NFS File shares migration On-Prem to AWS S3 using Storage Gateway

Introduction

Migration of file shares from an on-premises Linux instance to AWS, utilizing Storage Gateway for S3 in the Ohio region (us-east-2), with cross-region replication to Oregon (us-west-2).

Architecture

The migration is executed as a one-time operation using NFS on a Storage/File Gateway. Originating from on-premises Linux instances hosting various directories, images, and files, the migration targets an S3 bucket in the AWS Ohio region, with automatic cross-region replication to Oregon for redundancy and disaster recovery purposes.

AWS Services

• Virtual Private Cloud (VPC): Configured with 6 subnets spanning 2 different AZs for redundancy and fault tolerance.
• Subnets:
  • Public Subnet: Hosts the on-premises instance and appliance instances with the File Gateway mounted.
• S3: Serves as the primary storage for migrated files using File Gateway.
• S3 Cross Region Replication: Replicate the files on S3 to another region for backup.
• Security Groups: Secure acces for the EC2 instances to HTTP, HTTPS, NFS and SSH.
• AIM Roles: Define the access policies to the services.
• Policies: Policies design spesifically for File Gateway to access S3.

Additional AWS Components

Repository Contents

Within this repository, you will find:

• CloudFormation Templates: The CloudFormation directory contains all the YAML templates used to define the AWS resources.
• Images: The SSH conection to the On-Prem instance to configure and perform the migration.
• Script.sh: The Script used to autogenerate Images and files (2.6GB) to migrate.
