How Cloud Computing works

Here is a video that explains Cloud Computing in a simple way. If the video cannot be displayed properly it can be seen directly on YouTube.

Private Cloud Computing

The private cloud model is closer to the more traditional model of individual local access networks (LANs) used in the past by enterprise but with the added advantages of virtualization. The features and benefits of private clouds therefore are as follows.

Higher security and privacy

Public clouds services can implement a certain level of security but private clouds - using techniques such as distinct pools of resources with access restricted to connections made from behind one organisation’s firewall, dedicated leased lines and/or on-site internal hosting - can ensure that operations are kept out of the reach of prying eyes.

More Control

As a private cloud is only accessible by a single organisation, that organisation will have the ability to configure and manage it inline with their needs to achieve a tailored network solution. However, this level of control removes somes the economies of scale generated in public clouds by having centralised management of the hardware

Cost & Energy Efficiency

Implementing a private cloud model can improve the allocation of resources within an organisation by ensuring that the availability of resources to individual departments/business functions can directly and flexibly respond to their demand. Therefore, although they are not as cost effective as a public cloud services due to smaller economies of scale and increased management costs, they do make more efficient use of the computing resource than traditional LANs as they minimise the investment into unused capacity. Not only does this provide a cost saving but it can reduce an organisation’s carbon footprint too.

Improved Reliability

Even where resources (servers, networks etc.) are hosted internally, the creation of virtualised operating environments means that the network is more resilient to individual failures across the physical infrastructure. Virtual partitions can, for example, pull their resource from the remaining unaffected servers. In addition, where the cloud is hosted with a third party, the organisation can still benefit from the physical security afforded to infrastructure hosted within data centres.

Cloud Bursting

Opportunity to employ cloud bursting, in the event of spikes in demand. This service allows the provider to switch certain non-sensitive functions to a public cloud to free up more space in the private cloud for the sensitive functions that require it.

Managed Wireless

The growing BYOD driven professional use of personal mobile devices such as iPads in our business life, is typically creating an increasing demand for wireless network availability, bandwidth and security. Read more...

Wireless Teleworker VPN

The onSpirix Wireless Teleworker VPN is a smart plug-and-play solution that extends the corporate LAN to employees at remote sites with a centrally managed Wireless LAN Access point without requiring client devices (iPad, Notebooks, etc) to have client VPN software installed and running.
