Integrating with an existing Transit Gateway

Suggest edit Updated on December 1, 2021

Pega Cloud services supports attaching your Pega Cloud VPC to an existing AWS Transit Gateway that you manage. Your Transit Gateway can then act as central hub to easily route traffic between your external connections and your Pega Cloud VPC.

Before you begin: While Pega Cloud services can provide access to your Pega Cloud VPC to an existing AWS Transit Gateway, Pega Cloud services does not provide the Transit Gateway as a service. You must request that Pega Cloud services provides the configuration information you need to integrate your Pega Cloud environments into your Transit Gateway. Before Pega Cloud services can complete the integration, you must:
  • Ensure that you can access your AWS Resource Access Manager (RAM) and create a resource share for Pega Cloud services use.
  • Have a management account with sharing enabled for AWS organizations in order to create the Transit Gateway resource share.

For more information about subscribing to AWS Transit Gateway, see the official AWS Transit Gateway landing page.

Pega current does not support integrating VPN attachments to an existing Transit Gateway.

Using Transit Gateway puts you in full control of connectivity to Pega Cloud from your on premise datacenter and your existing cloud applications or services and allows you to easily connect new applications with your Pega application. Integrating Pega Cloud environments with your Transit Gateway can simplify your enterprise network topology by providing the following benefits:

  • Eliminating the need for complicated peering connections, especially in larger topologies, to let multiple environments communicate with one another
  • Removing the requirement for multiple VPN connections between each of your AWS VPCs, including your Pega VPC, and on-premises environments
  • Limiting traffic between your Pega Cloud environment and other VPCs
  • Scaling your enterprise network topology to your Pega Cloud networking demands
  • Responding to spikes in network traffic more resiliently through multiple interoperable VPCs
The following illustration provides a model of how your Pega Cloud services VPC integrates with your Transit Gateway.

To implement a Transit Gateway integration, you must complete the following steps:

  1. Request a new service by selecting New request in My Support Portal, or by contacting Pega Support with a request to integrate your Transit Gateway with your Pega Cloud environments. For the latest documentation on making requests, see My Support Portal: New Design, Streamlined Features.

  2. Update your Transit Gateway service by allowing Pega Cloud services to access your Transit Gateway:

    1. In the AWS RAM console, create a resource share.

    2. From the response to the request, or the from the call with your Pega representative, note the account number Pega Cloud services shares with you.

    3. In your RAM console, in the Principals section, enter the account number that you receive from Pega Cloud services in response to your service request.

    4. Select Create resource share.

      Note: You can use the create-resource-share AWS API to enter the account number.

      For additional information on how to create a resource share through the RAM console or by using the API, see the AWS Resource Access Manager documentation.

    After you create a resource share of your Transit Gateway, Pega Cloud services creates a resource share attachment of your Pega Cloud environment.

  3. Accept the resource share referencing your Pega Cloud environment.

    1. In your RAM console, select the Shared with me, Resource shares pane.

    2. On the Pending resource share page, add your Pega Cloud environment by selecting Accept Resource Share.

    For additional information on receiving a resource share, see the AWS Resource Access Manager documentation.
Result: You integrated the Pega Cloud VPC and VPN service into your Transit Gateway, and can now utilize the Transit Gateway to connect your Pega Cloud VPC to the rest of your enterprise network topology.
