Amazon S3 File Gateway is a game-changer for businesses that need to manage multiple cloud storage systems.
It allows you to access your S3 bucket from your on-premises file server, making it easier to manage and transfer files between your on-premises environment and the cloud.
This solution is especially useful for businesses with large files or sensitive data that need to be stored securely.
With S3 File Gateway, you can seamlessly integrate your on-premises storage with the scalability and reliability of Amazon S3.
What Is S3?
S3 is Amazon's Simple Storage Service, which allows you to store and retrieve data as objects.
It's a key component of Amazon's cloud infrastructure, providing a highly scalable and durable storage solution.
Data stored in S3 can be accessed and manipulated programmatically using APIs, SDKs, and other tools.
S3 is designed to handle large amounts of unstructured data, such as images, videos, and documents.
This makes it a popular choice for applications that require fast and reliable data storage and retrieval.
How It Works
AWS S3 File Gateway is a file gateway that integrates with existing applications using file protocols like NFS and SMB. It's deployed on-prem servers as a virtual machine on popular hypervisors.
The gateway provides access to files or file share mount points stored as objects in S3. This allows you to store and retrieve files directly using NFS (version 3 or 4.1) or SMB (version 2 and 3).
You can also access your data stores in AWS S3 using any AWS Cloud application. This is a huge advantage for businesses that rely on AWS Cloud services.
To manage your data, you can use cross-region replication, lifecycle policies, and versioning. These features help ensure your data is protected and up-to-date.
Here are the file protocols supported by AWS S3 File Gateway:
- NFS (version 3 or 4.1)
- SMB (version 2 and 3)
AWS Storage Gateway
AWS Storage Gateway is an on-premise hybrid cloud storage solution that enables your applications to use AWS cloud storage services like S3 and Glacier.
It's deployed as a virtual machine or a hardware gateway appliance, utilizing storage protocols such as NFS, iSCSI, and SMB.
Storage Gateway provides very low latency network and disc performance due to its local caching.
This makes it an ideal solution for businesses that need fast and reliable data access.
By using Storage Gateway, you can reduce the cost of maintaining your on-premise storage solution, which has a significant impact on your business overall.
This is because you can eliminate the large upfront cost of hardware and shift to an operational expenses model.
AWS Storage Gateway is natively integrated with many other AWS services, allowing your data to be used by analytics, machine learning, logging, monitoring, and other products.
This means your data will benefit from all of the cloud services that it uses, including security, scalability, availability, and durability.
Storage Gateway supports encryption, data protection, and bandwidth management, providing a secure and efficient data transfer solution.
Data Migration and Verification
To migrate data to Amazon S3 using the File Gateway, you'll first need to mount the NFS share on a Linux server. This involves connecting to the On-Prem Linux Server instance using Putty and entering a command to create a directory and mount the share.
The command to create the directory and mount the share is located in the Storage Gateway file shares details screen. Once you've obtained the command, you can mount the NFS share by using it to create the mount point on the local directory.
You can verify that the share was mounted correctly by checking the disk space usage across different filesystems on the system. This is done by entering the command 'df -h', which provides a quick overview of the disk space usage.
To copy data to the share, you can use the command 'cp -r /media/data/*.png /mnt/nfs/s3', which copies all PNG files from the directory '/media/data' to the directory '/mnt/nfs/s3'.
Once the data is copied to the share, you can verify that it was successfully migrated to Amazon S3 by checking the S3 console. To do this, you'll need to search for the bucket that was created in the US East (Ohio) Region and verify that the image files are listed.
Here's a step-by-step guide to verifying the data migration:
- Search for and choose S3 to open the S3 console
- Select the bucket that was created in the US East (Ohio) Region
- Verify that the 20 image files are listed
- Return to the Buckets page and select the bucket that was created in the US West (Oregon) Region
- Verify that the image files were replicated to this bucket based on the policy that was created earlier
EC2 and Additional Setup
To set up an EC2 instance for your Amazon S3 File Gateway, you can use the CloudFormation template to create the Storage gateway instance and security groups, which can save you time and effort.
You'll need to select the Storage Gateway service Endpoint, and you can choose between VPC and Public based on your requirement. Make sure you have created a VPC interface endpoint for the VPC option.
To connect to the storage gateway, you'll need to access the Storage gateway console, which can be done by accessing the link generated during the setup process. If the link is not accessible, you can copy and paste it into a browser where the storage gateway is accessible.
You'll need to enter the gateway name and copy the Activation Code, which can be obtained by accessing the Storage gateway console. Enabling Cloudwatch logs is an optional step, but it's useful for auditing purposes.
Requirements
To set up Amazon S3 File Gateway, you'll need to configure Microsoft Active Directory. This is a crucial step in the process.
Ensure that your network has a minimum of 100 Mbps of bandwidth between the gateway and AWS. This will ensure smooth communication between your on-premises environment and the cloud.
You'll also need to configure your networking to connect Amazon VPC and your on-premises environment. This can be done using private networks, VPNs, or AWS Direct Connect.
To finalize the setup, use the AWS Management Console to verify that your gateway can resolve the name of your Active Directory Domain Controller.
Setting Up an EC2 Instance
To set up an EC2 instance, you can either launch one manually or use a CloudFormation template to create the Storage Gateway instance and security groups. I recommend using the template to save time and avoid a bit of ClickOps.
You'll need to select Amazon EC2 as the instance type and click Next. This will take you to the next step in the setup process.
You can choose to use a VPC endpoint or a Public endpoint, depending on your requirements. If you choose VPC, make sure you have created a VPC interface endpoint.
To connect to the storage gateway, you'll need to get the Activation code. If you choose IP address, ensure your default browser can access the storage gateway console.
Key Concepts and Learnings
To understand the Amazon S3 File Gateway, it's essential to grasp the key concepts and learnings.
The File Gateway service integrates on-premises environments with AWS cloud storage, allowing existing applications to access data stored in Amazon S3 as if it were local storage. This is achieved through the NFS (Network File System) mount.
Data replication to an S3 bucket is a crucial process, and AWS Storage Gateway facilitates this by acting as a bridge between the on-premises environment and AWS cloud storage.
A File Gateway with an NFS file share can be configured to migrate data from a Linux instance to an S3 bucket seamlessly.
Advanced Amazon S3 features like lifecycle policies and cross-Region replication enhance data management capabilities. Lifecycle policies enable automatic management of objects stored in S3 buckets, while cross-Region replication provides redundancy and disaster recovery capabilities.
Creating primary and secondary S3 buckets involves configuring bucket settings, including bucket name, region, and versioning. Enabling versioning ensures that multiple versions of objects are retained in the bucket.
Here are the key steps to consider when working with the File Gateway:
- Configuring a File Gateway with an NFS file share
- Replicating data from a Linux instance to an S3 bucket
- Enabling lifecycle policies and cross-Region replication
- Creating primary and secondary S3 buckets
