Cloud computing is the new IT trend that is grabbing the industry magazine headlines, and despite the fact that it is becoming positively embraced by a lot of users, some are needlessly worried about security issues.
Bringing together the 3 main trends of virtualisation, utility computing and software as a service (SaaS), cloud computing is still regarded with a degree of suspicion by some. Even so, as both the US and UK governments utilise the technologies they at least have no doubts over its use.
It is the combination of the 3 component parts of cloud computing that make it especially appealing to users as they need to have little or no knowledge of the technology needed to operate it. 1st utilized to describe big ATM networks in the early 1990s, when used in the computing context ‘Cloud’ is describing the web and the way that resources are employed across its entirety. It entails the provision of services to users who don’t have to worry about any of the technical issues surrounding the service.
Because resources can be pulled from across the web it means that cloud computing solutions are entirely scalable and peak loads are simply accommodated. That permits users to go about their company with out having to worry about allocation of CPU, storage or network bandwidth.
The shared hosting infrastructure model in standard use right now is limited by the physical constraints of the offered hardware, typically at one bottleneck point, such as single server. However, cloud hosting has no such restrictions as it utilises the processing power of a series of servers in actual time. A user of cloud hosting basically purchases as much processing capacity as they require from a resource that is virtually inexhaustible and consequently provides a seamless service regardless of peaks and troughs in visitor numbers.
Intelligent systems basically make certain that load-balancing is applied across a series of servers, adding or removing them from the cluster as necessary offering an invisible transition for clients. The technologies underpinning the infrastructure enables small and medium–sized enterprises to utilise internet hosting architecture in a way that was only offered a big corporate IT department a few years ago.
Cloud technologies is now utilised by major corporations and governments throughout the world. It is undoubtedly no fad, and despite myths about its lack of security is virtually as robust as any traditional method it is dependent upon the good quality of the software and operator. There are also varying kinds of cloud, such as an on-premise cloud or a virtual private cloud, which are as secure as the method operator wishes them to be as it is in a private environment. However you would be constrained to your pre-configured environment.
