# tCloudStop Changes the status of a launched instance on Amazon EC2 (Amazon Elastic Compute Cloud). This component accesses the cloud provider to be used (Amazon EC2) and suspends, resumes or terminates given instance(s). ## tCloudStop Standard properties These properties are used to configure tCloudStop running in the Standard Job framework. The Standard tCloudStop component belongs to the Cloud family. The component in this framework is available in all Talend products. ## Basic settings | Properties | Description | | --- | --- | | Access key and Secret key | Enter or paste the access key and the secret key required by
Amazon to authenticate your requests to its web services. These
access credentials are generated from the Security Credential view
of your Amazon account page.

To enter the secret key, click the [...]
button next to the secret key field, and then in the pop-up dialog box enter the password
between double quotes and click OK to save the
settings. | | Cloud provider | Select the cloud provider to be used. | | Action | Select the action you need tCloudStop to take in order to change the status of
a given instance. This action may be:

Suspend
Resume
Terminate

Note that if you terminate an instance, this instance
will be deleted, while a suspended instance can still be
resumed. | | Predicate | Select the instance(s) of which you need to change the status. The
options are:

Running instances: status of all the running instances will be changed.
Instances in a specific group: status of the instances of a specific instance group will be changed. You need to enter the name of that group in the Group name field.
Running instances in a specific group: status of the running instances of a specific instance group will be changed. You need to enter the name of that group in the Group name field.
Instance with predefined id: status of a given instance will be changed. You need to enter the ID of that instance in the Id field. You can find this ID on your Amazon EC2.

An instance group is composed of the instances using
the same instance name you have defined in the Instance name field of tCloudStart. | | Group name | Enter the name of the group in which you want to change the
status of given instances whose security group name or key pair name is set to
jclouds#<$group\_name> in the
tCloudStart component, where
<$group\_name> identifies the group to which the
instance belongs.

This field is available only when Instances in a
specific group or Running instances
in a specific group is selected from the Predicate list. | | Id | Enter the ID of the instance of which you need to change the
status, for
instance, "${region}/${instance id}". This field appears when
you select Instance with predefined id
from the Predicate list. | ## Advanced settings | Properties | Description | | --- | --- | | tStatCatcher Statistics | Select this check box to collect the log data at the component
level. | ## Global Variables | Variables | Description | | --- | --- | | Global Variables | ERROR\_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error checkbox is
cleared, if the component has this checkbox.

A Flow variable functions during the execution of a component
while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from
it.

instances on Amazon EC2. You can use this component to suspend,
resume or terminate the instance(s) you have deployed Jobs
on.

This component often works alongside tCloudStart to change the status of the instances
launched by the latter component. |
