What is AWS EBS? 

By Udit Agarwal


AWS EBS (Elastic Block Store) is a highly scalable block-level storage service offered by Amazon Web Services (AWS). It provides persistent storage volumes that can attach to Amazon EC2 instances, enabling data storage and retrieval for a wide range of applications and workloads.

EBS volumes provide consistent and low-latency performance.

They would used as primary storage for operating systems, databases, and applications or as data repositories for backups, data analytics, and other storage-intensive tasks.

Key Features and Benefits of AWS EBS:

  • Easy Management: EBS volumes can be easily created, attached, and detached from EC2 instances using the AWS Management Console, Command Line Interface (CLI), or SDKs. This flexibility allows for dynamic storage management and scaling.
  • Elasticity and Scalability: EBS volumes would dynamically resized without any downtime, allowing for easy scaling of storage capacity as per the requirements of the applications or workloads. This scalability enables efficient resource utilisation and cost optimisation.
  • Data Durability and Availability: EBS volumes automatically replicate data within an Availability Zone (AZ) to provide durability and protection against hardware failures. By utilizing EBS snapshots and AWS backup services, users can duplicate data across multiple AZs or regions to enhance data protection.
  • Snapshot Backups: EBS snapshots enable the creation of point-in-time backups of volumes, capturing the data and configuration settings at a specific moment. These snapshots can restore volumes or create new books in different regions, making replicating and recovering data accessible.
  • Performance Options: EBS offers different volume types with varying performance characteristics to cater to diverse workload requirements. These include General Purpose SSD (gp2), Provisioned IOPS SSD (io1/io2), Throughput Optimized HDD (st1), and Cold HDD (sc1). Users can choose the most appropriate volume type based on their performance needs and cost considerations.
  • Data Encryption: EBS supports encryption at rest using AWS Key Management Service (KMS). Applying encryption to new and existing volumes enables users to ensure data confidentiality and meet regulatory compliance requirements. Encryption would applied to both new and existing volumes.
  • Integration with AWS Services: EBS seamlessly integrates with various AWS services. For example, users can utilize Amazon RDS for database storage, Amazon EMR for big data processing, and Amazon EC2 Auto Scaling to automatically adjust storage capacity based on workload demands.

Use Cases for AWS EBS:

  • Database Storage: Users commonly use EBS as primary storage for databases such as MySQL, PostgreSQL, Oracle, and Microsoft SQL Server. It provides consistent and reliable performance, ensuring efficient data storage and retrieval for database-driven applications.
  • Application Hosting: EBS volumes well-suited for hosting application files, software libraries, and other static or frequently accessed content. The scalability and durability of EBS make it an ideal choice for application deployments.
  • Big Data Analytics: Many big data analytics workflows employ EBS to store large volumes of data in processing and analysis. Its high throughput and performance options enable efficient data processing for data warehousing, log processing, and machine learning tasks.
  • Disaster Recovery: EBS snapshots and data replication capabilities enable organisations to create reliable disaster recovery solutions. By replicating photos across different regions, businesses can quickly recover their systems and data in the event of a disaster.
  • DevOps and Testing Environments: EBS volumes being widely used in DevOps and testing environments to provide storage for development, testing, and staging environments. The ability to easily create and manage snapshots allows for efficient environment cloning and reproducibility.

Bottom Line

AWS Elastic Block Store (EBS) is a versatile and scalable storage service offered by AWS. It provides durable, high-performance block-level storage for various applications, databases, and workloads. With features like easy management, scalability, data durability, and integration with other AWS services. EBS is a valuable component of the AWS ecosystem, empowering organisations to build robust and scalable infrastructure in the cloud.
