What are the types of EBS?

Amazon EBS provides six volume types: Provisioned IOPS SSD (io2 and io1), General Purpose SSD (gp3 and gp2), Throughput Optimized HDD (st1) and Cold HDD (sc1). These volume types differ in performance characteristics and price, allowing you to tailor your storage performance and cost to the needs of your applications.

What is the maximum size of an EBS storage device?

16 TiBEBS currently supports a maximum volume size of 16 TiB. This means that you can create an EBS volume as large as 16 TiB, but whether the OS recognizes all of that capacity depends on its own design characteristics and on how the volume is partitioned.

How will you secure data at rest in EBS?

How can you secure data at rest on an EBS volume? Attach the volume to an instance using EC2’s SSL interface. Create an IAM policy that restricts read and write access to the volume. Write the data randomly instead of sequentially.

How does EBS work?

The Basics. EBS starts out really simple. You create a volume from 1GB to 1TB in size and then you mount it on a device (such as /dev/sdj) on an instance, format it, and off you go. Later you can detach it, let it sit for a while, and then reattach it to a different instance.

How do you use EBS?

Step 1: Head over to EC2 –> Volumes and create a new volume of your preferred size and type. Note: Make sure the EBS volume and the instance are in the same zone. Step 2: Select the created volume, right-click and select the “attach volume” option. Step 3: Select the instance from the instance text box as shown below.
