MULTI CLOUD-ORACLE APPLICATIONS: EFS on AWS

Amazon EFS provides simple scalable,fully managed elastic NFS file system for use with AWS Cloud services and on prem resources.

It can built to scale on demand to petabytes without distrpting applications and growing and shrinking automatically.

you can avoid the complexity of deploying, patching, and maintaining complex file system configurations.

Write files to and read files from your Amazon EFS file system by using the NFSv4 protocol.

Any number of EC2 instances can work with your file system at the same time, and your instances can be in multiple Availability Zones in a regio

EFS creation

1.Need to creaete networkaccess

select VPC and required subnets where you want to create

2.Need to configure file system settings

select enable lifecycle managment(for price deduction we need to enable lifecycle policy to move not accessed for a periodlike 8daysor 15days..etc)

select throughput mode (based on you regular files transactions)

select performace mode(if required select max I/O)

select Enacryption(for security)

3.configure client access

set policy for client access(either root need to access by default others have read only like that)

4.Access Points

select filesystem owner/Group and permissions here

5.Review.

final step creation custom efs

when you create EC2 you need to select cusotm filesystem or you need to mount custom efs

After adding custom efs on ec2

the mount point show like the below

[ec2-user@ip-172-31-7-239 ~]$ df -h

Filesystem Size Used Avail Use% Mounted on

devtmpfs 475M 0 475M 0% /dev

tmpfs 492M 0 492M 0% /dev/shm

tmpfs 492M 464K 492M 1% /run

tmpfs 492M 0 492M 0% /sys/fs/cgroup

/dev/xvda1 8.0G 1.3G 6.8G 16% /

tmpfs 99M 0 99M 0% /run/user/1000

[ec2-user@ip-172-31-7-239 ~]$ cat /mnt/efs/fs1

once i deleted EFS in AWS

it will automatically unmount it and show like below
