Ashish Nadkari discusses cloud NAS in this Q&A. His answers are also available as an mp3.
What is cloud network-attached storage (NAS) and how does it work?
Cloud NAS is a subset of cloud storage, which is also known as Storage as a Service (SaaS). When most people think about NAS, they think about a storage device in their data center or office. If you take that device and move it far away, maybe where you don’t even know the location, and you access it over the Internet using a software module on the host itself, you’re taking the functionality of the NAS device and you are moving it into the cloud. You just access it as if it is a local device.
That’s cloud NAS in a nutshell. It’s a spoof on the server, making it think it’s accessing a local device when really it’s over the Internet or a dedicated long-distance connection.
What are the benefits of cloud NAS?
Well, with a typical NAS device, you are stuck with that location. So if something goes wrong with that location, your services are going to be down. So, if you have a critical file serving requirement, and if you are out somewhere traveling and need to access it, but the router in your office went down, you are out of luck. But, if you move it into the cloud it is virtually available and always available. The key benefit is that you can access your information at any time without the restrictions of the physical location of the data.
What are the drawbacks of cloud network-attached storage?
The main drawback of cloud NAS is that it is as fast or as slow as the network connection that it is accessed over. So, if you are on a dial-up connection and you are trying to access data, the access is going to be very slow. So, it isn’t ideal for large files or large chunks of data. It should be used for small subsets of data or specialized applications such as backup because latency can be a big issue.
You need to have a local copy available to work on and then you can just save it over the network as a backup.
