Step 1: Create an environment - AWS Migration Hub Refactor Spaces

Step 1: Create an environment

This step describes how to create an environment as part of the Refactor Spaces Getting started wizard. You can also create an environment by choosing Environments under App Refactor in the Refactor Spaces navigation pane.

A Refactor Spaces environment contains the applications, services, and the AWS infrastructure used to safely and incrementally refactor. Refactor Spaces provides a unified view across multiple AWS accounts and simplifies multi-account use cases to accelerate application refactoring. You can create an environment that orchestrates AWS Transit Gateway to bridge cross-account service communication. Alternatively, you can create an environment without a bridge and manage service-to-service communication with your own infrastructure. If you choose to use an environment's network bridge, you can achieve greater deployment independence across accounts and teams.

After an environment is created, you can share the environment with other AWS accounts, organizational units (OUs) in AWS Organizations, or an entire AWS organization. By sharing the environment with other AWS accounts, users in those accounts can create applications, services, and routes within the environment, unless you use AWS Identity and Access Management (IAM) to restrict access.

To create an environment

  1. Using the AWS account that you created in Setting up, sign in to the AWS Management Console and open the Migration Hub console at https://console.aws.amazon.com/migrationhub/.

  2. In the Migration Hub console navigation pane, choose Refactor Spaces.

  3. Choose Getting started.

  4. Select Create a refactor environment to start to incrementally modernize to microservices in multiple AWS accounts.

  5. Choose Start.

  6. Enter a name for the environment.

  7. (Optional) Add a description for the environment.

  8. (Optional) If you select the Provision Multi-account network bridge check box, Refactor Spaces creates a Transit Gateway for your microservices to communicate with your monolith directly across AWS accounts. If you want to use your own network infrastructure for communication across accounts, don't select the check box.

  9. Refactor Spaces uses a service-linked role to connect to AWS services to orchestrate them on your behalf. When you use Refactor Spaces for the first time, the service-linked role is created for you with the correct permissions. For more information about the service-linked role, see Using service-linked roles for Refactor Spaces.

  10. Choose Next to move to the Create application page.
