How to Stop, Start, and Terminating Instances in EC2?

UDA
The UDA channel is for Teradata’s Unified Data Architecture including the Analytical Ecosystem and other UDA influences. This channel provides information specific to the integration and co-existence of multiple systems, in particular when a mix of Aster, Teradata, and Hadoop are present. It is also meant to support information around the UDA enabling technologies so products like Viewpoint, Data Mover, Connectors, QueryGrid, etc.

How to Stop, Start, and Terminating Instances in EC2?

• Stopping an instance:
------------------------------
When an instance is stopped, the instance performs a normal shutdown, and then transitions to a
stopped state. All of its Amazon EBS volumes remain attached, and you can start the instance again at a
later time.You are not charged for additional instance hours while the instance is in a stopped state.
A full instance hour will be charged for every transition from a stopped state to a running state, even if this happens
multiple times within a single hour. If the instance type was changed while the instance was stopped,
you will be charged the rate for the new instance type after the instance is started. All of the associated
Amazon EBS usage of your instance, including root device usage, is billed using typical Amazon EBS prices.
When an instance is in a stopped state, you can attach or detach Amazon EBS volumes. You can also
create an AMI from the instance, and you can change the kernel, RAM disk, and instance type.

• Terminating an instance:
---------------------------------
When an instance is terminated, the instance performs a normal shutdown, then the attached Amazon
EBS volumes are deleted unless the volume's deleteOnTermination attribute is set to false. The instance
itself is also deleted, and you can't start the instance again at a later time.
To prevent accidental termination, you can disable instance termination. If you do so, ensure
that the disableApiTermination attribute is set to true for the instance. To control the
behavior of an instance shutdown, such as shutdown -h in Linux or shutdown in Windows, set the
instanceInitiatedShutdownBehavior instance attribute to stop or terminate as desired. Instances with
Amazon EBS volumes for the root device default to stop, and instances with instance-store root devices
are always terminated as the result of an instance shutdown.
