HDD-backed volumes are meant for streaming workloads, where throughput is more important than IOPS. SDD-backed volumes are designed for transactional workloads where IOPS (input/output operations per second) is the most important consideration. The remainder of this post is devoted to examining them.Īll EBS volumes fall into two categories: SSD-backed volumes and HDD-backed volumes. When choosing your EBS volume types, you’ll find multiple options. EBS volumes are also very cost-effective. Each volume allows for in transit, at rest, and backup encryption. EBS provides a very secure data storage solution, since it was built with compliance in mind. If the provided performance is not enough, you can also combine multiple volumes on a single instance to achieve even better results. The block storage offered by EBS volumes can cover any workload, from the most demanding mission-critical applications requiring high throughput to large sequential jobs like data warehousing and log processing. ![]() This can later be used to recreate the data if necessary. With only a couple of clicks, you can create an EBS snapshot, effectively making a backup of your entire volume. ![]() EBS also ensures high availability (HA) and durability by replicating all data within the Availability Zone (AZ).ĮBS volumes are very easy to use, whether you need to add them to or remove them from the EC2 instance, modify their size, or change their type. This distributed way of providing storage allows for easy expansion of storage capacity when needed EBS volumes can scale into petabytes of data. It works by giving the user access to a multitude of small network-attached blocks, each of which is presented as a simple volume. What Is EBS?Īmazon Elastic Block Store (EBS) is a high-performance block storage solution designed to be used with EC2 instances. This blog post will look at the most recent volume offerings to help you by doing an EBS volume comparison to select the best one for your needs. Nevertheless, there are other options that can and should be considered. Making EBS volume choices is not as common, since most developers, by default, simply go for the standard, general purpose EBS volume types when provisioning an instance. ![]() Incorrect choices can result in a suboptimal environment which will affect the efficiency of your workloads and incur unnecessary costs.Ĭhoices are commonly made around S3 storage classes or EC2 instance types. While having options is a good thing, you need to fully understand the services available to you in order to make decisions about your business infrastructure. Working with the suite of AWS services requires making a lot of choices.
