Abstraction involves changing the interface of an object and exposing it in a more useful or appropriate form. This may be done by providing a layer of software, or whatever, which makes an object or collection of objects easier to manage by exposing a different object with a different interface. An example of this would be presenting the user with a tier of a service, for example of tier of web servers and their associated load balancer. The user would then manage the whole tier as a single object, including web tier attributes and load balancing policies, rather than managing each individual component.

An API function. Also called operation or call. The activity the principal has permission to perform. The action is B in the statement "A has permission to do B to C where D applies." For example, Jane sends a request to Amazon SQS with Action=ReceiveMessage.
Amazon CloudWatch: The response initiated by the change in an alarm's state: for example, from OK to ALARM. The state change may be triggered by a metric reaching the alarm threshold, or by a SetAlarmState request. Each alarm can have one or more actions assigned to each state. Actions are performed once each time the alarm changes to a state that has an action assigned, such as an Amazon Simple Notification Service notification, an Auto Scaling policy execution or an Amazon EC2 instance stop/terminate action.

The capacity of a computer or system to perform tasks commonly associated with the higher intellectual processes characteristic of humans. AI can be seen as an attempt to model aspects of human thought on computers. Although certain aspects of AI will undoubtedly make contributions to autonomic computing, autonomic computing does not have as its primary objective the emulation of human thought.
