Amazon Elastic Block Store (EBS) is an easy to use, high performance block storage service designed for use with Amazon Elastic Compute Cloud (EC2) for both throughput and transaction intensive workloads at any scale. A broad range of workloads, such as relational and non-relational databases, enterprise applications, containerized applications, big data analytics engines, file systems, and media workflows are widely deployed on Amazon EBS.
You can choose from five different volume types to balance optimal price and performance. You can achieve single digit-millisecond latency for high performance database workloads such as SAP HANA or gigabyte per second throughput for large, sequential workloads such as Hadoop. You can change volume types, tune performance, or increase volume size without disrupting your critical applications, so you have cost-effective storage when you need it.
Designed for mission-critical systems, EBS volumes are replicated within an Availability Zone (AZ) and can easily scale to petabytes of data. Also, you can use EBS Snapshots with automated lifecycle policies to back up your volumes in Amazon S3, while ensuring geographic protection of your data and business continuity.
Benefits
Performance for any workload
EBS volumes are performant for your most demanding workloads, including mission-critical applications such as SAP, Oracle, and Microsoft products. SSD-backed options include a volume designed for high performance applications and a general purpose volume that offers strong price/performance for most workloads. HDD-backed volumes are designed for large, sequential workloads such as big data analytics engines, log processing, and data warehousing. Use Fast Snapshot Restore (FSR) to instantly receive full performance when creating an EBS volume from a snapshot.
Highly available and durable
Amazon EBS architecture offers reliability for mission-critical applications. Each volume is designed to protect against failures by replicating within the Availability Zone (AZ), offering 99.999% availability and an annual failure rate (AFR) of between 0.1%-0.2%. For simple and robust backup, use EBS Snapshots with Amazon Data Lifecycle Manager (DLM) policies to automate snapshot management. As a backup provider, use EBS direct APIs for Snapshots to achieve faster backups of EBS volumes and achieve more granular recovery point objectives (RPO). You can achieve this via the ability to read EBS snapshot data without creating new EC2 instances or EBS volumes.
Cost-effective
EBS offers five different volumes at various price points and performance benchmarks, enabling you to optimize costs and invest in a precise level of storage for your application needs. Options range from highly cost-effective CNY per gigabyte volumes to high performance volumes with high IOPS and high throughput designed for mission critical workloads. Additionally, EBS offers backups using EBS Snapshots that are incremental and save on storage costs by not duplicating data.
Easy to Use
Amazon EBS volumes are easy to create, use, encrypt, and protect. Elastic Volumes capability allows you to increase storage, tune performance up and down, and change volume types without any disruption to your workloads. EBS Snapshots allow you to easily take backups of your volumes for geographic protection of your data. Data Lifecycle Manager (DLM) is an easy-to-use tool for automating snapshot management without any additional overhead or cost.
Virtually unlimited scale
Amazon EBS enables you to increase storage without any disruption to your critical workloads. Build applications that require as little as a single GB of storage, or scale up to petabytes of data — all in just a few clicks. Snapshots can be used to quickly restore new volumes across a region's Availability Zones, enabling rapid scale.
Secure
EBS is built to be secure for data compliance. Newly created EBS volumes can be encrypted by default with a single setting in your account. EBS volumes support encryption of data at-rest, data in-transit, and all volume backups. EBS encryption is supported by all volume types, includes built-in key management infrastructure, and has zero impact on performance.
Use cases
Enterprise applications
Amazon EBS provides high availability and high durability block storage to reliably run mission-critical applications such as Oracle, SAP, Microsoft Exchange, Microsoft SharePoint, and VMware applications on VMware Cloud on Amazon Web Services.
Relational databases
Amazon EBS scales with your performance needs, whether you are supporting millions of gaming customers or billions of e-commerce transactions. Databases such as SAP HANA, Oracle, Microsoft SQL Server, MySQL and PostgreSQL are widely deployed on Amazon EBS.
Business continuity
Amazon EBS allows you to minimize data loss and recovery time with the ability to regularly back up your data and log files across different geographic regions within China. Quickly restore new volumes to launch applications in new regions in China.
NoSQL databases
Amazon EBS volumes provide consistent and low-latency performance for running NoSQL databases such as Cassandra, MongoDB, and CouchDB.
Big data analytics engines
Amazon EBS offers data persistence, dynamic performance adjustments, and the ability to detach and reattach volumes, allowing you to resize clusters for big data analytics engines such as Hadoop and Spark.
File systems & media workflows
Amazon EBS lets you scale easily with additional volumes to support growing file systems, and the choice of four different volumes to optimize price and performance.
