CloudSigma Cloud

Overview

CloudSigma marries the latest generation virtualisation technology at the backend with
intuitive front-end management and access tools. Our aim is to provide accessible and easy to use Infrastructure-as-a-Service (IaaS) making utility computing a reality.

CloudSigma is a pure IaaS provider. This means we don’t place restrictions on the software that you run on your servers or the level of access you have. We give all our customers full control to scale, install and customise servers to fit their needs, not ours.

As a pure cloud provider CloudSigma has been able to design its infrastructure specifically for use in a cloud platform without legacy systems. From the ground up we have incorporated high levels of resilience and redundancy which allows us to offer all our customers a 100% SLA. Unlike many cloud providers, we are open and transparent about the hardware choices we make and why we make them.

It is a fact that all hardware suffers from failure at one time or another. To prevent loss of availability and data it is therefore imperative to incorporate as much redundancy as possible to eliminate single points of failure. The CloudSigma cloud runs on custom infrastructure designed specifically for the task.

Our customers benefit from our cutting edge technological innovation. By deploying the latest technology we aim to make their computing more convenient and flexible. One great example is our free in-browser VNC service available to all. Eliminating the need to use a standalone VNC client, our service works behind corporate firewalls through most modern web browser.

Benefits

Fully Independent Scalable Resources
On the CloudSigma platform you can specify exactly how much CPU, RAM, Storage and Bandwidth you require independently. We don’t bundle resources together. If you are a high CPU user for example you won’t have to purchase bundled RAM which you don’t need! If you need a lot of storage but less CPU and RAM likewise no problem. There are no ‘standard‘ server size on the CloudSigma cloud.

Run Any Operating System and Software That You Like
CloudSigma does not place any restrictions on the operating systems or software that you run on your virtual servers. As long as the operating system can run on standard Intel/AMD architecture it will run on CloudSigma.

No Meaningless New Jargon
We provide the same computing resources and networking as traditional dedicated hosting but in a flexible instantly scalable form and with more efficient billing and usage models. Cloud computing doesn’t mean we need new names for old concepts so we keep it simple. A static IP address is called a static IP address, a VLAN is, well, a VLAN etc.

Virtual Servers That Behave like Real Servers
The CloudSigma system is designed so that virtual servers behave like traditional physical servers. Users can start, stop and restart them. Users can mount and unmount drives and customise networking settings like adding a static IP or VLAN.

Guaranteed CPU, RAM and Storage Allocation
CloudSigma uses the latest generation of virtualisation technology which allows it to guarantee fully reserved RAM and storage allocations without over-subscription. We also offer a minimum CPU availability proportional to reserved size. That means the total CPU available on a machine is shared pro-rata between virtual server instances subject to a minimum allocation. At times when the CPU is not fully allocated, virtual server instances on our cloud will actually have MORE CPU allocated to them than the user is paying for. We can’t see any reason to limit the CPU a user receives when there is free CPU and of course that additional CPU allocation is not charged for.

Persistent Servers and Storage
All CloudSigma virtual servers are persistent. Once created whether a server is started or stopped it will remain in that user’s account ready to use. Likewise, all storage is written to a user’s virtual drives. Data written to virtual drives persists and is available in the future whether or not the server that that drive is currently associated with is running or not.

Automatic Redundancy and Failover
In the unlikely event that there is a software or hardware failure that causes a host to stop working, the virtual servers will automatically start-up once that failure has been resolved. Most outage events (although rare) last just minutes. Automatic redundancy and failover allows our users to configure their virtual servers‘ software to continue working automatically after a server restart ensuring easy management and higher levels of availability. A user can manually reboot a virtual server instance at any time.

Full Control via API or Web Console
CloudSigma’s philosophy is to give maximum flexibility and control to users of our cloud. We allow all account actions to be executed via our API or innovative web console. Whether you are new to cloud computing or an experienced veteran, you will be able to access and control your virtual server instances and drives on many levels, irrespective of technical ability and experience.
