Elastic Block Store (EBS) are one of the most crucial components in AWS environment. EBS volumes are block-level storage devices that can be attached to EC2 instances. But what exactly are EBS volumes, and why are they so essential?

What are Elastic Block Storage volumes?

Amazon Elastic Block Store (Amazon EBS) volumes are persistent, high-performance storage solutions designed for use with Amazon EC2 instances. They provide the raw block-level storage capacity, which means you can use them like you would any physical hard drive, but with the added benefits of scalability, reliability, and integration with AWS services.

Types of EBS

There are several types of EBS volumes, each tailored for specific needs:

• General Purpose (SSD): Suitable for a broad range of workloads, including boot volumes and low-latency interactive apps.
• Provisioned IOPS (SSD): Designed for I/O-intensive applications like large relational or NoSQL databases.
• Throughput Optimized HDD: Ideal for frequently accessed, throughput-intensive workloads.
• Cold HDD: Perfect for less frequently accessed workloads.
• Magnetic: The legacy option, best suited for workloads where data is infrequently accessed.

This is how a smart EBS Volume policy trimmed 35% of client’s AWS expenses

Elastic Block Storage Pricing

EBS pricing varies based on the type of volume you choose and the region in which your instances are running. It’s essential to understand the cost structure, which includes provisioned storage, I/O requests, and snapshot storage. AWS offers a detailed pricing page to help users estimate their EBS-related expenses in EBS pricing page official website.

If you want to see a real case where we optimized EC2 & EBS AWS cost with a lambda function, click here.

EBS Performance

Performance for EBS volumes is measured in IOPS (Input/Output Operations Per Second) and throughput. Factors like volume type, size, and the EC2 instance with which it’s associated can influence performance. AWS provides tools like EBS-optimized instances and Provisioned IOPS to help users maximize their EBS performance.

To deeply understand EBS performance on SSD, you must see how gp2 & gp3 storage works.

EBS Snapshots and Backups

EBS volumes can be backed up by taking point-in-time Amazon EBS snapshots. These snapshots are stored in Amazon S3 and can be used to instantiate new volumes or protect data for long-term archival.

EBS Security

Security is paramount in AWS, and EBS volumes are no exception. EBS volumes support encryption at rest and in transit. When you create an encrypted EBS volume, its data, snapshots, and any volumes created from those snapshots are encrypted.

Disaster Recovery

EBS volumes play a vital role in disaster recovery strategies. With features like multi-AZ deployments, snapshots, and fast replication, EBS ensures that your data remains safe and accessible even in the face of unforeseen events.

Limits and Considerations

While EBS volumes offer flexibility, there are limits. For instance, there’s a limit to the number of EBS volumes you can attach to an EC2 instance. It’s crucial to be aware of these limits and plan your infrastructure accordingly.

Choosing the right storage plays a crucial role in the performance and costs of your cloud applications. Amazon Web Services (AWS) offers two highly popular Elastic Block Store (EBS) storage types: GP2 and GP3. In this article, we’ll delve into the showdown between GP2 and GP3 for storage on EC2 instances, exploring their performance, features, and costs to help you make an informed decision.

The EBS Duel: GP2 vs. GP3 in AWS

GP2: Tried and True Speed

GP2, or General Purpose 2, is a reliable choice for many cloud applications. It offers a solid balance between performance and cost, making it a popular choice for general workloads. GP2 is based on the performance credit system, meaning you get predictable and consistent performance until you exhaust your credits.

One of GP2’s key advantages is its ability to provide good performance for read and write-intensive workloads. For applications that require quick and constant access to data, GP2 can be a wise choice. However, its storage capacity is limited compared to GP3, which might be a limitation for some applications.

GP3: Power and Flexibility

GP3, AWS’s next-generation general-purpose storage, entered the market with a clear goal: to enhance performance and efficiency. Unlike GP2, GP3 doesn’t rely on the performance credit system, meaning you can enjoy consistent performance without worrying about credits running out.

What makes GP3 even more appealing is its ability to adjust performance by modifying storage capacity and performance separately. This provides greater flexibility to adapt to changing application needs. If your application experiences demand spikes, GP3 can be adjusted to meet those needs seamlessly.

The Price of AWS storage

When it comes to making informed decisions in the cloud, cost considerations can’t be overlooked. In terms of pricing, GP2 generally has a lower base price per GB compared to GP3. However, the real difference lies in how performance is billed.

GP2 charges for the amount of provisioned storage and additionally for used performance credits. This can make costs less predictable if your application requires consistent performance.

GP3, on the other hand, bills for provisioned storage capacity and performance in Input/Output Operations Per Second (IOPS) separately. This can result in greater transparency and cost control as you know exactly what you’re paying for in terms of both performance and storage.

Comparing Amazon EBS volume types gp2 and gp3

Here is a quick comparison of cost between gp2 and gp3 volumes in the us-east-1 (N. Virginia) Region (detailed pricing examples are available here):

How to migrate from gp2 to gp3

Amazon EBS Elastic Volumes allows you modifying your volume type from gp2 to gp3 without detaching volumes or restarting instances, which means that your applications will remain uninterrupted during modifications.

Be aware that managing efficiently EBS storage volumes is user’s responsibility. Check out this post to see how we managed to improve 35% of costs in AWS by correctly managing EBS volumes.

Use Cases

So, when should you choose GP2, and when should you opt for GP3? Here are some common use cases:

• GP2: If you have a budget-conscious general workload, and moderate performance is sufficient, GP2 is a solid choice.
• GP3: For applications requiring consistent performance or experiencing fluctuating demand, GP3 is a smart choice. It’s also suitable for applications needing larger storage capacity.

Conclusion

Choosing between GP2 and GP3 on AWS for storage in EC2 instances depends on your specific needs. GP2 offers balanced performance at an affordable price, while GP3 provides greater flexibility and consistent performance at a competitive cost. To make the right decision, carefully evaluate your performance requirements, storage capacity needs, and budget.

Ultimately, the choice between GP2 and GP3 is just one part of the equation. You should also consider other factors such as network capacity, scalability, and your application’s overall architecture.
