AWS Service- Storage

 Storages:


Types:


  • EBS - Elastic Block Storage


  • EFS - Elastic File Storage


  • S3 - SImple storage service


  • Glacier - Archival storage


EBS - Elastic Block Storage:


- It is a type of block storage 

- It can be attached only to a single instance in a single-zone

 

- OS volume - application critical data


EFS - Elastic File storage: 


-It is a type of Network shared storage 


-NFS principle


-common software, logs, company data


-It can be accessed only in a single region.


S3 - simple storage service: 


-It is a type of Object storage 


-It requires internet 


-commercial files (photo, videos, blogs)


Glacier - Archival storage: 


compressed data and storing in the tape drive 


  • company’s old data for auditing purpose


– Creating extra storage:



Practical Steps:


lsblk (list block)


mkfs.ext4 /dev/xvdf (create ext4 file system) 


mkdir /java (crate a fold to attach the new disk) 


mount /dev/xvdf /java (temporary mount) 


vi /etc/fstab (permanent mount entry) 


/dev/xvdf    /java  ext4  defaults 0 0



— Temporary mounting:




– Permanent mounting:




 EBS volume types 


  • general-purpose (cheap and best SSD HD) 


  • provisioned IOPS ( power and good performance SS HD) 


  • throughput optimized (HDD) 


  • cold HDD 


  • magnetic

– Creating Snapshot:


  • Disk backup is a snapshot  


  • right-click the volume and create a snapshot




– EFS:


use to share storage across Zones.


– Practical Steps: 


create efs in ec2 console and make sure that we are adding a Security group with NFS protocol enabled: 


NFS-2049


create 2 instances in 2 different zones and add the below software 


– Creating:



yum install -y amazon-efs-utils


mkdir /efs


server1:

mount -t efs -o tls fs-0d1126a3897c74703:/ /efs

cd /efs 


server 2:

mount -t efs -o tls fs-0d1126a3897c74703:/ /java

cd /java



permanent mounting :


vi /etc/fstab 


(man fstab)

0 - file system dump

0 - file system check 


fs-0d1126a3897c74703:/  /efs   efs defaults 0 0




–EFS Check (instance 1):




–EFS Check (instance 2):



— EFS permanent mount
