In the previous section, we looked at the available instance types. In this section, we're going to look at the options for filesystem storage for our instance. We will cover the available options, which include local instance storage and network-attached elastic block storage.
Instance storage is SSD, or hard disk storage, that is installed in the host machine. Since it is local, you can get high disk throughput and high input/output per second, known as IOPS. However, one big caveat is the ephemeral, temporary nature of instance storage. When your instance is running, it is occupying a slot in the hypervisor of a host server. So, it has access to its share of the host machine's local storage.
However, when an instance is stopped or terminated, it is removed from the hypervisor slot, and that frees the slot for another instance to occupy it. So, to make sure that no one will be able to access your data, the local storage for your instance is wiped, and...
