What is EBS

Amazon Elastic Block Store (EBS) is a cloud-based storage service offered by Amazon Web Services (AWS). It provides persistent block-level storage volumes for use with Amazon EC2 instances. EBS volumes are highly available and reliable storage volumes that can be attached to any running EC2 instance and exposed as a device within the instance.

EBS volumes are designed to provide persistent storage for applications that require frequent access to data. They are ideal for applications such as databases, file systems, and applications that require a high degree of availability and durability. EBS volumes are also designed to be highly scalable, allowing users to increase or decrease the size of their volumes as needed.

EBS volumes are available in a variety of sizes and performance levels, allowing users to choose the best option for their application. EBS volumes can be configured with different performance levels, such as General Purpose (SSD) or Provisioned IOPS (SSD). General Purpose (SSD) volumes are designed for a broad range of workloads, while Provisioned IOPS (SSD) volumes are designed for applications that require high levels of I/O performance.

EBS volumes are also designed to be highly secure, with encryption at rest and in transit. EBS volumes are encrypted using the AWS Key Management Service (KMS) and can be configured to use customer-managed keys. Additionally, EBS volumes can be configured to use Amazon EBS Snapshots for backup and recovery.

In summary, Amazon EBS is a cloud-based storage service that provides persistent block-level storage volumes for use with Amazon EC2 instances. EBS volumes are highly available, reliable, and secure, and can be configured with different performance levels and sizes to meet the needs of any application.
