2. IaaS Server as a Service Storage as a Service
Connectivtiy as a Service

3. We used Amazon EC2 (Server as a Service) to create a virtual web server.
But the server instance is not persisted.
We would like to address this issue by using Amazon’s Storage as a Service in conjunction with Amazon’s Server as a Service

4. Amazon’s Storage as a Service
Amazon Simple Storage Service (Amazon S3)
Amazon Elastic Block Store (EBS)

6. Amazon Elastic Block Store (EBS): Features
EBS can provide an persistant storage to an EC2 instance
Safety & Replication: “EBS volume data is replicated across multiple servers”
Large data storage capacity: An EBS volume can be up to 1TB. You can attach multiple EBS volume to your instance (for this course, we only use a capacity allowed by the free usage tier).
Instance type portability: An EBS volume can be easily ported to another instance
Improved performance: EBS IO rates can be even faster than local disk IO
Fast and easy backups

7. Steps to use EBS
1. Create a volume with a proper size (Say 20GB for this course).
Attach this EBS volume to your EC2 instance
Format your EBS volume
Mount the volume
Move data to this volume
Create snapshots of the EBS volume
Instantiate new volume from a snapshots

8. Create EBS Volume

9. Create EBS Volume

10. Create EBS Volume

11. Attach EBS Volume

12. Attach EBS Volume

13. Format EBS Volume
#sudo mkfs –t ext4 /dev/sdf

14. Mount EBS volume #sudo mkdir /disk1 #sudo mount /dev/sdf /disk1
#echo "/dev/sdf /disk1 ext3 defaults " | sudo tee –a /etc/fstab

15. Create snapshot of the EBS Volume

17. Amazon Simple Storage Service (S3)
Amazon S3 provides storage as a service to store and retrieve any amount of data at any time, from anywhere on the web.
