Mastering Enterprise Cloud Migration - A Practical Approach with AWS Storage Gateway
Introduction
Data migration is pivotal in the evolution of enterprise IT infrastructure in today's digital landscape. As businesses transition from traditional setups to cloud-based environments, the need for secure, efficient data transfer and storage solutions becomes increasingly apparent. AWS Storage Gateway, a versatile tool offered by Amazon Web Services (AWS), facilitates seamless integration between on-premises environments and cloud storage services like Amazon S3.
However, despite its versatility, the deployment of AWS Storage Gateway within private networks in the AWS environment remains a less explored topic. In this article, we detail leveraging the power of AWS Storage Gateway's file share feature within private subnets for secure data migration. Specifically, we will focus on mounting an S3 bucket onto an EC2 Windows instance hosted within the VPC's private subnet.
Understanding the Basics
1. AWS Storage Gateway in AWS VPC
AWS Storage Gateway serves as a bridge between on-premises data centers and AWS cloud storage services, facilitating seamless data transfer and storage integration. While it is commonly deployed in public subnets, deploying AWS Storage Gateway within a private subnet offers enhanced security benefits by restricting direct access from the internet. This setup is particularly crucial when mounting S3 buckets onto Windows servers located in private subnets, ensuring that sensitive data remains shielded from external threats and protected behind layers of robust security measures.
2. Amazon EC2
Amazon EC2 allows users to rent virtual machines (instances) on which they can run their own applications. EC2 instances can be easily scaled up or down based on demand, providing flexibility and cost-effectiveness for hosting a wide range of computing workloads in the cloud.
3. Amazon S3
Amazon S3 is a highly durable and scalable object storage service designed for secure and efficient data storage. It offers scalable storage for storing and retrieving data. S3 allows users to store and retrieve any amount of data from anywhere on the web, making it ideal for a wide range of use cases, including backup and recovery, data archiving, and content distribution.?
Now, let’s delve into the steps for mounting an AWS S3 bucket on an Amazon EC2 instance.
Prerequisites
Step1: Set Up an Amazon S3 File Gateway Using AWS EC2 as a Host
(a) Select an appropriate instance type, with m5.xlarge being the minimum requirement.
(b) Configure the network settings to use a VPC and choose a private subnet while disabling auto-assign public IP.
(c) Create a security group within the VPC and define inbound rules to allow traffic from your VPC CIDR range into the specified TCP ports - 443, 1026, 1027, 1028, 1031 & 2222, and UDP ports - 20048, 111 & 139? as well as port 80 for all traffic.
(d) Attach this security group to the Storage Gateway EC2 instance.
(e) Add storage to the gateway instance by selecting "Add new volume" under storage settings. At least one Amazon EBS volume for cache storage with a minimum size of 150 GiB, in addition to the Root volume, must be added.
(f) Launch the instance and ensure that its status shows as "Running" with a check mark indicating that the status check is complete.
6. Copy the Private IPv4 address of the Windows EC2 server for further configuration.
Step 2: Create the VPC Endpoint?
Interface Endpoint?
The interface endpoint enables secure and private connectivity from the VPC to the AWS Storage Gateway service.
4. Choose the relevant Availability Zone and a private subnet where the S3 File Gateway is deployed.
5. Create a new endpoint security group within your VPC.
6. Navigate to the EC2 console, select "Security Groups" in the navigation pane, and edit the inbound rules to allow all traffic from the security group itself.
7. Return to the Create Endpoint page, choose the newly created security group under Security groups, and create the endpoint.
8. In the Endpoint Options, select "VPC hosted" and choose the VPC endpoint created earlier. Proceed to create the storage gateway.

9. Copy the first DNS name from the list of endpoints under Details.
Gateway Endpoint
The gateway endpoint facilitates private access to Amazon S3 from your VPC.
Step 3: Obtain the Activation Key for the Amazon S3 File Gateway
4. This request will return an activation key, for instance, B8165-IS79A-BEHJR-6CNK9-FHN86
Step 4: Deploy S3 File Gateway
3. On the Activate gateway page, finalize the deployment process by choosing "Activate Gateway."
Step 5: Create the NFS file share
Step 6: Mount your NFS file share
3. Connect to the EC2 Windows server where you intend to mount the S3 drive and open the Command Prompt.?
4. Execute the command obtained from the file share, ensuring that the desired drive letter is specified. For instance, using "D:" as the drive letter: net use D: \10.1.1.191\prod-blueco-bucket /user:sgw-F2BC199B\smbguest
Step 7: Validate that your mount is successful
2. Upload a file to your S3 bucket
3. Login into your Windows server and confirm that the uploaded file is present in the mounted drive?
Conclusion?
AWS Storage Gateway offers a powerful solution for seamless data integration within AWS cloud environments. By leveraging its file share feature within an AWS VPC, organisations can mount S3 buckets onto EC2 instances, facilitating efficient data migration and access. Embracing this approach enables enterprises to harness the scalability and flexibility of cloud storage while adhering to security and compliance requirements. As cloud adoption continues to accelerate, AWS Storage Gateway stands as a vital tool for modernising data management workflows and driving digital transformation initiatives.
