How can digitalocean.com be Cloud, if they use KVM on Single Servers?
Hi all,
This all cloud definition and standards is really confusing me. The most recent thing thas has come up that take my attantion was digitalocean.com ssd cloud servers services.
They call it "Cloud SSS Servers" but how can it be a cloud if they are based on KVM and hosted in single dedicated servers with storage runing RAID inside the server?
Can anyone explain this to me? Are they really a cloud provider or this can be consider has false advertising from their end?
Thanks

Their definition of cloud is:
https://www.digitalocean.com/what-is-cloud-hosting
It has nothing to do with redundancy, fault tolerance, high availability etc... in other words, it's just another VPS provider..

Its a cloud as it's easy to provision with hourly billing and you can spin up / destroy servers as you require.

Ok, so if i understand correclty is a cloud because of its provisioning and billing flexibility / model.
Regarding other features commonly seen on a cloud like redundancy, shared sans, etc.. does not exist.
In a simple way, digitalocean.com, just seels standard vps servers with a very flexible provisioning and billing, is this correct?
Thanks

Hi Kingfish85,
On the link you provided where digitalocean.com describes its own definition of a cloud service it says under the Secure feature the following and i quote:
"By distributing server data across redundant servers, information hosted in the cloud is protected against hardware failure."
How is this possible if their vps servers are using just local raid storage?
Thanks

That correct. To tell the trust about 90% of "cloud" provider use same technology. So if you want real cloud you need try to find real cloud provider. Please also note that real cloud will cost you more than above "cloud" due to more expensive h/w and s/w. Also sometimes you will need modify your web application to comply cloud terms.

Pedrojose, keep in mind WHT (with the exception of some posters above) is a bit skewed in its definition of cloud as its very small-scale and SANs centric. If you visit sites dedicated to high scalability or even the IEEE cloud conferences, Digital Ocean and others like it that concentrate on provisioning and the capacity planning behind it are closer to the cloud definitions there.
Yes, it is basically a VPS with flexible provisioning. Is it false advertising? No. Their definition just aligns better with their target demographic.
As for the "By distributing server data across redundant servers" bit, I think they really ought to rewrite that. They might have been referring to the ability to transfer volume image snapshots across regions, but that's so poorly worded it gives everyone the wrong impression.Last edited by tchen; 11-26-2013 at 03:26 PM.

Cloud is just a marketing term. As most people are only looking for cheapest price, not quality or redundancy, Digital Ocean does what the market asks for.
It is really hard to stand out as a High-Availability provider because most customers prefer cheap price and the opportunity to complain about bad service later.

Cloud computing is a general term for anything that involves delivering hosted services over the Internet
A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour; it is elastic -- a user can have as much or as little of a service as they want at any given time

this is partly true - and its a fair comment as once marketing got ahold of the term, it can and is regularly abused.
having said this, what cloud computing actually and fundamentally represents, is the transformation of IT into a utility.
well, redundancy is not mutually exclusive with having a SAN backend. A SAN backend may or may not be redundant itself, so, simply having a SAN and having hypervisor failover isnt enough for high availability. There is also enough data out there where a redundant local storage RAID array has been shown to be more reliable and demonstrate better performance then SAN based storage - it strictly depends on how each environment is setup. If these nodes are built properly, disk, network, etc are all redundant. Are there single points of failure in such setups? of course there are, but, there is a strong argument to be made that many local storage environments are more reliable and demonstrate better performance then many/most SAN based environments.
Also, the concept of utilizing infrastructure to achieve high availability is a bit archaic - or, at the very least - represents a transition period. why accept the native performance loss of moving storage to the network (vs the server backplane) when applications are being built to accommodate HA and do not want or need the infrastructure to try and compensate for poorly written applications. This becomes even more important when one realizes that the primary failure point is not hardware, but, rather services running on the virtual machines (ie IIS, Apache, MySQL, etc). Building high availability applications is the ultimate end game for cloud computing, and turning infrastructure into simple commodities. utilizing fail over at hypervisor layers is nice and has many valid use cases - but, it is not really a determining factor on cloud vs not cloud
In a simple way, digitalocean.com, just seels standard vps servers with a very flexible provisioning and billing, is this correct?

I do not agree with DigitalOcean's definition of cloud. It seems like they're just offering virtual private servers just like most providers do. They're definitely really affordable though, I can give them that. But I would not go with them if you're looking for the same redundancy and failover that a proper cloud set up can offer.

Cloud is simply a marketing term. You will always want to inquire about their infrastructure if it is not clearly outlined when purchasing said products.
