This topic discusses adding cloud-based load generators to a scenario. When you add a cloud-based load generator to a scenario, you can add either a new load generator, or a load generator that already exists in a cloud account.
Adding a new cloud-based load generator to a scenario
The process of creating a new load generator in a cloud account is known as provisioning the load generator. When you provision a new load generator, the Load Generator software that is required to create the new load generator is installed by the Controller in the cloud. To perform this installation, the Controller uses an "image" of the required load generator. To create the new load generator, you can use either the image that is contained in the default system configuration, or you can specify an alternative image that is included in a custom configuration.
Note: You can choose to provision either a single load generator or to simultaneously provision multiple load generators with the same configuration.
Adding an existing cloud-based load generator to a scenario
When you add an existing cloud-based generator to a scenario, you select the account containing existing load generator machines.The Controller then connects to the account and lists all machines associated with that account—not just the load generator machines. You determine which machines are load generators by looking at their images. You then select one or more load generator machines to include in the scenario.
Removing a load generator at the end of a scenario run
You can specify what should happen to load generators at the end of a scenario. The options are to either leave the load generator intact, or to delete the load generator from the cloud. These options apply whether the scenario run ended successfully or failed.
Removal of a load generator at the end of a scenario varies slightly depending on whether the scenario run was successful or failed:
- If the scenario was successful, the load generator is terminated as soon as the scenario ends.
- If the scenario failed, the load generator is terminated at the time specified in the Manage Cloud Accounts dialog box. For details on the cloud account settings, see Managing Cloud Accounts - Overview.
Before you can add a cloud-based load generator to a scenario, you must have access to a cloud account. For details on to make a cloud account available, see How to Manage Cloud Accounts.
Caution: If you intend to run heavy load tests on cloud-based load generators, make sure to notify the cloud vendor before running the tests.
