Create EFS(Elastic file system) Using Cloudformation

 

What is Amazon Elastic File System?

• Amazon Elastic File System (Amazon EFS) provides a simple, serverless, set-and-forget elastic file system for use with AWS Cloud services and on-premises resources.
• It is built to scale on-demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth.
• Amazon EFS has a simple web services interface that allows you to create and configure file systems quickly and easily.
• The service manages all the file storage infrastructure for you, meaning that you can avoid the complexity of deploying, patching, and maintaining complex file system configurations.
• Amazon EFS supports the Network File System version 4 (NFSv4.1 and NFSv4.0) protocol, so the applications and tools that you use today work seamlessly with Amazon EFS.

Steps to create resources in cloudformation

Search Cloudformation in aws console

Create a new Stack

A stack is a collection of AWS resources that you can manage as a single unit. All the resources in a stack are defined by the stack’s AWS CloudFormation template

Save the below code in .yaml format & then upload a file after that click next.
