EC2 Attach EBS Volume

Amazon Web Services (AWS)’s Elastic Compute Cloud (EC2) is a commercial web service that allows users to rent virtual computers. Using AWS EC2’s cloud infrastructure, you can build powerful servers in the cloud. This service completely eliminates the need to set up and invest in hardware, enabling you to deploy your apps quickly. With AWS EC2, you can set up servers, configure networking and security, and manage storage.

Amazon Machine Image (AMI) is your virtual machine’s software configuration. It includes elements such as operating system, application server, and applications. 

An instance is nothing but a virtual machine. AWS offers a variety of instance types, which are various combinations of CPU, storage, memory, networking capacity, and so on.  

Amazon Elastic Block Store (EBS) provides block level storage volumes that you can use with your EC2 instances. You can attach an EBS volume to any running EC2 instance and can use it as primary storage for databases, file systems, or any app that requires frequent updates and quick access to the data.

If you want to attach a created EBS volume to a running or stopped EC2 instance, you can use this action. To perform this task, you first need to configure the action, and select the required AWS connection. Select the region in which the new EBS volume and your EC2 instance reside.

In the next field ‘Volume ID’, enter the ID of the EBS volume that needs to be attached. Then, in the ‘Instance ID’ filed, specify the ID of the EC2 instance to which you wish to attach the EBS volume. However, you need to ensure that the Specified EBS volume and the EC2 instance to which you want to attach the volume should be in the same Availability Zone. Also mention the device name that you want to use.

You can also perform a dry run to check if you have the required permissions to perform this action. Once you have entered all the required details, click on ‘Done’ and run the workflow. This will attach the EBS volume to the given EC2 instance.
