ec2 storage Flashcards
what are network drives attached to one ec2 inst at a time?
EBS Volumes
What ec2 instance storage is mapped to AZs?
EBS volumes
what can be used for ebs snapshots for backups or transferring ebs volumes across AZ?
EBS volumes
what creates ready-to-use ec2 instances with our customizations?
AMI
What automatically builds, tests, and distributes AMIs?
EC2 Image Builder
What is a high performance hardware disk attached to our ec2 instance and lost if our instance is stopped/terminated?
EC2 Instance Store
What is a network file system that can be attacked to 100s of instances in a region?
EFS
What is a cost-optimized stroage class for infrequent accessed files for instances?
EFS-IA
what is a network file system for Windows servers?
FSx for windows
What is a nfs for high perforamnce computing linx file sys?
FSx for Lustre
What allows your instances to persist data even after termination?
Elastic Block store volume (EBS)
What can only be mounted to once instance at a time and at CCP level?
EBS volume
what are bound to a specific AZ?
EBS volume
what is like a network usb stick?
EBS volume
what controls EBS behaviour when an ec2 instance terminates?
EBS - delete on termination attribute
What is the default for delete on termination attribute for the root EBS volume/attribute is enabled?
ebs root volume gets deleted
What is the default for delete on termination attribute for other attached ebs volumes that are not the root volume?
delete on termination attribute is disabled, thus, the volume IS NOT deleted
what controls the delete on terination attribute?
aws console/cli
When would use the delete on termination attribute?
when you want to preserve the root volume when the inst is terminated
What is backup of your ebs volume at a point in time?
ebs snapshot
what is recommended but not required when making a snapshot of ebs volume?
detach the volume first
T/F You cannot copy snapshots across AZ or region
