AWS Environments

An Amazon Web Services (AWS) environment represents the Amazon virtual private cloud (VPC) in your AWS account where engines are deployed.

Your AWS administrator must create a VPC in your AWS account and configure automatic or manual AWS credentials for Control Hub to use. You then create an AWS environment in Control Hub that represents the VPC. When you activate the environment, Control Hub connects to the VPC using the configured credentials, provisions the AWS resources needed to run engines, and deploys engine instances to those resources.

While the environment is in an active state, Control Hub periodically verifies that the Amazon VPC exists and that the credentials are valid. Control Hub does not provision engine resources in the VPC until you create and start a deployment for this environment.

Before you create an AWS environment, your AWS administrator must complete several prerequisites.

Feature Versions

When you create an AWS environment, you select the feature version to use for that environment and for all deployments created for the environment. Later feature versions typically require additional permissions in AWS or require a restart of engines belonging to the deployments.

When creating a new environment, use the latest feature version. When a new feature version is available, change your existing environments to use the new feature version as soon as possible.

When needed, you can change an existing environment to use a previous feature version. However, changing to a previous feature version disables any newer features not available in the selected feature version.

AWS environments include the following feature versions:

Feature Version Description
AWS_2023_12_15 Includes all features available in the initial feature version, as well as support for the following enhancements:
  • Amazon EC2 spot instances - You can configure an Amazon EC2 deployment to provision EC2 spot instances, in addition to on-demand instances.

    Deployments that use the initial feature version provision EC2 on-demand instances only.

  • AWS launch templates - AWS has deprecated launch configurations and recommends migrating to launch templates, as described in the Amazon EC2 documentation. As a result, deployments using this feature version use a launch template to provision AWS resources.

    Deployments that use the initial feature version use a launch configuration.

AWS_2021_06_01 Initial version.

Required Permissions

The AWS feature versions require different permissions for the IAM policy that you create in AWS to delegate limited access to Control Hub. Use the policy for the feature version that you plan to use for the AWS environment:

IAM Policy for AWS_2023_12_15

Use the following sample IAM policy for the AWS_2023_12_15 feature version:

Changing to the AWS_2023_12_15 Feature Version

To change an existing AWS environment to use the AWS_2023_12_15 feature version, you must log in to the AWS Management Console and update the IAM policy for credentials created for the IBM StreamSets AWS environment. Then, you log in to IBM StreamSets and edit the AWS environment to enable the feature version.

After saving the edited environment, Control Hub restarts all deployments belonging to the environment, causing AWS CloudFormation to replace all of the existing EC2 instances.

  1. Log in to the AWS Management Console.
  2. Locate the IAM policy for credentials created for the IBM StreamSets AWS environment.
  3. Add the permissions in bold to the following section of the existing IAM policy:
    ...
    {
        "Sid": "0",
        "Effect": "Allow",
        "Action": [
            "ec2:DescribeImages",
            "autoscaling:DescribeScalingActivities",
            "ec2:DescribeVpcs",
             "autoscaling:DescribeAutoScalingGroups",
            "ec2:DescribeRegions",
            "autoscaling:DescribeLaunchConfigurations",
            "ec2:DescribeInstanceTypes",
            "ec2:DescribeInstanceTypeOfferings",
            "ec2:DescribeSubnets",
            "ec2:DescribeKeyPairs",
            "ec2:DescribeSecurityGroups",
            "ec2:DescribeInstances",
            "autoscaling:DescribeScheduledActions”,
            "autoscaling:DescribeWarmPool",
           "ec2:CreateLaunchTemplate",
            "ec2:DeleteLaunchTemplate",
            "ec2:CreateLaunchTemplateVersion",
            "ec2:DeleteLaunchTemplateVersions",
            "ec2:DescribeLaunchTemplates",
            "ec2:DescribeLaunchTemplateVersions",
            "ec2:RunInstances"
            ],
        "Resource": "*"
    },
    ...
  4. Log in to IBM StreamSets.
  5. In the Control Hub Navigation panel, click Set Up > Environments, click the AWS environment name, and then click Edit.
  6. For the Feature Version property, select AWS_2023_12_15 and then click Save.

    Control Hub restarts all deployments belonging to the environment.

  7. Optionally, an organization administrator can update the default feature version to use for all new AWS environments.

Credential Types

You grant Control Hub access to your AWS account using a cross-account role or access keys. Control Hub uses the credentials to access and provision resources in your Amazon VPC. Use a cross-account role for production.

You can configure the credential types in the following ways:

Automatic cross-account role
When you configure an automatic cross-account role, Control Hub prompts you to log in to your AWS account and create a CloudFormation stack named StreamSets-CAR-<Control Hub environment ID>. The CloudFormation stack then automatically generates the following credential resources:
  • Cross-account role that Control Hub assumes to perform tasks in your AWS account
  • IAM policy for the cross-account role

    The IAM policy includes the required permissions for the feature version selected for the AWS environment.

  • Default instance profile for the EC2 instances provisioned by child deployments
  • IAM policy for the default instance profile
You can edit the generated IAM policies as needed. For example, you might edit the IAM policy for the default instance profile so that the EC2 instances provisioned by child deployments can access an external resource archive file stored in a private Amazon S3 bucket.

When you delete an AWS environment configured to use automatic credentials, your AWS administrator must manually delete the CloudFormation stack which will delete the corresponding credential resources created in your AWS account.

Manual cross-account role or manual access keys

When you configure a manual cross-account role or manual access keys, your AWS administrator must manually create the required credential resources, including IAM policies, instance profiles, and a cross-account role or access keys.

When you delete an AWS environment configured to use manual credentials, your AWS administrator must manually delete the corresponding credential resources created in your AWS account.

The prerequisites that your AWS administrator completes differ, depending on how you choose to configure the credentials.

Prerequisites

Your AWS administrator must complete the following prerequisites:
  1. Create an Amazon VPC for the IBM StreamSets AWS environment to use.
  2. Configure the required credentials that Control Hub uses to access and provision resources in your Amazon VPC. The prerequisites differ, depending on how you choose to configure the credentials:

Create an Amazon VPC

Create an Amazon virtual private cloud (VPC) in your AWS account.

You can use an existing VPC. However, as a best practice, create a new VPC for the exclusive use of each IBM StreamSets AWS environment.

You can use private or public subnets within the VPC network, as long as the subnets can send outbound traffic to the internet.

For instructions on creating a VPC and on allowing subnets internet access, see the Amazon VPC documentation.

Security Group

Assign a security group to the VPC that defines the required inbound and outbound rules. You can use an existing security group or create a new group.

Allow the following traffic:
  • Inbound and outbound connections required by IBM StreamSets engines, as described in Firewall Configuration Overview.
  • Outbound connections to AWS Systems Manager. Add the IP address of the ssm.<region>.amazonaws.com host as an allowed destination.

    For the list of AWS IP addresses, see the AWS documentation.

Important: If your VPC uses network access control lists (ACLs) to control inbound and outbound traffic at the subnet level, you must define the same inbound and outbound rules for the network ACLs. IBM StreamSets AWS environments do not require that you set up network ACLs.

Automatic Credential Type

When you configure automatic cross-account role credentials, Control Hub prompts you to log in to your AWS account and create a CloudFormation stack. The CloudFormation stack then automatically generates the required credential resources.

Configure a user account with access to the AWS Management Console with the IAM permissions required to create the CloudFormation stack.

Note: AWS provides multiple methods for creating users. You can configure the required permissions for a new or existing user. Configure the permissions using your security best practices.

The AWS user account requires all permissions listed in this sample IAM policy:

{
   "Version": "2012-10-17",
   "Statement": [
       {
         "Sid": "Statement2",
         "Effect": "Allow",
         "Action": [
             "cloudformation:CreateStack",
             "cloudformation:DeleteStack",
             "cloudformation:CreateChangeSet",
             "cloudformation:GetTemplateSummary",
             "cloudformation:ListStacks",
             "cloudformation:DescribeStacks",
             "cloudformation:DescribeStackEvents",
             "cloudformation:ListStackResources",
             "cloudformation:GetStackPolicy",
             "iam:CreateRole",
             "iam:PassRole",
             "iam:GetRole",
             "iam:DeleteRole",
             "iam:DeleteRolePolicy",
             "iam:PutRolePolicy",
             "iam:GetRolePolicy",
             "iam:AttachRolePolicy",
             "iam:CreateInstanceProfile",
             "iam:DeleteInstanceProfile",
             "iam:AddRoleToInstanceProfile",
             "iam:RemoveRoleFromInstanceProfile"
         ],
         "Resource": "*"
      }
   ]
}

Manual Credential Types

When you configure manual credentials, your AWS administrator must log in to your AWS account and manually create the required credential resources, including IAM policies, instance profiles, and a cross-account role or access keys.
Important: The prerequisites also require logging into IBM StreamSets to retrieve information generated for the organization. You first must invite your AWS administrator to join your organization. You can invite the administrator using the default role assignments, or you can modify the role assignments to grant the administrator the Environment Manager role only.

To configure manual credential types, complete the following prerequisites:

  1. Configure instance profiles to associate with the provisioned EC2 instances.
  2. Configure the AWS credentials that Control Hub uses to access and provision resources in your Amazon VPC.

Configure Instance Profiles for EC2 Instances

Configure instance profiles for EC2 instances in your AWS account. When Control Hub provisions EC2 instances for an Amazon EC2 deployment belonging to this environment, it associates these instance profiles with the EC2 instances.

You can configure the instance profile used by a deployment in the following ways:
Configure a default instance profile for the environment
Configure a default instance profile for the parent AWS environment. When you create an Amazon EC2 deployment for this environment, you can simply use the default instance profile configured for the environment.
Configure a unique instance profile for each deployment
Do not configure a default instance profile for the parent AWS environment. When you create an Amazon EC2 deployment for this environment, you must configure the instance profile to use for the deployment.
Configure a default instance profile and override as needed
Configure a default instance profile for the parent AWS environment. When you create an Amazon EC2 deployment for this environment, you can use the default instance profile configured for the environment, or you can override the default and configure a different instance profile for the deployment to use.

Regardless of how you configure the instance profile for the EC2 instances, you must create the IAM policy and attach it to an instance profile as an AWS environment prerequisite. When you create the IAM policy that you attach to the AWS credentials that Control Hub uses to access your AWS account, you must include the Amazon resource name (ARN) of all instance profiles in that policy. This grants Control Hub the ability to associate the instance profiles with the EC2 instances.

Complete the following steps to configure instance profiles for provisioned EC2 instances:
  1. Create an IAM policy that grants limited access to the provisioned EC2 instances.
  2. Use the IAM policy with an instance profile.
Create an IAM Policy

Create an IAM policy in AWS that grants limited access to the provisioned EC2 instances. Use the sample policy provided below. You can make compatible changes to the policy as needed.

Note: AWS provides multiple methods for creating IAM policies. These steps provide brief instructions to create a new policy using the AWS Management Console. For instructions on using other methods, such as using the AWS CLI, see the AWS IAM documentation.
  1. In the AWS Console, go to the IAM service.
  2. In the navigation pane, click Policies, and then click Create policy.
  3. In the policy editor, click the JSON tab and paste the contents of the following sample policy:
    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Sid": "0",
                "Effect": "Allow",
                "Action": "ssm:GetParameter",
                "Resource": "arn:aws:ssm:*:<ACCOUNT_ID>:parameter/StreamSets-Deployment-Token-*"
            },
            {
                "Sid": "2",
                "Effect": "Allow",
                "Action": "s3:*Object*",
                "Resource": [
                    "arn:aws:s3:::cloudformation-waitcondition-*"
                ]
             }
        ]
    }
  4. Replace the <ACCOUNT_ID> parameter in the sample policy with your 12-digit AWS account ID.
  5. When Amazon EC2 deployments managed by this environment are configured to use an external resource archive file stored in a private Amazon S3 bucket, add the following additional statement to the IAM policy:
             {
                 "Sid": "1",
                 "Effect": "Allow",
                 "Action": "s3:GetObject*",
                 "Resource": [
                      "arn:aws:s3:::*"
                 ]
             }
    Or, instead of granting read access to all Amazon S3 buckets, restrict access to a specific bucket, as follows:
    "arn:aws:s3:::<bucket_name>/*"

    For more information about configuring external resources for deployments, see External Resources.

  6. Make additional compatible changes to the policy as needed.
  7. Click Next: Tags.
  8. Click Review policy.
  9. On the Review page, enter a policy name.

    For example, to designate that this policy is for the instance profiles used by IBM StreamSets, you might enter the name StreamSets-Instance-Profile-Policy.

  10. Click Create policy.
Use the Policy with an Instance Profile

In AWS, create an instance profile to associate with the provisioned EC2 instances. You can create a single default instance profile to use for all deployments belonging to the parent environment, or you can create a unique instance profile for each deployment.

To create the instance profile, use the AWS Management Console to create a role for Amazon EC2 and attach the IAM policy that you created to this role. When you use the AWS Management Console to create a role for Amazon EC2, the console automatically creates an instance profile and gives it the same name as the role.
Note: AWS provides multiple methods for creating IAM roles. These steps provide brief instructions to create a new role using the AWS Management Console. For instructions on using other methods, such as using the AWS CLI, see the AWS IAM documentation.
  1. In the AWS Console, go to the IAM service.
  2. In the navigation pane, click Roles, and then click Create role.
  3. Select AWS service as the type of trusted entity, and then choose EC2 as the use case.
  4. Click Next: Permissions.
  5. Search for and then select the policy that you created for IBM StreamSets instance profiles.

    For example, select StreamSets-Instance-Profile-Policy.

  6. Attach any additional policies required by the StreamSets engines running on the EC2 instances.

    For example, if your pipelines process Amazon S3 data, attach an S3 policy to the role as well.

  7. Click Next: Tags.
  8. Click Next: Review.
  9. On the Review page, enter a role name.

    For example, to designate that this role is for IBM StreamSets EC2 deployments, you might enter the name StreamSets-Deployment-EC2-Instance-Profile.

  10. Click Create role.
  11. Click the name of the role to view its details, and then copy the instance profile ARN.

    Be sure to copy the instance profile ARN, and not the role ARN. You will enter this instance profile ARN when you create the AWS environment or Amazon EC2 deployment in Control Hub.

  12. To use a unique instance profile for each deployment, simply repeat these steps to create another instance profile and attach the same IAM policy to it.

Configure AWS Credentials

You can grant Control Hub access to your AWS account using a manual cross-account role or access keys. Control Hub uses the credentials to access and provision resources in your Amazon VPC. Use a cross-account role for production.

Important: Configuring AWS credentials requires logging into IBM StreamSets to retrieve information generated for the organization. If you have not yet joined the organization, ask your organization administrator to invite you.

Complete the following steps to configure manual AWS credentials for Control Hub:

  1. Create an IAM policy that delegates limited access to Control Hub. Create the same policy when using either authentication method.
  2. Use the IAM policy with a cross-account role or with access keys.
Create an IAM Policy

For either authentication method, create an IAM policy in AWS that delegates limited access to Control Hub. Use the sample policy required for the feature version you plan to use. You can make compatible changes to the policy as needed.

  1. Copy one of the following sample policies, based on the feature version that you plan to use for the AWS environment:
    Note: When creating a new environment, use the latest feature version.
  2. In the AWS Console, go to the IAM service.
  3. In the navigation pane, click Policies, and then click Create policy.
  4. In the policy editor, click the JSON tab and paste the contents of the sample IAM policy that you copied in step 1.
  5. Replace the following parameters in the sample policy:
    Parameter Replacement Value
    <ACCOUNT_ID> Your 12-digit AWS account ID.
    <INSTANCE_PROFILE_NAME> Name of the instance profile that you created for EC2 instances provisioned by StreamSets.

    For example, enter StreamSets-Deployment-EC2-Instance-Profile.

    You can make compatible changes to the policy as needed.

  6. If you created multiple instance profiles, add each instance profile to the sample policy as follows, replacing the <INSTANCE_PROFILE_NAME_n> parameters with the name of each profile that you created:
    ...
           {
                "Sid": "4",
                "Effect": "Allow",
                "Action": "iam:PassRole",
                "Resource": [
                    "arn:aws:iam::<ACCOUNT_ID>:role/<INSTANCE_PROFILE_NAME_1>",
                    "arn:aws:iam::<ACCOUNT_ID>:role/<INSTANCE_PROFILE_NAME_2>"
                 ]
            },
    ...

    For example, if you created a default instance profile for the environment and then created a second instance profile that one deployment will use to override the default profile, enter both profile names here.

  7. Click Next: Tags.
  8. Click Review policy.
  9. On the Review page, enter a policy name.

    For example, to designate that this policy is for IBM StreamSets environments, you might enter the name StreamSets-Environment-Policy.

  10. Click Create policy.
Use the Policy with a Cross-Account Role

For cross-account role authentication, create a cross-account role and attach the IAM policy that you created to this role. Control Hub assumes this role to perform tasks in your AWS account.

Note: AWS provides multiple methods for creating cross-account roles. These steps provide brief instructions to create a new role using the AWS Management Console. For instructions on using other methods, such as using the AWS CLI, see the AWS IAM documentation.
  1. To create a cross-account role, first retrieve the unique external ID generated for your Control Hub organization.
    Important: Using the generated external ID prevents the confused deputy problem and ensures that Control Hub can assume this role only when acting on behalf of your organization.
    1. Log in to IBM StreamSets.
    2. In the Control Hub Navigation panel, click Set Up > Environments and then click the Create Environment icon: .
    3. Enter a name for the environment, and then select Amazon Web Services (AWS) for the Environment Type.
    4. Click Save & Next.
    5. Select Manual Cross-Account Role for the Credential Type.
    6. Copy the External ID value.

      You can leave this page open in the browser, cancel the environment creation, or click Save & Exit to save an incomplete environment that you finish configuring after completing the prerequisites.

  2. In the AWS Console, go to the IAM service.
  3. In the navigation pane, click Roles, and then click Create role.
  4. Select Another AWS account as the type of trusted entity.

  5. In the Account ID property, enter the IBM StreamSets AWS account ID: 632637830840.
  6. Select Require external ID and paste the external ID that you retrieved from Control Hub.
  7. Click Next: Permissions.
  8. Search for and then select the policy that you created for IBM StreamSets environments.

    For example, select StreamSets-Environment-Policy.

  9. Click Next: Tags.
  10. Click Next: Review.
  11. On the Review page, enter a role name.

    For example, to designate that this role is for IBM StreamSets environments, you might enter the name StreamSets-Environment-Role.

  12. Click Create role.
  13. Click the name of the role to view its details, and then copy the role ARN.

    You will enter this ARN when you create the AWS environment in Control Hub.

Use the Policy with Access Keys

For access keys authentication, create an IAM user with programmatic access that uses access keys, and attach the IAM policy that you created to this user. Control Hub uses these access keys to perform tasks in your AWS account.

Note: AWS provides multiple methods for creating users. These steps provide brief instructions to create a new user using the AWS Management Console. You can also attach the policy to an existing user. For instructions on using other methods, such as using the AWS CLI, see the AWS IAM documentation.
  1. In the AWS Console, go to the IAM service.
  2. In the navigation pane, click Users, and then click Add user.
  3. Enter a user name.

    For example, to designate that this user is for IBM StreamSets environments, you might enter the name StreamSets-Environment-User.

  4. For Access type, select Programmatic access.
  5. Click Next: Permissions.
  6. Select Attach existing policies directly.
  7. Search for and then select the policy that you created for IBM StreamSets environments.

    For example, select StreamSets-Environment-Policy.

  8. Click Next: Tags.
  9. Click Next: Review.
  10. Click Create User.
  11. Click Download .csv to download a CSV file that contains the access key ID and secret access key.

    You will enter these access keys when you create the AWS environment in Control Hub.

Configuring an AWS Environment

Configure an AWS environment to define where to deploy IBM StreamSets engines in your AWS account.

Important: Before configuring an environment, your AWS administrator must complete the required prerequisites.

To create a new environment, click Set Up > Environments in the Navigation panel, and then click the Create Environment icon: . Or, if you saved an incomplete environment when you retrieved the information required by the prerequisites, simply edit that environment.

To edit an existing environment, click Set Up > Environments in the Navigation panel, click the environment name, and then click Edit.

Define the Environment

Define the environment essentials, including the environment name and type, and optional tags to identify similar environments.

  1. Configure the following properties:
    Define Environment Property Description
    Environment Name Name of the environment.

    Use a brief name that informs your team of the environment use case.

    Environment Type Select one of the following types:

    Once saved, you cannot change the environment type.

    Environment Tags Optional tags that identify similar environments within Control Hub. Use environment tags to easily search and filter environments.

    Enter nested tags using the following format:

    <tag1>/<tag2>/<tag3>

    Feature Version Feature version to use for the environment and all deployments created for the environment.

    Each feature version typically requires different permissions or a restart of engines belonging to the deployments.

    When creating a new environment, use the latest feature version. When a new feature version is available, change your existing environments to use the new feature version as soon as possible.

  2. Optionally, click Show Advanced Options and configure the following advanced property:
    Define Environment Advanced Property Description
    Allow Nightly Builds Allows deployments for this environment to use nightly engine builds in addition to released engine versions. Also allows Kubernetes environments to use nightly IBM StreamSets Kubernetes agent builds.

    Nightly builds are for testing features under development and should not be used in production systems.

    The version number of a nightly build includes a -SNAPSHOT suffix and the build number. For example, 5.2.0-SNAPSHOT (Build 1013).

  3. If creating the environment, click one of the following buttons:
    • Cancel - Cancels creating the environment and exits the wizard.
    • Save & Next - Saves the environment and continues.
    • Save & Exit - Saves the environment and exits the wizard, displaying the incomplete environment in the Environments view.

Configure AWS Credentials

You grant Control Hub access to your AWS account using a cross-account role or access keys. You can configure a cross-account role automatically or manually. You can configure access keys manually only. Control Hub uses the credentials to access and provision resources in your Amazon VPC. Use a cross-account role for production.

Important: Before you configure AWS credentials, your AWS administrator must complete the required prerequisites.
The steps to configure AWS credentials differ, based on the following credential types:

For more information about each credential option, see Credential Types.

Configuring Automatic Cross-Account Role

You can use the automatic cross-account role credential type to configure the credentials that Control Hub uses to access and provision resources in your AWS account.

  1. For the Credential Type property, select Automatic Cross-Account Role.
  2. Click Generate Cross-Account Role.
  3. Sign in to the AWS Management Console using the user account configured as a prerequisite by your AWS administrator.

    The Quick create stack page displays with the required values automatically populated. Do not change the values.

  4. Select the AWS CloudFormation acknowledgement, and then click Create stack.

    A CloudFormation stack is created with a name StreamSets-CAR-<Control Hub environment ID>.

    It can take a few minutes for the CloudFormation stack to generate the required resources. When finished, the stack displays a CREATE_COMPLETE status as follows:

  5. Optionally, make compatible changes to the generated IAM policy attached to the default instance profile.
    1. Click the Resources tab.
    2. Click the physical ID of the instance profile role.
    3. Click the policy name to open the policy editor.
    4. When Amazon EC2 deployments managed by this environment are configured to use an external resource archive file stored in a private Amazon S3 bucket, add the following additional statement to the IAM policy:
               {
                   "Sid": "1",
                   "Effect": "Allow",
                   "Action": "s3:GetObject*",
                   "Resource": [
                        "arn:aws:s3:::*"
                   ]
               }
      Or, instead of granting read access to all Amazon S3 buckets, restrict access to a specific bucket, as follows:
      "arn:aws:s3:::<bucket_name>/*"

      For more information about configuring external resources for deployments, see External Resources.

    5. Make additional compatible changes to the policy as needed.
    6. Click Next and then click Save changes.
    7. Return to the CloudFormation stack details.
  6. Click the Outputs tab.
