According to Statista, the total volume of data created, captured, and consumed globally will go beyond 180 zettabytes by 2025. In the face of this data explosion, the conventional approach of managing on-premise storage servers is slowly becoming impractical and tedious. To overcome this challenge, many companies are adopting cloud storage solutions.

AWS defines cloud storage as a cloud computing model that enables data storage on the internet, eliminating the need for buying and managing an on-premise infrastructure. This results in numerous benefits, such as cost-effectiveness, enhanced agility, streamlined data management, and more.

There are three main types of cloud storage available in the market—object, file, and block—each with its own unique set of advantages and use cases. In this blog post, we will explain the concept of “cloud-based block storage” while analyzing all its essential characteristics comprehensively to help you pick the right storage system for your workload.

So, let’s start by explaining what cloud block storage is.

What is Cloud Block Storage?

Block storage is a storage system in which the data is divided into fixed-size blocks and stored individually. Each block has a unique identifier and can be stored in different environments, allowing the user to retrieve it quickly. For enterprise applications that demand high IOPS and low latency, block storage is the ideal choice.

Traditionally, block storage is associated with on-premise storage solutions, such as physical hard drives, storage area networks (SANs), or network-attached storage (NAS) devices within an organization’s data center. However, cloud block storage is part of the cloud computing infrastructure as a service (IaaS) offering.

Compared to the on-premise model, cloud block storage offers numerous benefits such as scalability, accessibility, cost-efficiency, etc. For instance, scaling up an on-premise block storage system will involve adding physical hardware or upgrading the existing infrastructure, which will be time-consuming and expensive.

On the other hand, with cloud block storage, the cloud service provider provisions the scaling of storage capacity while users can focus on other tasks. There are numerous cloud block storage solutions available in the market. Major cloud service providers—AWS, Azure, and GCP—offer block storage solutions tailored to diverse scenarios and use cases. Let’s go over some of the most prominent and commonly used storage solutions from them.

Different Types of Cloud Block Storage

  1. Elastic Block Storage (EBS) in AWS:
  2. EBS is the most popular and high-performing block storage solution from AWS. It provides persistent, block-level storage volumes for Amazon Elastic Cloud Compute (EC2) instances. Due to its durability and scalability, EBS can be used with a wide range of workloads. EBS offers a variety of volume types, such as General Purpose SSD, Provisioned IOPS SSD, Throughput Optimized HDD, Cold HDD, and Magnetic.

  3. Azure Managed Disks:
  4. Azure Managed Disks provide durable and highly available block-level storage that can be attached to Azure virtual machines. By simplifying the process of creating and managing storage disks, they allow the user to focus on other critical tasks. Different types of Azure Managed Disks are Ultra Disks, Premium SSD, Standard SSD, and Standard HDD.

  5. Google Cloud Persistent Disk:
  6. Google Cloud Persistent Disk is a block storage solution designed to be used with Google Cloud Compute Engine instances. Coming with top-notch durability, advanced encryption, and other performance features, Persistent Disks can be used for several mission-critical use cases. Different types of Google Cloud Persistent Disk are Standard Persistent Disks (HDD), Balanced Persistent Disks (SSD), Performance Persistent Disks (SSD), Extreme Persistent Disks (SSD), and Local SSDs.

Now that we have enough information on the different types of block storage solutions offered by major cloud service providers, let’s move on to the next section—common use cases for cloud block storage.

Common Use Cases for Cloud Block Storage

However, choosing the right cloud block storage requires a more detailed assessment of factors, such as workload performance requirements, costing, data security, backup etc., all of which need to be aligned with the overall business objectives. Let’s go over each of these factors in the next section.

Key Factors to Consider When Selecting Cloud Block Storage for Your Workload

Factors to Consider When Selecting Cloud Block Storage
  1. Latency:
  2. Often measured in milliseconds, latency represents the time taken for data to travel between the storage system and the application. Reduced latency ensures a more responsive and efficient user experience, making it an important characteristic to consider while selecting a cloud-based block storage. For instance, if the workload involves real-time processing scenarios, such as databases, latency is the primary factor that users must examine.

  3. Throughput:
  4. The next factor that users must evaluate before selecting a cloud-based block storage is throughput. Measured in megabytes or gigabytes per second, it indicates the amount of data transferred between the storage system and the application. High throughput in storage systems guarantees smooth data transfer, minimizing delays and delivering optimal performance. For example, in scenarios or workloads involving content streaming or data analytics, users must opt for cloud block storage with high throughput.

  5. Durability:
  6. Durability refers to the ability of a storage system to preserve data over time. Highly durable storage makes sure that data remains intact and accessible even during system errors, hardware malfunction, and other unforeseen events. This feature is essential for maintaining data integrity, reliability, and consistency, making durability an important factor to consider while selecting a cloud block storage.

  7. Availability:
  8. Another key factor that users must consider while choosing cloud block storage for a workload is availability. Also known as “uptime”, it denotes the percentage of time a storage system remains accessible and operational.
