway.example.com"
}

Host-based Routing:

app_gateway_config = {
  # ... other config ...
  routing_mode = "host"
  gateway_host = "gateway.example.com"
  mcp_host     = "mcp.example.com"  # if server_mode = "all"
}

Configure DNS:

gateway.example.com  A  <app-gateway-public-ip>
mcp.example.com      A  <app-gateway-public-ip>

Path-based Routing:

app_gateway_config = {
  # ... other config ...
  routing_mode = "path"
  gateway_path = "/gateway/*"
  mcp_path     = "/mcp/*"
}

SSL Certificate:

# Import certificate to Key Vault
az keyvault certificate import \
  --vault-name my-ssl-kv \
  --name my-ssl-cert \
  --file certificate.pfx \
  --password "<pfx-password>"

app_gateway_config = {
  # ... other config ...
  ssl_cert_key_vault_secret_id = "https://my-ssl-kv.vault.azure.net/secrets/my-ssl-cert"
  ssl_cert_key_vault_rg        = "my-ssl-kv-rg"
}

Private Application Gateway:

app_gateway_config = {
  # ... other config ...
  public = false
}

Azure Managed Redis

Use Azure Cache for Redis instead of the built-in container:

redis_config = {
  redis_type = "azure-managed-redis"
  endpoint   = "rediss://<portkey-redis.redis.cache.windows.net>:6380"
  tls        = true
  mode       = "standalone"
}

Update secrets in main.tf:

secrets = {
  gateway = {
    PORTKEY_CLIENT_AUTH    = "portkey-client-auth"     # Key Vault secret name
    ORGANISATIONS_TO_SYNC  = "organisations-to-sync"   # Key Vault secret name
    REDIS_PASSWORD         = "redis-password"          # Key Vault secret name
  }
}

Note: The values above should be Key Vault secret names, not the actual secret values.

Storage Configuration

Using Auto-Created Storage (Default): No configuration needed. Terraform automatically creates a Storage Account and container. Optional: Customize container name:

storage_config = {
  container_name = "my-custom-container-name"
}

Using Existing Storage Account:

storage_config = {
  resource_group = "my-storage-account-rg"
  auth_mode      = "managed"
  account_name   = "my-storage-account-name"
  container_name = "my-container-name"
}

Integrating Gateway with Control Plane

Outbound Connectivity (Data Plane to Control Plane) Portkey supports the following methods for integrating the Data Plane with the Control Plane:

Azure Private Link
Over the Internet

Azure Private Link (Outbound)

Connect your Gateway to the Portkey Control Plane privately over Azure Private Link. Prerequisites: VNET deployment (network_mode = "new" or "existing"). Steps:

Request whitelisting — Share your Azure Subscription ID with the Portkey team. Wait for confirmation that your subscription is whitelisted.
Deploy Private Endpoint — Enable outbound Private Link in your Terraform configuration:

Add to your terraform.tfvars:

control_plane_private_link = {
  outbound = true
}

Deploy:

terraform apply

This creates:

Private Endpoint in your VNET
Private DNS Zone (privatelink-az.portkey.ai)
DNS A record (azure-cp) pointing to the Private Endpoint IP
VNET link for DNS resolution

Request connection approval — Get the Private Endpoint resource ID and share it with the Portkey team:

terraform output control_plane_private_endpoint_id

Share the output with Portkey. Wait for them to approve the connection.

Verify approval (optional):

az network private-endpoint show \
  --ids $(terraform output -raw control_plane_private_endpoint_id) \
  --query 'privateLinkServiceConnections[0].privateLinkServiceConnectionState.status' -o tsv
# Should return: "Approved"

Configure Private Endpoint URLs — Update your Gateway configuration to use the private Control Plane endpoint.

Update in main.tf:

environment_variables = {
  gateway = {
    ALBUS_BASEPATH            = "https://azure-cp.privatelink-az.portkey.ai/albus"
    CONTROL_PLANE_BASEPATH    = "https://azure-cp.privatelink-az.portkey.ai/api/v1"
    SOURCE_SYNC_API_BASEPATH  = "https://azure-cp.privatelink-az.portkey.ai/api/v1/sync"
    CONFIG_READER_PATH        = "https://azure-cp.privatelink-az.portkey.ai/api/model-configs"
  }
}

Redeploy — Apply the configuration changes:

terraform apply

Over the Internet

Ensure Gateway has access to the following endpoints over the internet:

https://api.portkey.ai
https://albus.portkey.ai

No additional configuration needed if your network allows outbound internet access.

Inbound Connectivity (Control Plane to Data Plane)

Azure Private Link
IP Whitelisting

Azure Private Link (Inbound)

Allow Portkey Control Plane to connect to your Gateway privately via Azure Private Endpoint. Prerequisites: Gateway deployed and running. Steps:

Share connection details — Get your Gateway connection information and share with the Portkey team:

# Get ACA Environment Resource ID
terraform output container_app_environment_id

# Get Gateway FQDN
terraform output inbound_gateway_fqdn

Share both outputs with Portkey:

ACA Environment Resource ID (e.g., /subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.App/managedEnvironments/xxx)
Gateway FQDN (e.g., gateway.<env-domain>.<region>.azurecontainerapps.io)

Wait for connection request — Portkey creates a Private Endpoint in their subscription targeting your ACA Environment. A connection request will appear in your Azure subscription.
Check for pending connections:

az network private-endpoint-connection list \
  --id $(terraform output -raw container_app_environment_id) \
  --type Microsoft.App/managedEnvironments \
  --query "[].{Name:name, Status:properties.privateLinkServiceConnectionState.status, Description:properties.privateLinkServiceConnectionState.description}"

Approve the connection:

az network private-endpoint-connection approve \
  --id "<connection-id-from-step-3>" \
  --description "Approved for Portkey Control Plane"

Or approve via Azure Portal: Container Apps Environment → Networking → Private endpoint connections → approve the pending request.

IP Whitelisting

Allows Control Plane to access the Data Plane over the internet by restricting inbound traffic to specific IP addresses. This method requires the Data Plane to have a publicly accessible endpoint. To whitelist, add an inbound rule to the Azure NSG or Firewall allowing connections from the Portkey Control Plane’s IPs (54.81.226.149, 34.200.113.35, 44.221.117.129) on the required port. To integrate the Control Plane with the Data Plane, contact the Portkey team and provide the Public Endpoint of the Data Plane.

Verifying Gateway Integration with the Control Plane

Send a test request to Gateway using curl.
Go to Portkey website -> Logs.
Verify that the test request appears in the logs and that you can view its full details by selecting the log entry.

Uninstalling Portkey Gateway

terraform destroy
