AWS EBS Volume

Amazon Elastic Block Store (EBS) volumes are block-level storage devices that can be attached to Amazon Elastic Compute Cloud (EC2) instances. They provide persistent storage for data that requires frequent updates, such as databases and file systems.

Here are some key features of EBS volumes:

  • Persistent storage: Data stored on an EBS volume persists independently of the life of an EC2 instance. This means that even if an instance is terminated, the data on the EBS volume remains.
  • Flexible: EBS volumes can be easily attached and detached from instances, and can be used as the boot volume or additional storage.
  • Scalable: EBS volumes can be increased in size, and can range from 1 GB to 16 TB.
  • Available in different volume types: EBS volumes are available in different volume types such as General Purpose SSD (gp2), Provisioned IOPS SSD (io1), Throughput Optimized HDD (st1), Cold HDD (sc1) and Magnetic (standard), each optimized for specific workloads and use cases.
  • Backed by Amazon S3: EBS snapshots, which are point-in-time copies of EBS volumes, are stored in Amazon S3 and can be used to create new volumes or restore data.
  • Encryption: EBS volumes and snapshots can be encrypted to protect data at rest and in transit.
  • Data durability: EBS volumes are designed to provide 99.999999999

AWS EBS Volume is a block-level storage device that is designed to provide persistent storage for EC2 instances. It provides features like data durability, flexible, scalability, and different volume types to choose from. The data stored on the EBS volume can be easily managed and backed up using Amazon S3.
