‫So let's summarize what we have learned in this section.
‫The first one around the EBS volumes,
‫they are network drives that are attached
‫to one EC2 instance at a time.
‫They're mapped to a specific Availability Zone
‫and we can use the EBS snapshot feature to do backups
‫or to be able to transfer the data from one EBS volume
‫across to an other Availability Zone.
‫We've seen about AMIs.
‫There are ready to use EC2 instances images, with
‫the customizations we want.
‫And if we want to automate the process of building an AMI
‫we can use the EC2 image builder service to
‫automatically build tests and distribute AMIs.
‫We've seen EC2 instance store, which is a way
‫for us to have a very high performance hardware disc
‫this time, attached to our EC2 instance.
‫But it is lost
‫in case our instances stopped or terminated.
‫If we wanted to have a network file system,
‫we would use the EFS service.
‫With EFS service,
‫we can get a NFS that we can attach
‫to hundreds of instances within the region.
‫So there is no AZ luck,
‫now it's at the region level.
‫And if you want to cost-optimize our EFS service,
‫we could use EFS-IA,
‫which allows us to move the files that are infrequently used
‫into a lower cost tier.
‫Finally, we've seen about FSx, FSx for Windows,
‫which is a way for us to get a network file system
‫for Windows servers
‫and FSx for Luster, which is
‫for us to perform high performance computing.
‫So HPC on a Linux file system.
‫So to say for this section, I hope you liked it
‫and that I will see you in the next section.
