Elastic Block Store (EBS) An Amazon EBS volume is a durable, block-level storage device that you can attach to a single EC2 instance. You can think of EBS as a cloud-based virtual hard dist. You can use EBS volumes as primary storage for data that requires frequent updates, such as the system drive for an instance or storage for a database application. You can also use them for throughput-intensiv

The main difference between gp2 and gp3, however, is gp3’s decoupling of IOPS, throughput, and volume size. This flexibility – the ability to configure each piece independently – is where the savings come in. On the opposite end of the spectrum, gp2 is quite inflexible. Sizing a gp2 volume involves considering both the storage and throughput requirements simultaneously, as volume performance h

EBS vs Instance Store

Characteristics Instance Store: Ephemeral storage: Data stored in Instance Store volumes is tied to the lifecycle of the EC2 instance. If the instance is stopped, terminated, or experiences a failure, the data is lost. High I/O performance: Instance Store provides high I/O performance and low latency since the storage is directly attached to the physical host of the EC2 instance. Instance-depen
