Using Site Factory Stacks

One of the primary strengths of Acquia Cloud Site Factory is the ability to centrally manage websites that have the same codebase and are in the same region — but what if you have some websites that are different from the rest?

If you have discrete groups of websites that share a set of basic, fundamental differences between the groups, you can use stacks to manage all of your websites in a single Acquia Cloud Site Factory subscription. Stacks use the same codebase on the same managed, dedicated infrastructure for a group of websites. Examples where this can be helpful include the following:

  • Different Drupal core - You may have some websites based on Drupal 8, while maintaining and developing a different group of websites based on Drupal 7.
  • Different installed modules - You may have websites that have fundamentally different business purposes and therefore use a different set of custom and contributed Drupal modules.
  • Different geographic region - You may have groups of websites that are based in two or more different geographic regions.

With multiple stacks in Acquia Cloud Site Factory, you can develop and maintain these groups separately, while still managing the websites in the same subscription and Site Factory Management Console. This provides you with much more flexibility, along with unified governance, assembly, and delivery.

Getting started with stacks

Each Acquia Cloud Site Factory subscription starts with a single stack — to add more stacks, contact your Acquia account manager. There is an additional cost for each stack.

Acquia will provision your additional stack and then let you know when it is ready for you to begin to develop the new stack's codebase and websites.

Your first stack will be named Stack 1, with any subsequent stacks being named Stack 2, Stack 3, and so forth. Although you cannot rename a stack, you can contact Acquia Support to request a description be added to an existing stack.

Websites managed as part of a stack share the same subdomain pattern, such as *.customer.acsitefactory.com. Each stack that is added in a different region or to a different pair of load balancers will require a unique subdomain pattern, such as *.us-east.customer.acsitefactory.com and *.eu-west.customer.acsitefactory.com.

Viewing your repository information

After provisioning is complete, you can sign in to the Acquia Cloud interface to prepare for developing websites on your new stack.

  1. Sign in to the Acquia Cloud interface as a user with platform admin permissions.
  2. Click the name of your application to select it.
  3. Click Application info to display code repository information for your stack.

Working with stacks

After adding additional stacks, you will still manage all of your Acquia Cloud Site Factory websites using the same Site Factory Management Console, regardless of which stack they are part of. When you perform many actions in the Site Factory Management Console, you will select which stack you want to work on. For example, you can perform the following actions on a per-stack basis:

Identify the stack for a website

If you have more than one Site Factory stack, you can identify what stack a website belongs to by performing the following steps:

  1. Sign in to the Site Factory Management Console as a user with the platform admin or site builder role.
  2. Click Sites.
  3. Scroll to or filter for the website with the stack that you want to identify.
  4. Point to the Information icon to display a tooltip that contains the stack information.
