What is Stopping in AWS? Detailed Explanation

By CloudDefense.AI Logo

Stopping in terms of AWS refers to a feature that allows users to halt the running state of their Amazon EC2 instances, thereby suspending the compute resources and stopping the associated hourly instance billing. Stopping an instance can be crucial for cost optimization and resource management. When an instance is stopped, its EBS (Elastic Block Store) volumes remain intact, ensuring that the data stored on those volumes persists. Additionally, the instance is assigned a new IP address upon restart, which is important to consider while planning your application architecture. It is worth noting that stopping an instance is different from terminating it, as termination involves permanent deletion of the instance.

To stop an EC2 instance in AWS, users can utilize the AWS Management Console, AWS Command Line Interface (CLI), or various AWS SDKs. When stopping an instance, it is essential to ensure that any critical data or ongoing compute tasks are saved or transferred before initiating the stop action. By carefully managing the start and stop states of EC2 instances, users can significantly reduce their costs by paying only for the required compute time.

Furthermore, AWS provides the capability to schedule the stopping and starting of instances using AWS Lambda or AWS CloudWatch events. This enables users to automate the process and have instances automatically stop and start at specified times, making it even more convenient for cost optimization.

In summary, the stopping feature in AWS allows users to suspend the running state of their EC2 instances, thus saving costs and efficiently managing compute resources. By leveraging the ability to schedule the start and stop actions, users can automate the process and ensure optimal utilization of their resources. Understanding the nuances of stopping an instance and its distinction from termination is vital for effectively utilizing this feature in AWS.
