With this development Amazon’s ‘Storage Gateway’ technology can not only talk with virtual systems based on VMware’s ESXi hypervisors but also with Windows-virtualized systems making it possible for e-commerce giant to infiltrate those areas where Microsoft had been a strong player – on-premise infrastructure management. The AWS storage gateway can now be used to create backups; store files; or for disaster recovery purposes.

Announcing the development over a blog post, Amazon wrote “With today’s launch of support for Hyper-V, you can now use the Storage Gateway on-premises in two of the most popular virtualization environments: Microsoft Hyper-V and VMware ESXi.”

“You can also run the Storage Gateway on Amazon EC2. This allows you to mirror your on-premises environment in the AWS cloud for on-demand computing and disaster recovery (DR)”, the post read further.

A Storage Gateway is basically a combination of a VM-based software appliance in a local server at a user’s local network and storage residing in the Amazon S3 cloud. The virtual appliance will be, in most cases, be loaded on an iSCSI device and the data storage will be made accessible to all client devices through either CIFS or NFS. Storage Gateways are one of the quickest ways to link on-premise datastores with AWS – the usefulness definitely limited by bandwidth made available to the gateway.

With the addition of Hyper-V support Amazon has taken another bite out of Microsoft’s pie as earlier this month it went about reducing the prices of its Windows cloud pricing by as much as 26 per cent.
