NOTE

Using Amazon VPC Lattice incurs costs outside of your GraphOS Dedicated spend. Refer to the Lattice pricing page to learn more.

How GraphOS ensures subgraph security through Lattice

When you first share Lattice services with GraphOS, it scans the Lattice services to retrieve their ARNs and domain names. Then, when you add a to a cloud , GraphOS checks that the subgraph's domain matches one of the Lattice services associated with your GraphOS organization.

As a second line of defense, use AWS IAM permissions and SigV4 to only allow traffic to subgraphs in the same GraphOS organization.

Configuration overview

To allow GraphOS cloud routers to send traffic to private subgraphs in an Amazon VPC, you must:

  1. Create a Lattice target group for each hosted in your Amazon VPC.
  2. Create a Lattice service for each in GraphOS.
  3. Share your Lattice service(s) with the Apollo AWS Organization via a resource share.
  4. Link the resource share in .

This guide offers instructions for each step.

You can also use the Apollo Terraform module to provision Lattice target groups, services, and resource shares. The module completes steps 1 - 3 of this configuration guide. Once you've set it up, you can skip to step 4—linking the provisioned resource share in GraphOS Studio. Refer to the module's README for more information.

NOTE

  • You can use Amazon VPC Lattice in your organization for other uses than routing GraphOS traffic to subgraphs. A Lattice service can be associated with multiple service networks, and GraphOS associates your Lattice services with its own service network.
  • You can only use Lattice for subgraphs in the same AWS region as your . If you need to run subgraphs in different AWS regions or run your workloads in a region not yet supported by Dedicated, please get in touch.

Step 1. Create a target group

A VPC Lattice target group is a collection of targets, or compute resources, that run your application or service. In the GraphOS context, a target group maps to a subgraph. If you have multiple subgraphs, repeat these steps for each subgraph.

  1. In the AWS Console for your region of choice, go to the VPC service page:
  1. In the left navigation, scroll down and open VPC Lattice > Target groups.

  2. Click Create target group on the top right.

  3. In the Basic configuration section, set the properties that match your subgraph resources.

    Amazon VPC service page
  4. (Optional) If you use a target type with health checks, ensure you configure your health checks. Otherwise, Lattice can't send traffic to your subgraphs.

  5. Register the targets based on your chosen target type. For example, if you selected IP addresses as your target type, add each IP address.

    Amazon VPC service page
  6. Review your targets to make sure all information is correct.

  7. Click Create target group at the bottom right corner of the page.

Congratulations! You've created an Amazon VPC Lattice target group. Repeat this process for each subgraph you want to share with GraphOS.

Step 2. Create a Lattice service

In Lattice, a service represents a self-contained software module. A VPC Lattice service has a listener that uses rules, called listener rules, that you can configure to help route traffic to your targets. In this step, you create a single VPC Lattice service with listener rules for each of your target groups.

In the GraphOS context, a Lattice service maps to a graph variant. Create one service for each of your variants.

  1. In the AWS Console for your region, go to the VPC service page:
  1. In the left navigation, scroll down and open VPC Lattice > Services.

  2. Click Create service in the top right.

  3. In the Identifiers section, enter a descriptive name for the service. Optionally, enter a description and tags.

    Amazon VPC service page
  4. In the Custom domain configuration section, leave Specify a custom domain configuration unchecked.

  5. In the Service access section, select the AWS IAM authentication type and paste the following authorization policy. This policy ensures that only the Apollo AWS Organization can send traffic to your subgraphs.

    {
    "Version": "2012-10-17",
    "Statement": [
    {
    "Effect": "Allow",
    "Principal": "*",
    "Action": "vpc-lattice-svcs:Invoke",
    "Resource": "*",
    "Condition": {
    "ForAnyValue:StringLike": {
    "aws:PrincipalOrgPaths": "o-9vaxczew6u/*/ou-leyb-l9pccq2t/ou-leyb-fvqz35yo/*"
    }
    }
    }
    ]
    }
  6. (Optional) For extra security, you can audit all the traffic coming to your subgraph by enabling Access logs in the Monitoring section.

  7. Once you've configured the service, click Next on the bottom right of the page.

  8. Define routing information to the target group you created in Step 1. Set the protocol to HTTPS and the port to 443.

    NOTE

    For security reasons, Apollo requires you to use HTTPS for your listener. Using HTTPS enforces encryption in transit of the traffic between your GraphOS cloud router and your Lattice service.

    Amazon VPC service page
  9. If you have multiple target groups, add a Listener rule for each target group.

    Amazon VPC service page
  10. Click Next at the bottom right of the page once you've configured your listener.

  11. Don't select a VPC Lattice service network. Your subgraphs will integrate with a service network managed by Apollo. Instead, click the Next button at the bottom right of the page.

  12. Ensure the information you've entered is correct. Then click Create VPC Lattice service at the bottom right of the page.

Congratulations! You've now created a Lattice service with listeners for your subgraphs.

Step 3. Share Lattice service

For GraphOS to access your Lattice service, you must share it with the Apollo AWS organization. You do this through a resource share in AWS Resource Access Manager (AWS RAM). A resource share specifies the resources to share and the consumers with whom to share them.

Amazon Virtual Private Cloud
AWS RAM
resource share
Amazon VPC
Lattice service
Subgraph 1
Subgraph 2
Subgraph 3
Apollo Cloud

If you have multiple Lattice services, you can share them all through one resource share.

  1. In the AWS Console for your region of choice, go to the Resource Access Manager service page:
  1. In the left navigation, scroll down and open Shared by me > Resource shares.

  2. Click Create resource share in the top right corner.

  3. In the Resource share name section, enter a name for your resource share.

  4. In the Resources section, select the VPC Lattice Services resource type.

  5. Select all the Lattice services that contain subgraphs.

    Amazon VPC shared resources page
  6. (Optional) Set tags for your resource share.

  7. Click the Next button at the bottom right corner of the page.

  8. Verify that the Managed permissions give access to associate the Lattice services with a service network (vpc-lattice:CreateServiceNetworkServiceAssociation and vpc-lattice:GetService). Then click the Next button at the bottom right of the page.

    Amazon VPC shared resources page
  9. In the Principals section, select Allow sharing with anyone with a principal type of AWS account. Enter the following value for the account ID: 282421723282, then click the Add button.

    Amazon VPC shared resources page
  10. Confirm that 282421723282 is the only selected principal for this resource share, then click the Next button on the bottom right corner.

  11. Confirm that all the information is correct, then click Create resource share at the bottom right of the page.

Congratulations! You've now shared your Lattice service(s) with Apollo's AWS organization.

The last step is associating your resource share with a graph in GraphOS.

NOTE

  • You have 12 hours to associate your resource share. Otherwise, AWS RAM will fail to process the invitation, and you must restart this step.
  • For security purposes, we recommend you continue to the next step immediately after creating the resource share. If you see that the resource share was Accepted or Failed in the AWS console and you didn't follow step 4 of this guide, follow the steps to remove access to private subgraphs and restart this step.

At this point, you've shared your Lattice service(s) with the Apollo AWS organization. In this step, you link each service to a particular cloud router in GraphOS Studio. The cloud router can then route client requests.

  1. In the AWS Console for your region of choice, go to the Resource Access Manager service page:
  1. In the left navigation, scroll down and open Shared by me > Resource shares.

  2. Click the resource share you created in the previous step.

  3. Copy the ARN for the resource share.

The next steps differ depending on whether you're creating a new graph in GraphOS or adding this service to an existing graph.

Setup for new graphs

  1. Go to GraphOS Studio.

  2. Click the Create New Graph tab at the top right of the screen.

  3. Follow Studio's onboarding steps to create a graph with a new private subgraph.

  4. When prompted to Provide your GraphQL API endpoint, select My endpoint is not directly accessible at the bottom of the page.

  5. Choose the backend provider you want to use for your private subgraph and the region where your subgraph should be provisioned.

    NOTE

    All private subgraphs connected to a GraphOS cloud router must be in the same region.

  6. Paste the ARN of the resource share you created and copied from your AWS Console, then click Link my Resource and Next to continue.

  7. From the dropdown menu, select the Lattice service that you want to connect to your . The URL automatically appends a default path of /api/graphql, but you can change this path if you want to.

  8. Add a Service Name to describe your Lattice service. GraphOS Studio uses this name to identify your Lattice service.

  9. Paste the for this subgraph in the Schema . You can also upload a schema file by clicking the Upload Schema button.

  1. Update the ID and the name of the supergraph that you want to add this private subgraph to. An ID and name are automatically generated based on your GraphOS organization's name, but you can change both as needed.
  2. To finish, click Create GraphOS Router.

Congratulations! You've now created a GraphOS cloud router with a private subgraph.

Setup for existing graphs

  1. Go to the graph you want to connect in GraphOS Studio.
  2. From the left sidebar, open the Subgraphs tab of your graph.
  3. Click Add a Subgraph on the right of the page.
  4. In the dialog, select the Private option, then select the AWS service you want to add from the dropdown menu. The URL automatically appends a default path of /api/graphql, but you can change this path if you want to.
  5. Add a Service Name to describe your Lattice service. GraphOS Studio uses this name to identify your Lattice service.
  6. Paste the GraphQL schema for this subgraph in the Schema field. You can also upload a schema file by clicking the Upload Schema button.
  1. To finish, click Add Subgraph.

Congratulations! You've now added a private subgraph to your GraphOS cloud router.

Next steps

After you've linked your VPC Lattice services with your cloud router, you may want to set up monitoring. The Lattice management page provides information on monitoring and how to further restrict and remove access to subgraphs. See the troubleshooting guide if you're having issues with your Lattice setup.
