Cloud Storage for Your File Server

How much bandwidth you need to run file server with cloud storage?

As I was explaining Gladinet CloudAFS to a group of IT people as a file server with cloud storage attached, one question I got was:

How much bandwidth you need to run file server with cloud storage?

It is very obvious where the concern is coming from. If I had an on-premise file server, with cloud storage attached as tier 2 storage, will the slowness of the Internet (as compared to LAN) slow down the file server activities?

Rest assured, Gladinet CloudAFS takes care of this. Specifically, it takes care of two issues.

A. Slow Internet to the Cloud Storage – that is why it is tier2 storage.

B. There is a glitch, Internet is down.

The secret to both maintain local LAN performance and leverage Cloud Storage is to have a tier 1 storage locally on the hard drive (or NAS or SAN). When people read and write to the file server, it is writing to and reading from the tier 1 storage, thus gives you an impression of local storage because it is indeed local storage.

Gladinet CloudAFS will then schedule transfer to and from the tier 2 storage asynchronously.  You can schedule the transfer to be 12 hours later than the tier 1 storage hit so it can happen at night when nobody is working. If the Internet is down at a moment, the transfer will resume and retry later on.

Use Case 1 – File Server Backup

When your Internet is slow or the Internet is not quite reliable, you need to put cloud storage to a more secondary role, such as backup.

In this use case, you can configure Gladinet CloudAFS tier 1 storage to have the same size as tier2 cloud storage. This way, the read/write is always from local and you are guaranteed to have 100% up time and 100% local performance. The cloud storage is something nice to have just in case that your local server crash or out of capacity, you can get it back immediately by provision another CloudAFS server (5 minute install when OS is ready).

The benefit of this use case is that you can always quickly re-provision your file server in case something happens to it.

Use Case 2 – Cloud Storage Gateway

When your Internet is fast and the Internet is reliable, you can put cloud storage to a more prominent role, or on the other hand, put CloudAFS to a more secondary role such as a Cloud Storage Gateway with cache.

For example, if you file server is with Amazon EC2 and your storage is Amazon S3, you know you have fast and reliable connections in between, you have a fit for the Cloud Storage Gateway use case.

Another example, if you are hosting with Peer1 server and also using Peer1’s CloudOne storage, you have a fast and reliable connection in between too. This case fit you as well.

In this case, the local cache on the CloudAFS can be smaller than the actual cloud storage capacity.

When the cache is smaller, you will incur cache miss if a read to the CloudAFS server doesn’t already have the file locally. This case the file needs to be fetched from the cloud storage over the Internet. Since you have fast and reliable connection, this first time and one time cost is OK.

The benefit of this use case is that you can ship a lot of data over to cloud storage. For example, you can turn local backup software to cloud backup software by pointing the backup destination to CloudAFS.

CloudAFS Parameters

The two biggest parameter for CloudAFS are

A. How big the local cache is. The slower and less reliable the Internet is, the bigger the local cache you will need to assign.

B. Scheduled flush time. CloudAFS use a write-through cache with flush schedule. The slower the Internet you have, the more delay you will need to push the synchronization to night time.

At this time, CloudAFS supports a wide variety of cloud storage providers, including Amazon S3, Windows Azure, Rackspace Cloud Files, EMC Atmos, Mezeo, OpenStack, Nirvanix, AT&T Synaptic Storage, Peer 1 CloudOne and more.

Speed is an important factor when you apply cloud storage to file server. Visit other earlier posts about how to pick a cloud storage providers.

As we approach the next @ThingsExpo, to be held June 9-11 at the Javits Center in New York, my thoughts naturally turn to the Internet of Things. The IoT is a leviathan—in the best possible sense of the term—that will sweep up most everything in the ocean of data and technology being created today and tomorrow. But rather than try to grasp all of its possible uses, for today I'm looking at “just” the Industrial Internet part. I just read a long paper co-authored by Tim Berners-Lee about the possibility of describing a “web science,” that is, discipline that combines the study involved ...

Wearable technology was dominant at this year’s International Consumer Electronics Show (CES) , and MWC was no exception to this trend. New versions of favorites, such as the Samsung Gear (three new products were released: the Gear 2, the Gear 2 Neo and the Gear Fit), shared the limelight with new wearables like Pebble Time Steel (the new premium version of the company’s previously released smartwatch) and the LG Watch Urbane. The most dramatic difference at MWC was an emphasis on presenting wearables as fashion accessories and moving away from the original clunky technology associated with t...

As Marc Andreessen says software is eating the world. Everything is rapidly moving toward being software-defined – from our phones and cars through our washing machines to the datacenter. However, there are larger challenges when implementing software defined on a larger scale - when building software defined infrastructure. In his session at 16th Cloud Expo, Boyan Ivanov, CEO of StorPool, will provide some practical insights on what, how and why when implementing "software-defined" in the datacenter.
There is no doubt that Big Data is here and getting bigger every day. Building a Big Data infrastructure today is no easy task. There are an enormous number of choices for database engines and technologies. To make things even more challenging, requirements are getting more sophisticated, and the standard paradigm of supporting historical analytics queries is often just one facet of what is needed. As Big Data growth continues, organizations are demanding real-time access to data, allowing immediate and actionable interpretation of events as they happen. Another aspect concerns how to deliver ...
So I guess we’ve officially entered a new era of lean and mean. I say this with the announcement of Ubuntu Snappy Core, “designed for lightweight cloud container hosts running Docker and for smart devices,” according to Canonical. “Snappy Ubuntu Core is the smallest Ubuntu available, designed for security and efficiency in devices or on the cloud.” This first version of Snappy Ubuntu Core features secure app containment and Docker 1.6 (1.5 in main release), is available on public clouds, and for ARM and x86 devices on several IoT boards. It’s a Trend! This announcement comes just as...
WebRTC defines no default signaling protocol, causing fragmentation between WebRTC silos. SIP and XMPP provide possibilities, but come with considerable complexity and are not designed for use in a web environment. In his session at @ThingsExpo, Matthew Hodgson, technical co-founder of the Matrix.org, discussed how Matrix is a new non-profit Open Source Project that defines both a new HTTP-based standard for VoIP & IM signaling and provides reference implementations.
The security devil is always in the details of the attack: the ones you've endured, the ones you prepare yourself to fend off, and the ones that, you fear, will catch you completely unaware and defenseless. The Internet of Things (IoT) is nothing if not an endless proliferation of details. It's the vision of a world in which continuous Internet connectivity and addressability is embedded into a growing range of human artifacts, into the natural world, and even into our smartphones, appliances, and physical persons. In the IoT vision, every new "thing" - sensor, actuator, data source, data con...
