/**
 <fullname>Amazon Elastic Compute Cloud</fullname><p>Amazon Elastic Compute Cloud (Amazon EC2) provides secure and resizable computing capacity in the Amazon Web Services Cloud. Using Amazon EC2 eliminates the need to invest in hardware up front, so you can develop and deploy applications faster. Amazon Virtual Private Cloud (Amazon VPC) enables you to provision a logically isolated section of the Amazon Web Services Cloud where you can launch Amazon Web Services resources in a virtual network that you've defined. Amazon Elastic Block Store (Amazon EBS) provides block level storage volumes for use with EC2 instances. EBS volumes are highly available and reliable storage volumes that can be attached to any running instance and used like a hard drive.</p><p>To learn more, see the following resources:</p><ul><li><p>Amazon EC2: <a href="http://aws.amazon.com/ec2">Amazon EC2 product page</a>, <a href="https://docs.aws.amazon.com/ec2/index.html">Amazon EC2 documentation</a></p></li><li><p>Amazon EBS: <a href="http://aws.amazon.com/ebs">Amazon EBS product page</a>, <a href="https://docs.aws.amazon.com/ebs/index.html">Amazon EBS documentation</a></p></li><li><p>Amazon VPC: <a href="http://aws.amazon.com/vpc">Amazon VPC product page</a>, <a href="https://docs.aws.amazon.com/vpc/index.html">Amazon VPC documentation</a></p></li><li><p>VPN: <a href="http://aws.amazon.com/vpn">VPN product page</a>, <a href="https://docs.aws.amazon.com/vpn/index.html">VPN documentation</a></p></li></ul>

If your EBS volume is attached to a current-generation EC2 instance type, you might be able to apply these changes without stopping the instance or detaching the volume from it. For more information about modifying EBS volumes, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-modify-volume.html">Amazon EBS Elastic Volumes</a> (Linux instances) or <a href="https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ebs-modify-volume.html">Amazon EBS Elastic Volumes</a> (Windows instances).</p><p>When you complete a resize operation on your volume, you need to extend the volume's file-system size to take advantage of the new storage capacity. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-expand-volume.html#recognize-expanded-volume-linux">Extend a Linux file system</a> or <a href="https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ebs-expand-volume.html#recognize-expanded-volume-windows">Extend a Windows file system</a>.</p><p> You can use CloudWatch Events to check the status of a modification to an EBS volume. For information about CloudWatch Events, see the <a href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/">Amazon CloudWatch Events User Guide</a>. You can also track the status of a modification using <a>DescribeVolumesModifications</a>. For information about tracking status changes using either method, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring-volume-modifications.html">Monitor the progress of volume modifications</a>.</p><p>With previous-generation instance types, resizing an EBS volume might require detaching and reattaching the volume or stopping and restarting the instance.</p><p>After modifying a volume, you must wait at least six hours and ensure that the volume is in the <code>in-use</code> or <code>available</code> state before you can modify the same volume. This is sometimes referred to as a cooldown period.</p>
