Before discussing AWS Storage Gateway. As the number of organizations migrating their on-premise solutions to cloud-based applications increases, so does the challenge of ensuring a successful transition. In particular, there are challenges associated with data migration and business planning. This article will discuss those challenges and guide how to address them best when transitioning an application from an on-premise solution to the cloud.
Data migration is one of the most significant challenges of migrating an existing application to a cloud-based platform. This process involves moving data from the on-premise solution to the cloud, which requires careful planning and preparation. To ensure a successful migration, organizations should consider aspects such as data continuity, compatibility with cloud services, data security, and privacy, availability of resources, cost optimization, and scalability.
Business planning is another critical factor in successful cloud migration. As the application moves from an on-premise solution to a cloud platform, businesses must consider how their operations will change. This may include changes to staff responsibilities, adoption of new technologies and practices, and associated potential costs. Planning for these changes in advance is essential to avoid surprises.
Finally, organizations should consider the long-term implications of migrating an application to a cloud platform. This includes ensuring the cloud solution meets their performance, scalability, and stability needs. In addition, as the application evolves, organizations should consider adapting it to take advantage of emerging technologies such as artificial intelligence and machine learning.
Storage Gateway
What is AWS Storage Gateway?
Transform how you store data with AWS Storage Gateway, a low-latency hybrid cloud service that provides your business access to virtually infinite cloud storage from your on-premises.
It doesn’t improve for businesses seeking to store and back up their data without breaking the bank. Not only are cloud scalability and reliability included in our service, but we also provide flexibility with multiple storage protocols like NFS, S3 API, and iSCSI – all tailored towards your application’s needs! Furthermore, you can take advantage of caching recently accessed files on-premises for quick access, plus look forward to unlimited cloud storage capacity that automatically adjusts itself depending on demand.
With AWS Storage Gateway, organizations can quickly achieve low-cost disaster recovery, archiving, and backup solutions that can be scaled up or down as needed.
Virtual Machine
The AWS Storage Gateway also provides a virtual machine (VM) that can be quickly and easily deployed on your data center or EC2 for free. This VM offers a range of features, including the ability to rapidly provision storage devices, connect directly to cloud services such as Amazon S3, and support multiple protocols like NFS and iSCSI.
By leveraging these features, businesses can reduce costs by storing their data in the cloud while enjoying local access. In addition, with this easy-to-use VM, organizations can quickly configure an environment that fits their unique needs, allowing them to focus on value-added activities rather than IT infrastructure management.
AWS Storage Gateway Types
AWS Storage Gateway offers three gateway types to suit your specific storage needs, File Gateway, Volume Gateway, and Tape Gateway.
With File Gateway (NFS), you can store and retrieve objects ranging from 0 bytes to 5 TB in size. File operations such as create, read, update, and delete are all available, and File Gateway supports both file-based and object-based access via NFS and S3 API protocols. File Gateway also provides versioning, lifecycle management, and cross-region replication features.
Volume Gateway (iSCSI) offers block storage for applications requiring low-latency data access, such as databases. With Volume Gateway, you can create iSCSI block volumes and mount them as network drives on your existing on-premise servers. You can also take snapshots of these volumes for backup purposes or replicate data to other AWS regions for increased reliability.
Tape Gateway (VTL) is a virtual tape library solution that provides an economical way to store infrequently accessed data such as backups, archives, and disaster recovery solutions. Tape Gateway uses popular transport protocols such as iSCSI and NDMP to access data stored in VTL tapes while providing the same features traditional physical tape libraries offer. With Tape Gateway, organizations can benefit from low-cost storage and improved availability compared to physical tape libraries.
Storage Gateway Cached Volumes
AWS Storage Gateway Cached Volumes is one of the two deployment models offered for the Volume Gateway service, the other being Stored Volumes.
With the Cached Volumes model, businesses can keep frequently utilized data close by with an on-premises cache while tucking away less regularly accessed information in Amazon S3. This allows companies to take advantage of the scalability and affordability benefits of storing large amounts of data in Amazon S3 without sacrificing quick access times for critical information that remains locally stored.
Here are some key features of the Storage Gateway Cached Volumes deployment model:
- Low-latency access: Cached Volumes provide low-latency access to frequently accessed data stored in the on-premises cache, which helps improve application performance.
- Cost-effective: Storing less frequently accessed data in Amazon S3 can help organizations reduce storage costs.
- Flexible storage options: Cached Volumes support up to 32 volumes with a maximum capacity of 32 TiB per volume.
- Data protection: Cached Volumes support volume-level snapshots, enabling organizations to create point-in-time data backups.
- Easy integration: Cached Volumes can be easily integrated with existing on-premises applications using industry-standard storage protocols such as iSCSI.
It’s important to note that Cached Volumes are designed for workloads that require low-latency access to frequently accessed data. In contrast, Stored Volumes are better suited for workloads that require low-latency access to all data stored on the gateway. Therefore, organizations should evaluate their storage requirements and choose the deployment model that best meets their needs.
AWS Storage Gateway – Hardware Appliance
AWS Storage Gateway hardware appliance is a physical device that can deploy the Storage Gateway service on-premises. It is designed to provide a low-latency, high-throughput connection between an organization’s on-premises infrastructure and the AWS cloud.
The hardware appliance is pre-configured with the Storage Gateway software and can be deployed quickly and easily. Once deployed, it can be managed using the same AWS Management Console, APIs, and CLI as the virtual Storage Gateway appliances.
Here are some key features of the AWS Storage Gateway hardware appliance:
- High performance: The hardware appliance is designed to provide high-throughput, low-latency access to AWS cloud storage.
- Simple deployment: The appliance can be deployed quickly and easily, with minimal configuration required.
- Seamless integration: The hardware appliance can seamlessly integrate with an organization’s existing on-premises infrastructure and applications.
- Low maintenance: The appliance is designed to require minimal maintenance, with automatic updates and backups.
- AWS KMS CLI Security: The appliance is designed with safety in mind, with support for encryption in transit and at rest and the ability to integrate with AWS Key Management Service (KMS) for key management.
It’s important to note that the AWS Storage Gateway hardware appliance is only available in select regions and requires a minimum commitment of 3 years. Therefore, organizations should evaluate their storage requirements and the cost of ownership before considering the hardware appliance as a deployment option.
