Description: Amazon Elastic Block Store (EBS) is a cloud storage service that provides block-level storage volumes for use with Amazon EC2 (Elastic Compute Cloud) instances. EBS allows users to create volumes that can be attached to EC2 instances, offering a persistent and scalable storage solution. EBS volumes are highly available and durable, meaning that the data stored on them is protected against hardware failures. Additionally, EBS offers features such as snapshots, which allow users to back up their volumes and restore them in case of data loss. Volumes can be of different types, such as SSD for applications requiring high performance or HDD for large-scale data storage. This flexibility allows users to optimize costs and performance according to their specific needs. EBS is essential for applications requiring persistent storage, such as databases, file systems, and enterprise applications, providing a robust and reliable solution for cloud storage.
History: Amazon Elastic Block Store was launched in 2008 as part of the Amazon Web Services (AWS) suite. Since its introduction, it has evolved to include features such as snapshots and different volume types, adapting to the changing needs of users and the growth of cloud computing.
Uses: EBS is primarily used to provide persistent storage to EC2 instances, allowing users to run applications that require fast and reliable access to data. It is commonly used for databases, file systems, and enterprise applications that need durable and scalable storage.
Examples: A practical example of EBS is its use in a MySQL database hosted on an EC2 instance, where EBS volumes store the database data and allow backups through snapshots. Another example is storing web application files on EBS volumes, which can be accessed and modified by the EC2 instances running the application.
