Cloud Orchestration with OpenStack

Your development team asks that you provision twenty identical copies of a three-tier application that contains three VMs. Each application copy must reside on its own isolated network. The team also wants to deploy additional copies in the future through a self-service portal.

What will accomplish this task?

  • A Create a Heat orchestration template for the application and then launch twenty stacks using the Horizon dashboard or OpenStack CLI.
  • B Use the Contrail fabric manager to define and launch all twenty stacks using an intent-driven automation feature.
  • C Create all twenty networks and launch each instance using the Horizon instance creation wizard.
  • D Create a Heat orchestration template for the application and then launch twenty stacks using the AppFormix user interface.
Explanation

OpenStack Heat uses templates to define and deploy complete resource stacks, including compute instances and networks. Launching a separate stack for each application copy provides repeatable, isolated deployments, and Heat stack operations are available through both the Horizon dashboard and the OpenStack CLI for self-service use.
