- Amazon machine image (AMI)
An Amazon Machine Image (AMI) is an encrypted machine image stored in Amazon S3. It contains all the information necessary to boot instances of your software.
- ephemeral store
See instance store.
- explicit launch permission
Launch permission granted to a specific user.
- gibibyte (GiB)
a contraction of giga binary byte, a gibibyte is 2^30 bytes or 1,073,741,824 bytes. A gigabyte is 10^9 or 1,000,000,000 bytes. So yes, Amazon has bigger bytes.
Once an AMI has been launched, the resulting running system is referred to as an instance. All instances based on the same AMI start out identical and any information on them is lost when the instances are terminated or fail.
- instance store
The disk storage associated with an instance. In the event an instance fails or is terminated, all content on the instance store is deleted.
Also known as a security group, groups define firewall rules that can be shared among a group of instances that have similar security requirements. The group is specified at instance launch.
- launch permission
AMI attribute allowing users to launch an AMI
- public AMI
An AMI that all users have launch permissions for.
A collection of instances started as part of the same launch request.
- shared AMI
AMIs that developers build and make available for other AWS developers to use.
- tebibyte (TiB)
a contraction of tera binary byte, a tebibyte is 2^40 bytes or 1,099,511,627,776 bytes. A terabyte is 10^12 or 1,000,000,000,000 bytes. So yes, Amazon has bigger bytes.
