Hello and welcome to this lecture where i shall be talking about ebs which is another method of providing storage to your ec2 instances which has different benefits to that of the instance store volumes.
Aws cold storage ebs.
2014 ebs data volume encryption.
A balanced volume type.
How to encrypt an ebs volume.
0 05 per gb month of data stored based on us east n.
Aws ebs is a great solution because of its ability to create application consistent snapshots.
Ec2 instances can be launched using either elastic block store ebs or instance store volume as root volumes and additional volumes.
Cold hdd sc1 0 025 per gb month of provisioned storage.
2016 ebs throughput optimized hdd st1 and cold hdd sc1.
Unlike some other types of storage volumes it doesn t get deleted when you terminate or stop an ec2 instance.
Once attached you can create a file system on top of these volumes run a database or use them in any other way you would use block storage.
Amazon ebs snapshots to amazon s3.
Amazon ebs allows you to create storage volumes and attach them to amazon ec2 instances.
2015 ebs boot volume encryption.
2012 ebs provisioned iops and ebs optimized instances.
Ec2 instances support two types for block level storage.
2015 larger and faster ebs volumes.
Cold hdd sc1 volumes cold hdd sc1 volumes provide low cost magnetic storage that defines performance in terms of throughput rather than iops.
What needs to be understood is the scope of ebs as a service when and why to use ebs vs other forms of ec2 accessible storage the various options and limits of ebs the various means of automating ebs volume management knowing how to best utilize ebs storage in conjunction with other aws services to implement an aws infrastructure in keeping with the pillars of the well architected framework.
Efs does provide this there will be cases where customers will want to back up their data to a persistent and isolated storage location.

With a lower throughput limit than st1 sc1 is a good fit for large sequential cold data workloads.

Much like instance store volumes ebs also provides block level storage to your ec2 instances.
0 045 per gb month of provisioned storage.
Specifically in the storage arena aws provides three popular services s3 elastic block store ebs and elastic file system efs which work quite differently and offer different levels.
