### Instance store Volumes 


| info  | Links  |
| ------------ | ------------ |
|  Amazon EC2 instance store |  [Link](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/InstanceStorage.html) |

- Ephemeral storage
- Donot store critical data
- if instance is start or stop you will loose data
- if rebooted the data will remain intact
- If EC2 failed the data will be lost. (Start/Stop, Terminate)
- No additional fees
- IOPS are blazing fast 
- mainly used as cache or buffer
- Not all Ec2 Support Instance store volume

### Amazon EBS Volumes

| ------------ | ------------ |
|How to Encrypt an EBS Volume  | [Link](https://cloudacademy.com/blog/how-to-encrypt-an-ebs-volume-the-new-amazon-ebs-encryption/)  |

- Persistence and block level storage.
- Can be attached to Ec2 instance & in some regions we can multi attach the EBS Volume. [More info on multi attach](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volumes-multi.html)
- Independent of EC2 instance 
- Logically attached to EC2 instance
- Supports Snapshotting 
- can copy EBS snapshot from one region to other regions
- EBS data is replicated to same AZ for Availability. 
- [Types of EBS](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volume-types.html) are SSD And HDD.
- Ability to encrypt during rest and transit (AES256). Here is an awesome blog about this by [STUART SCOTT from Cloud Academy](https://cloudacademy.com/blog/how-to-encrypt-an-ebs-volume-the-new-amazon-ebs-encryption/)


### Amazon Elastic File System (EFS)

|How to create EFS|[Link](https://docs.aws.amazon.com/efs/latest/ug/gs-step-two-create-efs-resources.html)|

- EFS , a file storage services
- Can attach to multiple EC2 using mount point
- Uses Hierarchy system.
- Build under Gluster filesystem
- Fully managed shared file system with low latency access
- PB of Storage available
- Uses NFS 4.1 and  4.0 
- replicated across multiple AZ for high availability
- Highly scalable, regional services,  available on most of the regions [For more info](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/)

- Content Delivery Network
- Delivered as cache data from edge locations

**Use Distributions to deliver content**

 **Via Web distribution**
  - Dynamic and Static
  - HTTP and HTTPS
  - Allow add, remove, update object
  - Live stream functionality support
  - Origins can be Ec2 or S3

 **Via RTMP Distribution**

  - Origins can only from S3

Amazon CloudFront is a content delivery network (CDN) provided by Amazon Web Services (AWS). It is designed to deliver content, such as websites and applications, quickly and securely to users around the world. CloudFront uses a network of edge locations located in various parts of the world to deliver content to users with low latency. This means that users can access the content they need faster and with fewer interruptions. CloudFront also integrates with other AWS services, such as Amazon S3 and Amazon EC2, to provide a complete solution for delivering content over the internet.

- Volume can be 1GB to 16 TB and MAX 512 TB.
- Snapshots are stored inclemently in S3.
- Cached Volume gateways, data provided by s3. local volume used for buffering and local cache for recently access data.
- Volume can be 32TB,  and storage capacity of 1024 TB
- Tape gateway , back to s3 from on-prem ,take advantage of AWS glacier

AWS Snowcone is a small, rugged, and secure device offering edge computing, data storage, and data transfer on-the-go, in austere environment with little or no connectivity.


These devices are designed for offline data processing and storage, and are particularly useful for transferring large amounts of data to or from AWS when dealing with data that is too large or too costly to transfer over the Internet.

AWS Snowball is a physical device that can hold up to 50 TB of data, while AWS Snowball Edge is a device that combines the capabilities of AWS Snowball with additional compute and storage capabilities. AWS Snowmobile is a shipping container that can hold up to 100 PB of data, and is designed for transferring extremely large amounts of data to AWS.
